The AmScope T490A-DK compound trinocular microscope has a sliding head, interchangeable pairs of 10x widefield and 16x widefield eyepieces, a forward-facing nosepiece with four DIN achromatic objectives, Brightfield and Darkfield halogen illumination, and a double-layer mechanical stage with a stage stop to protect slides and objectives from damage. The trinocular viewing head has a vertical camera mount and a compensation-free binocular viewing head with interchangeable pairs of WF10x and WF16x eyepieces and sliding head to adjust inter-pupillary distance, a fixed 30-degree vertical inclination to reduce eye and neck strain, and a 360-degree rotation capability to provide a more comprehensive view and enable sharing. A Siedentopf binocular head enables the viewer to change the interpupillary distance without changing the tube length, eliminating the need to re-focus the image. It has an interpupillary range of 55 to 75mm to accommodate individual eye differences, and bi-lateral dioptric adjustment accommodates individual eye-strength differences. The vertical trinocular port accepts a camera with a 23mm or C-Mount adapter (camera sold separately). The forward-facing nosepiece has 4x, 10x, 40xS (spring), and 100xS (spring, oil) DIN achromatic optical-glass objectives that combine with the eyepieces to provide color correction of magnified images. The 40xS objective is spring loaded to prevent slide damage when focusing. The 100xS spring-loaded oil-immersion objective uses oil between the specimen and the objective lens to provide increased resolution over a standard objective. A compound microscope is used for inspection and dissection of specimens when two-dimensional images are desired.
The microscope has lower (transmitted, diascopic) Brightfield/Darkfield (BF/DF) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. The dry darkfield condenser has a 0.7-0.8 NA. Halogen illumination provides bright light in a concentrated path and has a rheostat to control light intensity. The 1.25 NA Abbe condenser is mounted on a rack-and-pinion control system, can be adjusted to control the distance of the light from the stage, and has an iris diaphragm to optimize the amount of light illuminating the specimen. The double-layer mechanical stage, with 1mm stage divisions, locks the slide into place and provides precise slide manipulation along the X- and Y-axis to allow coordinates to be recorded, enabling the viewer to return to a specific location on the slide. A stage stop prevents the stage from coming into contact with the slide and objectives. The stage is 5-1/2 x 5-1/2 inches (140 x 140mm) and has a traveling range of 2-15/16 x 1-3/4 inches (75 x 45mm). Graduated coaxial coarse and fine focus has a focusing range of 1-3/16″ (30mm) and fine-focus divisions of 0.002mm (0.0000787″) that enable measurements to be taken. Focus knob tension control prevents the stage from drifting out of focus. The solid-metal enamel-coated body is durable and resistant to stains and corrosion.

Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

The AmScope SE305-PZ stereo microscope has interchangeable pairs of 10x18mm and 20x10mmwidefield eyepieces, 1x and 3x objectives, upper and lower halogen lighting, a darkfield condenser, two stage plates, and a pillar stand. The binocular viewing head has an interpupillary range of 55 to 75mm and a 45-degree inclination to ease viewing for young users. The WF10x18mm and WF20x10mm eyepieces combine with the 1x and 3x objectives to provide 10x, 20x, 30x, and 60x magnification, and a longer working distance for inspecting large-scale specimens that require handling or repair. The optical glass lenses provide sharp images, and are fully coated to ensure high-resolution images. Dioptric adjustment accommodates individual eye-strength differences, and eye guards ensure comfortable viewing. A stereo microscope, sometimes called an inspection or dissection microscope, has low magnification and a long working distance that enables users to manipulate the object being inspected.
The microscope has upper (episcopic) illumination that reflects light off the specimen for enhanced visibility of opaque specimens, and lower (diascopic) Brightfield/Darkfield (BF/DF) illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background, and Darkfield (DF) illumination reflects light off the specimen, resulting in a light image on a dark background. The 10W halogen light source provides bright light in a concentrated path. The pillar-style stand secures the head for precise focusing, and bilateral coarse focus eases use for left- and right-handed users. The stage has a frosted stage plate for use with lower (transmitted) lighting, and a reversible black and white stage plate that provides contrast with light- and dark-colored specimens when used with upper (reflected) lighting. Stage clips that secure the specimen during viewing. The microscope has a 2-1/8″ (53mm) working distance. All metal construction is durable and stain-resistant.

The microscope has lower (diascopic) Brightfield illumination that transmits light up through the specimen for enhanced visibility of translucent and transparent objects. Brightfield (BF) illumination allows the specimen to absorb light, resulting in a dark image on a light background. Tungsten (incandescent) illumination provides bright light, and a rheostat controls the amount of light emanating from the lamp. The 1.25 NA Abbe condenser can be adjusted to control the distance of the light from the stage and has an iris diaphragm to optimize the amount of light illuminating the specimen. The condenser is controlled using a spiral mechanism. The plain stage has clips to secure the specimen in place, and is 4-3/8 x 4-3/4 inches (110 x 120mm) (W x D; where W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back). Separate coaxial coarse and fine focus eases focusing for left- and right-handed viewers, and a rack-and-pinion mechanism provides precise and secure focusing. Focus tension control prevents stage drift. All the mechanical parts of the microscope are constructed of metal to provide durability and resistance to wear.

Giant 70mm objectives gather a serious amount of light (twice as much as 50mm objectives)- so these are ideal for astronomy. In fact we consider the 11×70 to be the largest and most-powerful binocular that can be hand-held for astronomical viewing. They are also excellent for nautical applications and surveillance. Includes our latest low-reflection broadband multi-coatings, for highest-possible light transmission. Light loss due to reflection and scattering is minimized, providing the highest level of efficiency possible. The view is very close to Fujinon FMT-SX series quality, for a fraction of the price. New “slow-focus” provides precise focus control that won’t drift. Both offer long eye relief (especially the 11x model), so they work well with eyeglasses (the rubber eyecups fold down). All Oberwerk binoculars have rugged rubber-armored metal bodies, all-glass lenses, right ocular diopter adjustment, brass 1/4-20 tripod adapter threading, case, caps, and our premium heavy-duty strap. Truly an incredible value for only $149.95.
Dependable, solid, and powerful – this is the hallmark of the C Series. Offered in 10x and 12x magnifications, the C.3 features a large 50mm objective lens with crystal clear extra low-dispersion (ED) glass, fully multi-coated lenses, and a durable, yet lightweight polymer frame. At 28 ounces, the C.3 is one of the lightest mid-sized binoculars in its category. This dynamic mid-range binocular utilizes the same dielectric coated Schmidt-Pechan prism system that can be found in our B.1 and B.3 binoculars to produce an exceptionally clear, bright, and high-contrast image. Waterproof, fogproof, and scratch resistant lens coatings will ensure unimpeded field use. Rest assured, this workhorse will deliver when you need it most. Includes neoprene neckstrap, lens caps and double-layered microfiber storage bag.
Not all binoculars are created equal, especially when they are expected to perform well in low light conditions. Observations during twilight and at night require larger optics to collect as much light as possible, but big lenses alone are not enough to ensure a superior viewing experience. It also takes quality glass and rugged construction to keep your binoculars safe and working well for years to come. Celestron’s large-aperture Echelon series binoculars were designed for use in low light conditions. Whether you are long-range glassing across a field or valley, or gazing at the splendors of the Milky Way, a pair of Celestron Echelon binoculars will get the job done. With an exit pupil of 3.5 mm, these binoculars deliver an amazing amount of light allowing you to see the most detail possible. The Echelon 20×70 model offers the highest magnification in the Echelon Series. Choose this model for picking out small subjects at the longest distances, or for high-magnification viewing of celestial objects. Superb Optical Quality – Celestron Echelon binoculars sport high quality 70 mm objective lenses made in Japan. Superior BaK-4 prisms were chosen for maximum contrast and sharpness, and all air-to-glass surfaces are multi-coated with Celestron’s proprietary XLT optical coatings—the same high transmission coatings used on our observatory-grade telescopes to increase contrast and resolution. Assembled in the USA – Celestron Echelon binoculars are manufactured using quality Japanese optics and are assembled by hand by skilled technicians in Southern California. Quality Construction – Each Echelon binocular housing is made of aluminum alloy, to keep them strong yet lightweight, an important factor when considering a big binocular purchase. Durable rubber armor covers the aluminum housing for a slip-free grip and protection against the occasional bump or ding. These binoculars are fully waterproof and are nitrogen-purged to seal the optics against fog, dew, and other forms of moisture. This means you can use your Echelon binocular in damp conditions without having to pack up and call it a day when unexpected weather makes an appearance. Includes Waterproof Hard Case – Echelon binoculars come with a high quality waterproof hard case for ultimate protection against dust, moisture, and rough handling. A molded foam insert cradles the binoculars perfectly, keeping them safe and sound no matter where your journeys take you! Individual Focus – Echelon binoculars use an individual eye focus system, enabling you to rotate each eyepiece to set the proper focus for your right and left eye. Once set, you should be able to use your binoculars at a moment’s notice and focus sharply at infinity, the normal distance desired for long-range observations. Should you wish to share your binocular with others, it is fast and simple to adjust the focus for their vision requirements. Extended Eye Relief – The Celestron 20×70 Echelon Binoculars have 19.5 mm of eye relief, making them comfortable for all users, whether they wear eyeglasses or not. The rubber eyecups position your eyes at the perfect distance from the optics for a full field of view. Tripod Adaptable – Echelon binoculars are easily attached to a photographic tripod for extended observing sessions. A binocular tripod adapter (sold separately) is used to make the connection between the binoculars and a standard tripod, and is especially helpful for vibration-free observations of the night sky.
