The AmScope SM-4TZ-FRL professional trinocular stereo zoom microscope has interchangeable pairs of 10x and 20x super-widefield high-eyepoint eyepieces, a 0.7x-4.5x zoom objective, two Barlow lenses, and a double-arm boom stand. The microscope has an overall magnification range of 3.5x-90x. The trinocular viewing head has an interpupillary range of 55 to 75mm, a 45-degree inclination to reduce eye and neck strain, and 360-degree rotation to enable sharing. The vertical trinocular port can be used as a C-Mount or 23mm photo port (camera sold separately). The WH10x20mm and WH20x10mm super-widefield high-eyepoint eyepieces combine with the 0.7x-4.5x zoom objective to provide continuous zoom magnification and a longer working distance for inspecting large-scale specimens that require handling or repair. The microscope comes with 0.5x and 2.0x Barlow lenses that can be added to the objective to increase the magnification range. A Barlow lens with a magnification of less than 1.0 reduces magnification and increases the working distance, while a Barlow lens with a magnification greater than 1.0 increases the magnification and reduces the working distance. High-eyepoint eyepieces ease viewing for users who wear glasses, and dioptric adjustment accommodates individual eye-strength differences. 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 removable 8W fluorescent ring light provides cool, white light for observing specimens as they would appear in their natural environment. A ring light provides shadow-free illumination. It has a 2-3/8″ inner diameter and uses a 110V-120V power supply. The microscope has a double-arm boom stand that enables users to position the microscope head on all three axes (X, Y, and Z). Bilateral focus eases use for left- and right-handed users. The stand has 20″ double arms, and a 30″ overall length. The pillar is 17″ and the focus rack has a 3″ diameter. The solid cast-steel base is 2 x 8-1/4 x 10-1/4 inches (H x W x D, where H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back).

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.

Features double stacked H-alpha etalon filters, one internal and one external, .5A bandpass, for outstanding surface detail. Used around the world by serious solar enthusiasts and professional research facilities alike for observation of surface detail and prominences on the Sun in hydrogen-alpha (Ha) light. Powerful but very portable, this high resolution Solar Telescope offers dedicated visual observation of the Sun as well as high quality imaging. The new Meade Coronado II represents a breakthrough in solar observing with the new and revolutionary RichView tuning assembly. This patented system allows direct tuning of the primary filter etalon. No other commercially available Ha telescope can provide the tuning range and accuracy of the SolarMax II. Now you can tune for the highest contrast views of active regions, flares, filaments, and other surface detail, or quickly and easily re-tune for prominences on the solar limb. This fully integrated double stack system has the added advantage of being able to operate at a less restrictive Less Than .7A bandwidth by simply removing the external etalon. In this way image brightness is increased, enhancing the visibility of fainter limb detail. The stunning bright red views through a Coronado Ha telescope display astounding surface and limb detail especially when the Sun is in an active phase. The sun

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). A mechanical specimen holder can be added to the plain stage to provide precise movement, perform measurements, and record coordinates. 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. The metal frame has a stain-resistant enamel finish for durability and to ease cleaning.
