The PEAK TS2051-060 pocket-size 60x non-measuring microscope has a 3.5mm (0.140″) field of view and is used to view and inspect objects in field, lab, and quality control applications. The clear acrylic base and high-resolution glass lens and provide maximum light and high-quality images. The aluminum base provides durability for field, lab, and classroom applications. The microscope weighs 4 oz. and is 6 x 1.1 inches (H x W). (H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right.)

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.

PEAK produces optical glass and equipment such as microscopes and loupes. The company, founded in 1950, is headquartered in Tokyo, Japan.
