AmScope PA100X-IRIS 100xS (Spring, Oil) Darkfield Objective with Internal Iris, Plan Achromatic, 20mm DIN/JIS Mounting Standard

• 100xS (spring, oil) darkfield objective
• Plan achromatic objectives with internal iris diaphragm
• 20mm mounting size DIN/JIS

The AmScope PA100X-IRIS 100xS (spring, oil) Darkfield microscope objective has plan achromatic coatings to provide color correction and improved focus over the entire range of the viewing field, and an internal iris to increase image contrast in Darkfield microscopy. The 100xS (oil) objective is spring loaded to prevent slide damage when focusing, and is designed to be used with a drop of oil between the objective and the slide to provide increased resolution over a standard objective. The objective has a standard 20mm DIN/JIS mounting thread.

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. United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.
