The Leica optics ae designed to produce high resolution, high contrast images of the sample.Using a Greenough-based optical design that produces a flat image field (planar correction), optimal color transmission (chromatic correction) and allows more of the specimen to be in focus at once (depth of field).
The Leica S8APO offers a 8:1 Zoom Ratio, with a magnification range of 10X - 80X. The S8APO also offer a field of view and working distance, 23mm which reduces the need for sample handling. The working distance is 75mm, from microscope to specimen, providing space for any manipulation if required.
For ease of use the S8APO comes with a ergonomically designed 38 degree viewing angle, and adjustable upper and lower zoom magnification stops. The eyepieces are suitable for eyeglass wearers, furthermore the microscope is coated in Leica's 'ZeroStat' polymers to protect agains electrostatic discharge (ESD).
