The fourth generation of WPI's trinocular precision stereo zoom microscopes uses modular, two parallel beam path design and high quality optical system.

• High-contrast imaging, ideal for observing transparent, low-contrast objects
• Long working distance option available
• Integrated optical and biological research
• Large zoom ratio of 8:1
• Large zoom range of 0.62× to 5.0×

This trinocular microscope is a true trinocular, with continuous operation of both eyepieces and photo tube simultaneously. There is no need to block the right eyepiece to use the photoport.

The advanced optical design with planachromatic objectives provides sharp and distortion-free contrast image throughout the entire zoom range and comes with an impressive five year warranty. The microscope offers planachromatic objectives the ensure no optical distortion.

The PZMIV is available in a binocular or trinocular version. The microscope comes with a track stand, standard 10× eyepieces (wide-field, distortion-free and high eye point), 1× planachromatic distortion-free objective. On trinocular versions of the microscope with the LWD option, the camera view is nearly the same as the eyepiece visual field of view.
