The PZMIV is available in a binocular or trinocular version. In addition, an extensive list of optional accessories is available that makes the PZMIV suitable for integrated optical and biological research.
The microscope comes with a track stand, standard 10x eyepieces (wide-field, distortion-free and high eye point), 1x planachromatic distortion-free objective.
See the specification tables marked areas for more details. On trinocular versions of the microscope with the LWD option, the camera view is nearly the same as the eyepiece visual field of view.
The trinocular version 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.
Microscope objective and eyepieces work together. See Understanding Microscope Objectives.
