Optek ST8050-STL6

The ST8050 series was designed for demanding users.

For their price they have unusually bright optics and a large depth of field, excellent zoom mechanics with the widest range at 0.8x–5x, and a modular build that can be configured freely.

 

Worth particular note on this model:

* wide-field eyepieces with protective fold-back rubber eyecups, designed to work for people who wear prescription glasses

* the very wide zoom range makes magnifications from 4x to 200x possible (the modules are in our range)

* the graduated zoom knob tells you exactly what magnification the microscope is working at — which you have to know in order to measure

* the trinocular version (ST8050T) has a CS-Mount connector with a 0.5x factor (ST1/2CTV), which captures an image with a field of view comparable to what the eyepieces show.

* the advanced focusing system lets the resistance of the focus knobs be adjusted

* the head comes with a mount for a ring illuminator as standard, so any ring light can be fitted without special adapter rings

* the whole set assembles without tools
