NOTE - Although this is a plan achromatic objective, it does not require dedicated plan compensation optics (e.g., special eyepieces). This makes it very popular for macro photography ? it has a 9:1 magnification ratio, no distortion at the image edge, and operates in direct projection mode.
What is this part needed for?
- If you want to upgrade your Lomo microscope with original parts
- If you need a 9x objective lens for a flat image for Lomo, Carl Zeiss Jena, PZO, IOR, or other microscopes requiring 33mm and 160mm lenses
- If you have a Lomo microscope from 1991 (the serial number begins with "91") and want lenses from that era
- If you're looking for an interesting lens for macro photography and photo stacking.
