This objective lens offers excellent optical quality. It has an anti-reflective coating, which significantly improves image quality.
This objective lens was originally designed for use in inverted metallurgical microscopes, but it can also be used in 170 mm biological microscopes (though many people use it in 160 mm microscopes).
What is this part needed for?
- If you have a Union microscope without objectives and need to upgrade it using original parts
- If you have a Union microscope that doesn't have an objective lens with this magnification and want to upgrade it
- If you have such an objective lens, but it's of very poor quality or damaged
- If you're cautious and want to have such an objective lens on hand
- If you're looking for a very good 5x objective lens for your microscope from another manufacturer
- If you're looking for a good quality lens with anti-reflective coating for macro photography
