Objective lens 20/0.40, 160/0 for new Delta Stage

No I do not, they are completely non-descriptive and I don’t have any documentation from the original equipment it came from. Is there a way to tell without checking with zooming in and out? At the moment I don’t have any detector yet, and all similar equipment at work is static, so can’t change the magnification.

The objectives came out of scopes to inspect the end face of fiber optic connectors.

Ow, and thanks for answering my question!
