Hi all!
I recently came across a listing of second hand beam expanders for a good price on a Chinese ebay-like site. They are used but are in good condition; no scratches on the lenses and only minor cosmetic damage to the anodizing. The seller is offering ten or so for sale, and so I purchased one for my holography interferometer setup and was wondering if anyone else on the forum is interested in buying one. If so I could buy a couple more and sell them for ~$90 each, which is a pretty good price for this specific beam expander and just a 10x beam expander in general. Please reply if anyone is interested.
The specific model number is Melles Griot 09LBX003, details as follows:
Below I have included pictures of the specific one I received.
Note in the last image the silver line is not damaged anodizing but rather a silver sharpie line used to line up the focusing ring to a specific focus in the previous application.
