What kind of optics are these?

  1. Nov 13, 2012 #1
    I got these for a couple dollars at an electronics flea market. They look like maybe some kind of dichroic lens, but I don't know. Can anyone help identify them? Did I get a good deal for a couple bucks?

    Here's the first one. It's hard to tell from the picture, but it's got a slight red tint:

    The side has printed on it: 110-0006-RD CVI 211020

    Here's one side of the next one:

    And the other side:

    The top of the case has a sticker that says
    Continuum
    Part No:
    105-0022, Rev. F
    S/N: 2213+2214

    I don't know much about optics, but I have a HeNe laser and thought these might be fun to play with. I'd be much obliged to anyone who can help identify.

    Are they filters of some type? Is the clear plastic just the cases?

    Yeah, those are just the cases I got them in.

    They are likely dielectric filters- CVI is now part of Melles Griot, and they did a lot of optical coatings. An item similar to the last one turned up here:

    Was it a good deal? I guess that depends on if you think it was a good deal or not :) Have fun!
