What kind of optics are these?

In summary, Bobby got these filters for a couple dollars at an electronics flea market. They look like they might be used in a HeNe laser, but he doesn't know for sure. He would be grateful for anyone who could help identify them.

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!
 

1. What are optics?

Optics is the branch of physics that deals with the behavior and properties of light, including its interactions with matter and the instruments used to detect it.

2. What are the different types of optics?

The different types of optics include geometric optics, physical optics, and quantum optics. Geometric optics deals with the behavior of light as rays, physical optics focuses on the wave-like nature of light, and quantum optics studies the interaction of light and matter at a subatomic level.

3. What is the difference between convex and concave lenses?

Convex lenses are thicker in the middle and thinner at the edges, causing light rays to converge. Concave lenses, on the other hand, are thinner in the middle and thicker at the edges, causing light rays to diverge. This difference in shape results in different properties and uses for each type of lens.

4. What are the applications of optics?

Optics has a wide range of applications in various fields such as medicine, telecommunications, astronomy, and photography. It is used in the design of lenses, mirrors, microscopes, telescopes, and other optical instruments.

5. How are optics used in everyday life?

Optics is used in everyday life in many ways, such as in eyeglasses, cameras, projectors, and laser pointers. It also plays a role in the technology used for digital displays, barcode scanners, and fiber optic communication systems.
