I have three questions on materials:

 

 

1. What common materials are opaque to the infrared and/or the UV spectrum?
   
2. What common materials reflect all visible light except infrared and/or UV light?
   
3. What common materials are completely transparent to infrared and/or UV light?
   

 

They're all similar, so I thought I'd bundle 'em up in one post.

 

Note: By common, I mean available cheaply.

Bump.

 

Are mirrors transparent to the IR spectrum?

1. IR doesn`t like to go through Green or Blue lenses, UV doesn`t pass through regular glass very well.

 

2. no idea off the top of my head (maybe a blonde moment?)

 

3. clear Quartz will allow UV and IR to pass through.

 

 

I may think of some more later

I don't think any material is "completely" transparent or reflect "all" light.

 

I think Google is your friend for something like this.

also it would be a good idea to state which IR band, FAR IR is easily blocked by Perspex, but NEAR IR isn`t.

 

PVC sheeting (the clear stuff) lets quite a bit of UV through also (it`s great Greenhouse material) also for greenhouses is a type of film that you can buy that blocks alot of the IR but allows light (visible) to pass quite nicely, I think it`s Mylar based, but I`m not 100% on that.

 

Clear Quartz is your best bet for a "pass All" though, as used in Cuvetes.

What is clear quartz's refractive index?

 

[Edit: as far as what band, I'm not entirely sure. As soon as I find out, I'll let you guys know. By the way, what are Cuvetes?]

cuvettes are little tubes/vials used in IR and other spectrophotometric analysis. They hold the samples without interfering with the results.
