Dichroic Mirror Source

Hi All,

I need 2 dichroic mirrors to combine my RGB lasers, 638nm, 520nm, 450nm respectively. Ideally I want the red to be combined last to reduce the losses. I don't really want to buy from Thorlabs or any other laboratory suppliers. I used to get them from DTR in the projector optics bundle but I need a new set for a new project. Any suggestions would help.

Also would like to find a small right angle prism.

Thanks!

You can get them for cheap at ebay

For your right angle prism, Lasertack.com sells small R,G, or B first surface mirror prisms, if that is what you are looking for.
