Greetings,
I have a 30X beam expander. Am I correct in believing this device will concentrate a laser beam to 30 times it's power with a focused spot 30 times smaller than the original beam?
Are expanders built for different frequencies? If so how could I determine the frequency my expander was designed for?
I have some mounted mirrors. When held up to the light you can see through them (violet color). Are these mirrors? Are they beam splitters? Are they filters?
Thank You in advance for your responses.
