I know this is a dumb questions, but what are IR filters made of?
I know that some companies (like Optotronics and NOVAlasers) sell IR filters that users can add to their lasers. However, IR filters often come in one large piece.
Are they generally made of glass or plastic? Glass optics are more resilient to scratches and other wear, but they also shatter to stress more easily. In that case, are there any safe methods for cutting an IR filter into smaller pieces?
