635nm red filter

This 635nm band-pass filter is renamed in order to meet the hobby of users. The majority of users, especially laser measurement and rangefinder users, do not have too high requirements for stray light, as long as they can filter 85% of the light. Therefore, this is suitable for semiconductor lasers and customized for instruments and equipment that do not participate in imaging. It can also be glued according to special customer needs or added with anode aluminum sleeve for special purposes.
