Buying Cold Mirrors

Cold mirrors reflect visible light while transmitting or absorbing infrared light. They are used to reduce the heat load on an optical system caused by infrared light from a lamp, such as in projectors and illumination systems.
Making Good Purchase Decisions
RP Photonics helps you to not only to find all relevant suppliers, but also to make good purchasing decisions.
NEW: Structured Decision Process
We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.
(Various further improvements of this feature will come soon.)
