I would like to use your Off-Axis Mirror in a laser application with high temperatures. What is the maximum damage threshold and temperature limit these mirrors can withstand?

Unfortunately, our Off-Axis Parabolic Mirrors are not damage threshold tested. They are not intended for use with high power lasers.

Optical performance of the mirrors is limited by the maximum temperature at which 6061 Aluminum (the mirrors’ substrate) begins to stress-relieve. The surface figure may begin to change at this point. Damage to the coating may occur beyond 200° C, though we do not have tested data to validate this. In the case of our Aluminum coated Off-Axis Parabolic Mirrors, damage refers to oxidation and crystallization of the coating; whereas, for the Gold coated versions, damage refers to de-lamination of the coating from the substrate.
