75K00ER.3 Utility Broadband Aluminum Mirror
The 75K00ER.3 is a Utility Broadband Aluminum Mirror optimized for 400-10,000 nm with square dimensions of 190.5 x 190.5 mm and a 5.84 mm thickness.
These mirrors are excellent economical broadband reflectors. The front surface is coated with our ER.3 dielectric-enhanced aluminum coating. The 75K00ER.3 has an average reflectivity greater than 90% from 400-2000 nm. These mirrors can be used as a front or back surface reflector. A removable plastic sheet protects the mirror surface during shipment and handling, and can be left on if used as a back surface reflector.
