Features
Low Cost Float Glass Substrate
Float glass is made by floating molten glass over a bed of molten metal. While this is a low cost material that is used in commercial windows, the production method yields a very flat surface of uniform thickness making it a good choice for optics. For more information, refer to the optical material technical note.
Enhanced Aluminum Broadband Metallic Coating
The front surface is coated with our ER.3 dielectric-enhanced aluminum coating. Average reflectivity is greater than 90% from 400-2000 nm typically.
Front or Back Reflector Applications
These mirrors can be used as a front or back surface reflector. A removable plastic sheet is attached to the coated surface to protect the mirror surface during shipment and handling. It can be left on if used as a back surface reflector or removed if used as a front surface reflector.
