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.
Back Reflector Applications
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.
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.
