AlSiO Economy Optical Mirrors

AlSiO economy optical mirrors provide a lower-cost alternative to ultra-high precision optical mirrors for applications that do not require premium flatness specifications. These mirrors are flat to approximately one wave per inch and use the same low-pinhole, long-lasting AlSiO protected aluminum coating used on higher precision mirrors.

Square, rectangular, and round economy optical mirrors are available in the stocked sizes listed below. Other sizes and custom options are available upon request. For unprotected aluminum mirrors, view our Bare Al Optical Mirrors.
