Product Description

Custom optics are sometimes advertised as not only possessing high accuracy, but also as inexpensive; as if both were simultaneously achievable. In the world of optics, you get what you pay for. λ/4 wave first surface mirror glass offers a superior quality compared to other first surface mirrors on the market. λ/4 flatness is achieved by polishing float glass down to a flat surface, then coating with aluminum and the protective overcoat. Typically, what most of our competitors offer is simply on float glass, which is 4-6λ per inch. To the naked eye, the two mirrors look the same, but the quality of the λ/4 is immediately noticeable under magnification. The production of a high-quality optical component is an exacting process, requiring a high level of skill, quality equipment, and close attention to detail.

Frequently Asked Questions

The surface of the glass is polished using increasingly fine methods before coating. This creates a superior flatness compared to standard float glass, and eliminates various distortions such as draw lines.

We make sure the edges are sanded so they’re not sharp.
