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/8 wave first surface mirror glass offers a superior quality compared to other first surface mirrors on the market. λ/8 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/8 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.

Testing

Our high quality optics are tested with an interferometer, which is a piece of equipment that is designed to be able to test a multitude of different shape optics (flat and curved). Flat optics have an advantage hat they can be tested utilizing a Master Optical flat, which is a propitiatory in-house process that allows testing of different areas of the mirror. The mirror is then measured at those areas and analyzes the areas that are most deviant from flat. As a result, the mirrors will typically be better than what is reported. 1/4″ glass can bend under its own weight, so all tests are performed with the mirror under minimal stress, supported so the glass is not bending under its own weight.

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.
