Astro-Physics Maxbright 2" Mirror Diagonal

The 2-Inch MaxBright Diagonal by Astro-Physics is designed with several unique features to provide optimum performance and years of use. Dielectric Coatings The Astro-Physics 2-inch diagonal has a very high-tech dielectric coating that was developed originally for military optics used in hostile environments such as blowing desert sand. There is no aluminum or other reflective metal used. The reflective surface consists of multiple layers of thin film oxides, similar to those used in anti-reflection coatings. The coatings are deposited using a sophisticated low-stress deposition method. Advantages of the Astro-Physics Dielectric Coatings: Reflectivity -Reflectivity is above 99-percent over the entire 400 to 700 nm photo-visual range. Thin film coatings have extremely low surface scatter compared to aluminum or enhanced aluminum coatings. Dielectric coatings (if done right) will result in less scattered light. Examination with a laser source shows approximately a 5 fold reduction in s
