Astro-Physics Maxbright 2" Mirror Diagonal


The Astro-Physics 2" MaxBright Diagonal is designed with several unique features to provide optimum performance and years of use.

Dielectric Coatings The Astro-Physics 2" 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% over the entire 4000 to 7000 Å 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 surface scatter, a tremendous improvement over aluminum mirrors.

Durability -The main advantage of a dielectric mirror coating (again, if done properly) is that the surface will be durable and will last for a lifetime. It will never tarnish and will be resistant to sleeks when cleaned.

Mechanical Features:

The diagonal is accurately square to the optical axis due to the CNC machined parts and special mounting method of the mirror. The baffles and flat black interior allow maximum contrast. It is threaded for 48 mm filters so that you can change eyepieces with ease without changing the filter.
