Spherical Mirror

In practical applications, other parameters are also involved according to the specific use of spherical mirrors. These parameters often relate to the material, coating, and size of the spherical mirror. For example: 

Material: Such as BK7 optical glass, UV fused silica, calcium fluoride (CaF2), magnesium fluoride (MgF2), etc. These materials have good transmittance or reflectance in different bands such as visible light, ultraviolet, and infrared.

Coating: To improve the optical performance of spherical mirrors, multi-layer anti-reflection films or antireflection films are often coated on their surfaces to reduce surface reflection and increase transmittance or reflectance.

Size: Including diameter, thickness, etc. These size parameters can affect the imaging range and focal length of the spherical mirror’s optical properties.
