Name: Micro Prism
Rating: 4.5 (100 reviews)

Key Features

Materials

Optical glass such as K9, fused silica, sapphire, MgF2, silicon (Si), ZnSe, ZnS, etc. These materials possess high transmittance, low absorption, low scattering, uniform refractive index, and specific dispersion characteristics.
Shape

Precisely hemispherical. The machining precision of the center and radius of curvature of the sphere is extremely high.
Surface Quality

The surface is precision polished to an optical grade of 10-5 to ensure image quality and reduce scattering and aberrations.
Coating

An AR coating is typically applied to the concave surface to maximize the transmittance of specific wavelengths of light (e.g. visible light) and reduce reflection loss.

Typical Application Areas

Underwater Photography and Detection:

Observation windows for underwater cameras, ROVs (Remotely Operated Vehicles), and AUVs (Autonomous Underwater Vehicles). The hemispherical design provides a near 180° wide field of view while withstanding water pressure.
