Home / Custom / Optical Components / Optical Spherical Lens / Custom Hyper Hemisphere Lens 
Custom-designed hemispherical lenses are special lenses designed and manufactured to meet specific application requirements, with a sphere that exceeds the standard hemispherical shape (i.e., the center thickness is greater than the radius of curvature). ECOPTIK is good at special shape and high-precision processing, and design processing flow according to customer's drawings and specifications.
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.
Precisely hemispherical. The machining precision of the center and radius of curvature of the sphere is extremely high.
The surface is precision polished to an optical grade of 10-5 to ensure image quality and reduce scattering and aberrations.
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.
