Ecoptik China can process high-precision customized microlenses with a diameter of 1mm-10mm. It can involve a variety of materials in the ultraviolet, visible, and infrared wavebands. Such microlenses are the core components of multiple optical systems and are widely used in medical instruments, optical fiber transmission equipment, micro imaging systems, and so on.
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.
