カスタム設計の半球面レンズは、特定の用途要件を満たすように設計・製造された特殊レンズで、標準の半球形状を超える球面形状（中心厚が曲率半径より大きい）を備えています。ECOPTIKは特殊形状と高精度加工を得意としており、お客様の図面と仕様に基づいて加工フローを設計します。
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.
