Product Description
This optical plano-concave lens is ideal for beam divergence, aberration correction, and optical path adjustment. Manufactured from materials such as H-K9L optical glass or fused silica, it combines high transmission with low scattering characteristics.
With surface accuracy up to λ/4 and 40-20 scratch-dig quality, the plano-concave lens helps reduce optical aberrations and improve system efficiency. Optional multi-layer anti-reflection coatings further enhance transmission performance across visible and near-infrared wavelengths, making it suitable for laser, inspection, and scientific optical applications.
