Description

K9 Meniscus Lens is a classic precision optical lens made of high-quality K9 optical glass, designed with one convex surface and one concave surface. The unique meniscus profile effectively corrects spherical aberration, coma and chromatic aberration in optical systems. With high optical uniformity, low bubble and impurity content, excellent visible and near-infrared transmittance, K9 meniscus lens maintains stable imaging quality and light beam performance. It is widely used for light path correction, aberration elimination, beam focusing and collimation in conventional optical instruments, imaging systems and industrial optical assemblies.

Frequently Asked Questions

What is the main function of a K9 meniscus lens?
It is mainly used to correct spherical aberration and coma, optimize beam quality, and assist focusing and collimation in combined optical lens groups.
What is the difference between K9 meniscus lens and quartz meniscus lens?
K9 glass is cost-effective and excellent for visible imaging; quartz has better deep UV transmittance and higher laser damage threshold, suitable for UV and high-power laser scenarios.
Does K9 meniscus lens support anti-reflection coating?
Yes, it can be coated with customized AR coating for visible and near-infrared wavelengths to reduce reflectance and improve transmittance.
