H-K9L positive meniscus lenses

Introduction

Product description

material：H-K9L
Design wavelength：632.8nm
Effective aperture：90%

Lenses usually refers to the optical elements that diverge or converge the beam of light. Lenses have been widely used in security, vehicle-mounted systems, digital cameras, lasers, and optical instruments, while playing an important role in astronomy, military, transportation, medicine and other fields. OMTOOLS provides or customizes positive and negative lenses for different bands, with different focal lengths and apertures made of K9, fused silica and other materials (including plano-convex, biconvex, meniscus, plano-concave and biconcave) for diversified commercial and scientific uses.
