Positive Meniscus Lenses
Positive meniscus lens series; select the required material.
Compare K9 GLA15, UV fused silica GLA25 and germanium GLH92 positive meniscus lenses. Start with the material and required positive focal length, then check the curved-surface geometry and thickness against your design.

Choosing Positive Meniscus Lenses
- Choose the material branch for the operating wavelength and required coating.
- Compare radius, center thickness and usable aperture with the prescription rather than matching only focal length.
- For a replacement, identify the incoming-light side and provide the object and image geometry or original drawing.
Use the optical-parameter guide to distinguish focal, aperture and surface specifications.
