Spherical Positive Mensicus Lens

H-K9L Positive Meniscus Lens has excellent transmittance from visible to near infrared (350-2000nm).H-K9L (N-BK7) is a commonly used optical glass for the preparation of high-quality optical elements. When the additional advantages of UV melting quartz (good transmittance and low thermal expansion coefficient in the UV band) are not needed, H-K9L is generally selected.Positive meniscus lenses are designed to minimize spherical aberration and can be used alone to obtain a minimum converging spot, or when combined with another lens to reduce the focal length and thus increase the numerical aperture.For converging parallel light, the convex surface of the lens should face the source to minimize spherical aberration.


Spherical Negative Mensicus Lens

The H-K9L Negative Meniscus lens has excellent transmittance from visible to near infrared (350-2000nm).H-k9l (N-BK7) is a commonly used optical glass for the preparation of high-quality optical elements. When the additional advantages of UV melting quartz (good transmittance and low thermal expansion coefficient in the UV band) are not needed, H-K9L is generally selected.The central part of a negative menuscule lens is thinner than its edge, causing light to diverge and designed to minimize spherical aberration.They are often used in conjunction with other lenses to increase the focal length and thus reduce the numerical aperture (NA) of the optical system.When used for astigmatism, the concave surface should be oriented towards the beam to minimize spherical aberration
