Meniscus Lens
Meniscus lens is divided into positive and negative lunar lenses.One side of a meniscus lens is convex and the other side is concave. It can be a convergent lens or a divergent lens, determined by the refractive index, curvature, and radius together. Widely used in photography systems, projection systems, imaging systems, optical viewfinder, and laser measurement systems.

Types of Meniscus Lenes
Positive Meniscus Lens:

This lens is used in applications requiring a short focal length (typically less than 2.5). For focal lengths between 2.5 and 10, positive meniscus lenses are ideal for reducing spot size and improving image quality. In this type, the concave surface has a smaller curvature (less steep), and the convex surface has a larger curvature (more steeply curved).



Negative Meniscus Lens:

These lenses are suitable for use with high-refractive-index infrared materials. They serve as an alternative to conventional negative lenses with steep concave surfaces and shallow convex curves. Negative meniscus lenses are commonly used in beam expansion systems where minimizing spherical aberration is critical.

Meniscus lenses have positive meniscus lenses and negative meniscus lenses, they are used in telescopes, camera, collimators, laser systems.

Hanzhong Brisun Optics Co., Ltd. Is the high High precision optical element manufacturer provides customized production of Various optical lenses, including spherical lens, cylindrical lens, optical window, mirror, prism, filter, metal base mirror and other high-precision optical elements. The base materials include various optical glass, fused quartz, calcium fluoride (CaF2), zinc selenide (ZnSe), germanium (GE), silicon (SI), sapphire, metal and other materials. And provide antireflective film, high reflection film, spectroscopic film, metal film and other optical coatings.

Meniscus lens is concave convex lens. The lens has an outer convex mirror and an inner concave mirror. If the outward radian is greater than the inward radian, the lens has a positive focal length and is used as a magnifying glass.

Borisun optics technology provides meniscus lenses without coating and coated with IR3 antireflection film. Germanium (GE) substrates are suitable for infrared applications.

Optical Cylindrical lens
PARAMETER:
Meniscus Cylindrical Lens can increase the NA of the system while only adding slightly to the total spherical aberrations. The Negative Meniscus Lens is used to increase the focal length of another lens while maintaining the angular resolution of the optical assembly. This lens shape is best used when one conjugate is relatively far from the lens.
