Product Description

Product Description

 

Wholesale Good Quality Optical Glass Bk7 K9 Ar Coating Meniscus Lens

  

Meniscus lens is a lens which has two spherical curved surfaces, convex on one side and concave on the other side. It is thicker at the center than at the edges. The lens provides a smaller beam diameter in order to reduce the beam waste and spherical aberration. When a meniscus lens is combined with another lens, the focal length is shortened and the numerical aperture of the system is increased. This reduces the image distortion and increases image resolution. 

 

There are two types of meniscus lenses:

Positive meniscus lens

The positive meniscus lens is used for applications requiring small focal numbers (less than 2.5). For focal lengths between 2.5 and 10, a meniscus lens minimizes spot size and improves image quality. The concave side curvature of a positive lens is smaller and the convex side curvature is larger.

1. Frequently used for beam focusing applications

2. Minimizes the increase in spherical aberrations for multi-element systems

Negative meniscus lens

The negative meniscus lens is used for applications using infrared materials with a high refractive index. These lenses serve as substitutes for other negative lenses with greater curvature on the concave side and less curvature on the convex side. They are used in beam spreading applications where minimal spherical aberration is required.

1. Frequently used for beam expanding applications

2. Minimizes the increase in spherical aberrations for multi-element systems

Company Profile

 

Oplens (brand own by SiChuan JUKA Optical Technology) is located in the city of Chengdu, China, which enjoys the reputation of the world optical processing center. Oplens has been committed to providing customers with high-precision optical system solutions over 16 years, covering the complete manufacturing process from the design, processing and assembly of various optical components and mechanics.

It occupies 10,000 square meters of modernized facilities with hundreds of equipments and instruments. More importantly, Oplens owns an excellent team of more than 200 experienced engineers and workers, who provide the best products and service to their both domestic and overseas customers.

 

Processing

 

 

Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.
