Meniscus Lenses from ALHAZEN China: Top Suppliers and Factory for Positive and Negative Focal Lengths
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.
- Frequently used for beam focusing applications
- 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.
- Frequently used for beam expanding applications
- Minimizes the increase in spherical aberrations for multi-element systems
