Biconcave Lens

Biconcave Aspherical Lenses are commonly used to control beam divergence in laser applications, or for use in imaging and sensor systems where precise light shaping is required. Their aspherical design helps reduce spherical aberration, providing improved optical performance compared to traditional spherical lenses. Biconcave Aspherical Lenses feature optimized profiles to achieve efficient beam expansion and uniform light distribution.

1. What are Biconcave Aspherical Lenses?

 

Biconcave aspherical lenses are optical lenses featuring two concave surfaces with an aspherical profile. They are designed to effectively diverge light while reducing spherical aberration compared to traditional spherical lenses. Their optimized shape provides improved beam control and higher optical performance in compact systems.


2. What are the Biconcave Aspherical Lenses used for?


Biconcave aspherical lenses are commonly used in beam expansion, laser shaping, imaging systems, and optical instruments that require precise light divergence. Their ability to minimize optical distortion makes them ideal for high-precision and space-limited applications.


Features:


· Ideal for Beam Expansion and Divergence Control
· Reduced Spherical Aberration for Improved Optical Performance
· Available in a Variety of Sizes and Materials

Concave-convex Lens
Concave-convex aspherical lenses are commonly used to correct spherical aberration and improve imaging quality in optical systems, especially where high resolution and compact design are required. Their aspherical surface design enables better light focusing and reduced distortion compared to traditional spherical lenses. 
Dispersion Prisms
30° - 60° - 90° Littrow Dispersion Prisms
Dispersion Prisms are used in applications that require separating the incident light into its component wavelengths. For example, when white light enters a Dispersion Prism, it is separated into its three components: red, green, and blue. Dispersion Prisms are ideal for spectroscopy or laser tuning.
