Achromatic Lenses

Achromatic Lenses

Achromatic lens, also referred to as an achromat, typically consists of two optical components cemented together, usually a positive low-index (crown) element and a negative high-index (flint) element. Due to the difference in refractive indices, chromatic aberration with respect to two selected wavelengths has been corrected. The lenses have been corrected for on-axis spherical aberration as well. Achromatic doublets are used as telescope objectives, eye loupes, magnifying glasses and eyepieces. Achromatic doublets have also been used to focus and manipulate laser beams because their image quality is superior to single lenses.


CLZ Optical Co., Ltd. stocks Achromatic lenses ranging from 10mm to 250mm in diameter with a full range of focal lengths to meet your needs. We can also customize optical components to meet your requirements using a variety of optical materials, such as optical glass, fused silica, silicon.

We can modifying diameter of lenses and blacking edge in stock optics to meet your requriments.

This can achieve:

The stock optics diameter from large to small and tighter diameter tolerance.

Coated Area is a continuous coating  extending to the edges of the optical component. (Edge after coating)

Edge-blackened lenses, or inked lenses, minimize the stray light within an optical system.
