Product Description
An achromatic lens, often called an achromat, is a type of optical lens capable of correcting chromatic aberration, a distortion that occurs when glass splits white light into multiple colorwavelengths in the spectrum.
Chromatic aberration is a common type of imaging defect. When white light passes through a singlet lens, the wavelengths of light are refracted. Because different wavelengths pass through the glass at different rates, they come into focus at different points on the plane. As a result, the operator will not be able to bring all the colors into focus simultaneously. Chromatic aberration creates blurry fringes of color between dark and light parts of an image, significantly reducing image quality.

As a result, the operator will not be able to bring all the colors into focus simultaneously. Chromatic aberration creates blurry fringes of color between dark and light parts of an image, significantly reducing image quality.
Because achromatic lenses bring colors into focus at the same point, they allow users to fully focus an image. Compared to non-corrected singlet lenses, achromats produce much clearer images, which make for easier viewing and a more accurate perception.
When they were first introduced, achromatic lenses brought revolutionary changes to the way we do imaging. Though lenses have continued to improve in quality, the achromatic lens remains a staple in scientific and non-scientific optics applications.

- Improved image quality: By eliminating color fringes, achromatic lenses significantly increase image brightness and clarity. This fact is particularly true for polychromatic imaging.
- Efficient light transmission: Unlike singlet lenses, the on-axis performance of an achromatic lens won't degrade as aperture size increases, allowing you to utilize the entire clear aperture.
- Cost-effective production: Though improvements on the achromat exist, these lenses are much more expensive. For most purposes, an achromatic lens provides plenty of correction, making it the most cost-effective way to get clear white light images.
Right-angle Prisms, Corner Cube Prisms, Wedge Prisms, Roof Prisms, Dove Prisms, Polygon Prisms, and more. Our custom anti-reflection and reflection coatings cover wavelength ranges including UV, UV-VIS, VIS, VIS-NIR, SWIR, MWIR, LWIR, and multiple laser line options. On our site you will also find Precision Prisms with arcsecond angle tolerance which are designed to meet the most demanding needs in systems that require critical alignments. This includes precision imaging displacement systems, projection systems, and beam combiner systems.
To produce the desired color-correcting effect, achromatic lens manufacturers must use two or more types of optical glass with different amounts of wave dispersion. Typically, this process involves a concave lens element with high dispersion and a convex lens element with low dispersion. The two lenses are attached so that the distortion of one lens closely counteracts the distortion of the other. This type of achromat, called an achromatic doublet, is the most common, though triplet lenses exist as well.
