What Makes Achromatic Cylindrical Lenses Important?

Because achromatic cylindrical lenses focus colors at the same point, they enable users to focus on an image completely. Achromatic cylindrical lenses produce clearer images than uncorrected singlet lenses, making them easier to observe and more accurate to perceive.


When achromatic cylindrical lenses were first introduced, they brought about revolutionary changes in imaging methods. Although the quality of lenses is improving all the time, achromatic cylindrical lenses are still the main application in scientific and non-scientific optical applications. Some of the advantages of achromatic cylindrical lens assemblies are listed as follows.


Ⅰ. Achromatic cylindrical lenses can improve the image quality


Achromatic cylindrical lenses eliminate ribbons and greatly improve the brightness and sharpness of images. This is especially true for polychromatic imaging.


Ⅱ. Achromatic cylindrical lenses have efficient light transmission


Unlike singlet lenses, the coaxial performance of achromatic cylindrical lenses does not decrease as the aperture size increases, allowing you to utilize the entire transparent aperture.


Ⅲ. Achromatic cylindrical lenses are cost-effective to produce


Although achromatic lenses can be improved, they are much more expensive. For most purposes, achromatic cylindrical lenses provide a large amount of correction, making them the most cost-effective method of obtaining clear white light images.


To produce the desired color correction effect, manufacturers of achromatic cylindrical lenses must use two or more types of optical glass with different amounts of wave dispersion. Generally, the process involves a concave lens element with high dispersion and a convex lens element with low dispersion. Two lenses are installed so that the deformation of one closely cancels out that of the other. Such achromatic cylindrical lenses are called achromatic binaries and the most common type of achromatic cylindrical lenses, although triplets also exist.


Achromatic cylindrical lenses minimize chromatic aberration and can therefore be used to focus multicolor beams in a single direction. Unlike spherical lenses, which produce spot-focused spots, achromatic cylindrical lenses can produce linearly focused spots. For ease of use, Ecoptik cylindrical achromatic couplets are preinstalled in a 1-inch housing. The housing is engraved with the part number, the range of projected film to be added, the focal length, an arrow indicating the direction the lens should face when a quasi-linear light source is used, and an infinite symbol indicating that the lens has an infinite conjugate ratio. As one of the professional optical component companies, Ecoptik Optics can provide a variety of achromatic cylindrical lenses. If you have requirements, please feel free to contact us!
