Product Description

Product Description
 
Coated 400~700 Nm Optical Glass Cemented Achromatic Doublet Lens
 
Coated 400~700 Nm Optical Glass Cemented Achromatic Doublet Lens
Achromatic lenses, usually consisting of two optical elements cemented together.It is the most cost-effective lens for good polychromatic illumination and imaging. Achromatic are excellent focusing components for reducing chromatic aberration of broadband light sources used in many analytical and medical devices. 
 

What Makes Achromatic Lens Important?

Achromatic lenses focus colors at the same point, allowing the user to focus on the image. Compared to uncorrected singlets, achromatic lenses produce sharper images, making viewing easier and perceiving more accurate.

They revolutionize the way you image. Despite the ever-increasing quality of lenses, achromatic lenses remain a staple for scientific and non-scientific optical applications.

Anatomy of an Achromatic Lens
An 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. In comparison to a singlet lens, or singlet for short, which only consists of a single piece of glass, the additional design freedom provided by using a doublet design allows for further optimization of performance. Therefore, an achromatic lens will have noticeable advantages over a comparable diameter and focal length singlet.
An achromatic lens comes in a variety of configurations, most notably, positive, negative, triplet, and aspherized. It is important to note that it can be a doublet (two elements) or triplet (three elements); the number of elements is not related to the number of rays for which it corrects. In other words, an achromatic lens designed for visible wavelengths corrects for red and blue, independent of it being a doublet or triplet configuration.  Refer to Figures 1- 4 for illustrations of each type.

Besides the basic processing equipments for optical components, such as the raw material cutting machines, milling machines, fine grinders, polishers, etc., Oplens uses the single point diamond turning machine (SPDT) for highly accurate optical lenses with nanometer scale surface accuracy and dimensional accuracy.

Oplens equipped Precitech SPDT with Taylor Hobson PGI 3D profilometer. The results of the profilometer measurement system can be directly put into the diamond machine to provide positive compensation values for the machining of aspheric components. At the same time, curvature, surface flatness, roughness and other indicators can be quantified effectively and accurately.
