Product Description
Features
AR Coated for the 400-700nm & 1050 - 1700 nm Wavelength Range
Positive Doublet Sizes: Ø5 mm, Ø6 mm, Ø6.35 mm, Ø8 mm, Ø1/2", Ø1", Ø30 mm, and Ø2"
Focal Lengths from 7.5 mm to 1000 mm
Edge Blackening Available Upon Request
Our cemented IR Achromatic Doublets, which are optimized at infinite conjugate ratios, are designed to work in the telecommunications region (1050 - 1700 nm). With design wavelengths at 1016 nm, 1330 nm, and 1550 nm, these achromatic doublets are useful for controlling chromatic aberration. They can also be used to achieve a diffraction-limited spot when using a monochromatic source like a laser.

Detailed Images
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 is far superior to a simple lens for multi-color "white light" imaging. The two elements composing an achromatic lens (literally, "a lens with no color") are paired together for their ability to correct the color separation inherent in glass. Having eliminated the problematic chromatic aberrations, an achromatic lens becomes the most cost-efficient means for good polychromatic illumination and imaging.
Our Company
Wuhan Especial Optic is a leading manufacturer of high precision optics, which was established in 2012 and complied with ISO 9001:2015.
WHEO has around 60 sets of manufacturing equipments including lapping polishing machines, high-speed polishing machines, low-speed polishing machines, coating machines and advanced testing instruments including Interferometers, Spectrophotometers, precision goniometers and digital micrometers etc.
Our products are not limitted to optical windows, mirrors, lenses, prisms and filters, we can also custom fully new optics upon customers' unique demands. Furthermore, we have extensive expeience in manufacturing of ultra-high precision, ultra-large size, ultra-thin Infrared optical components. Now we're in small mass production of polygon scanning mirrors for several well-konwn companies in LiDAR and automation industries.
We always uphold a philosophy: your satisfaction is our eternal pursuit! We will make continuous efforts to provide customers with stronger, better and more perfect services.
