Achromatic Doublet Lens
An Achromatic Doublet Lens               , also referred to as an achromat, typically consists of two optical components cemented together, The achromatic design also helps minimize spherical aberrations.  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 doublet lens will have noticeable advantages over a comparable diameter and focal length singlet.     
 
We can provide customized achromatic doublet lenses to meet your requirements or edge stock lenses for quick turnaround, please inquire.
 
Types of achromatic lenses
An achromatic lens is available in doublet (two components) or triplet (three components) configurations with round or cylindrical design options. High performance achromatic lenses may also have an aspherical surface for additional spherical aberration correction.     
 
Uncoated achromatic lenses and achromatic lenses with specific wavelength anti-reflection (AR) coatings. Uncoated achromatic lenses are typically designed for infrared (IR) and ultraviolet (UV) and offer superior performance compared to standard UV/IR coated achromatic lenses.
