Achromatic Doublet Lenses suppliers china tells you that, unlike glass elements, aspheric achromatic lenses have a narrow operating temperature range between 20°C and 80°C. Achromatic Doublet Lenses suppliers china tells you that this temperature range limits the possibility of using AR coatings on aspheric achromatic lens surfaces.

In addition, Achromatic Doublet Lenses suppliers china tells you that the material of the aspheric achromatic lens blocks the transmission of deep UV, making the lens unsuitable for some applications. While this lens is not scratch resistant, it is very cost-effective and easy to replace. All in all, this lens still has many advantages.
Achromatic Doublet Lenses suppliers china tells you that the production of aspheric achromatic lenses improves polychromatic light imaging. Achromats are far superior to simple polychromatic "white source" imaging lenses. The two elements that make up an achromat (literally "lens without tint") combine to correct for the chromatic aberration inherent in glass. Because of their ability to eliminate difficult chromatic aberrations, achromats are extremely cost-effective for polychromatic illumination and imaging.
Through the above introduction and analysis of the Achromatic Doublet Lenses suppliers china, hope it helps you.
