Achromatic Lens

 
An achromatic lens is a lens that corrects chromatic and spherical aberrations by combining two convex and concave lenses with different refractive indices. Depending on the conditions, it is also possible to satisfy the Marechal criterion (less than 0.07ƒÉ RMS à no aberration).

Our achromatic lenses have a lineup of two types of anti-reflection coatings.

If you require different design wavelength or outer diameter, please contact us. For the coating simulation data and the price, please contact us.
