Product Description
Achromatic double cemented lens consists of a positive lens with low refractive index (crown glass) and a negative lens with high refractive index (flint glass). This series of achromatic double cemented lenses have been optimized by computer in the visible light band (blue light/green light 486.1nm, yellow light 587.6nm and red light 656.3nm), and spherical aberration, coma aberration and chromatic aberration have been well corrected. The surface is coated with multi-layer antireflection films of 400-750nm, which has the best performance in the visible light band.
When used to focus collimated light, the convex lens or the surface with small radius of curvature faces the collimated light, and when used for imaging, the convex lens should face the side with longer object distance or image distance.
