Custom MgF2 Coated Achromatic Lenses
consist of two optical components cemented together to form achromatic doublet lenses.
provide custom achromatic doublets are available with a single layer MgF2 coating for the visible spectrum.
Our MgF2 coating can be less than 1.75% reflectance @ 400-700nm, AOI=0°. And we can produce that make up achromatic lenses according to customer requirements before cemented.
Achromatic doublet lenses Manufacturing Capabilities:
Diameter (mm): 6mm to 150mm, Tolerances: +0/0.02mm
Center thickness (mm) Tolerances:±0.025mm
Surface Power (fringes) : 3
Surface Irregularity (fringes, P-V @ 633 nm): 0.2 fringes
Surface quality (scratch - dig): 20-10
Centration (edge thickness variation, mm): 0.002mm
