Description

The PAC12AR.15 Broadband Achromatic Lens is a 345 nm to 700 nm anti-reflection coated, 0.49 inch (12.5 mm) diameter, N-FK5 and F2 achromatic doublet lens with an effective focal length of 40.0 mm. This achromat is computer optimized to provide diffraciton limited performance for polychromatic illumination applications in the 345 to 550 nm spectral range. It is the idea choice for fluorescence applications, UV light source applications, UV LED’s, and Nd: YAG lasers. Spherical and chromatic aberrations are minimized to provide superior performance.
