Achromatic Lens, Broadband, 25.00 mm, 60.00 mm EFL, 345-700 nm
The PAC16AR.15 Broadband Achromatic Lens is a 345 nm to 700 nm anti-reflection coated, 0.98 inch (25.0 mm) diameter, N-FK5 and N-F2 achromatic doublet lens with an effective focal length of 60.0 mm. This achromat is computer optimized to provide diffraction 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.
