The FAC 200 from FISBA is a Fast Axis Collimator (FAC) Lens that operates at wavelength ranges of 790 nm - 990 nm and 750 nm - 850 nm. It has a numerical aperture of 0.8, focal length of 200 μm (at 808 nm & 940 nm), and back focal length of 54 μm (808 nm) & 55 μm (940 nm). This lens has a residual divergence of ± 3 mrad (at 85 % power enclosure) and refractive index greater than 1.8. It measures 0.33 (H) mm x 0.27 (T) mm and has a length of 2 mm - 20 mm. This lens is ideal for diode laser systems, fiber laser pumps, disk laser pumps, solid-state laser pumps, and LiDAR systems applications.
