The OPTOMAN PCV-F75-UVFS-25.4-CT2.0-AR784-AR784 is a precision UVFS (JGS1) concave lens designed for ultrafast laser beam control at 515 nm. With a -75 mm focal length, 25.4 mm diameter, and IBS anti-reflective coatings on both surfaces, the lens provides very low reflection and high optical transmission for demanding femtosecond and picosecond laser applications.

Its optimized AR coating delivers less than 0.1% reflectance at 515 nm at normal incidence, while the lens maintains a surface quality of 20-10, surface irregularity below λ/6 at 633 nm, and an estimated laser-induced damage threshold above 0.25 J/cm² at 515 nm, 500 fs, 10 kHz. The UVFS substrate, low absorption, and low group delay dispersion make this concave lens suitable for applications where pulse integrity and beam quality are critical.
