G313333525 22.4 mm Dia. UVFS Double-Concave Lens; EFL=-50mm
The G313333525 is a high-quality spherical lens from Qioptiq Photonics, a leading provider of precision optics. This lens, with a diameter of 22.4 mm, is designed for use in systems with a wavelength of 355 nm.
The lens features a double-concave geometry, with radii of curvature R1 and R2 being -50.481 mm and 50.481 mm respectively. This design results in a back focal length (BFL) of -50 mm, which is a critical parameter in lens selection. The lens has a center thickness of 1.5 mm, providing a balance between optical performance and mechanical robustness.
The lens is made from UVFS (mal- 1965), a material known for its excellent optical properties in the ultraviolet region. This material ensures high transmittance and low absorption at the operating wavelength.
The G313333525 lens comes with broadband anti-reflection coatings on both the front and back surfaces. These coatings, identified as Qio Bbar Arb2nirnbk7, are designed to minimize surface reflections and increase the overall transmission of the lens.
