G313330322 22.4 mm Dia. UVFS Double-Concave Lens; EFL=-20mm
The G313330322 is a spherical lens with a base shape of a circle, featuring a double-concave design. This lens is sourced from Qioptiq Photonics, a renowned vendor in the field of precision optics. The lens has a diameter of 22.4 mm and a center thickness of 1.5 mm, making it a compact yet robust optical component.
The effective focal length (EFL) of this lens is -20mm, indicating its concave nature. The first radius of curvature (R1) is -20.535mm, and the second radius of curvature (R2) is 20.535mm, further emphasizing its double-concave structure. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.
This lens is made of UVFS material with the ID MAL-1965. It is designed to operate at a wavelength of 355nm, making it suitable for applications in the ultraviolet spectrum. The lens is coated on both the front and back with Qio Bbar Arb2visnbk7, a broadband anti-reflection coating that enhances its transmission capabilities.
