A375-A 6.51 mm Dia. H-LAK54 Molded Glass Aspheric Lenses; EFL=7.5 mm; NA=0.3 AR 350-700nm
The A375-A is a high-quality aspheric lens from Thorlabs, designed with a 6.51 mm diameter and a molded H-LAK54 glass material. This lens is specifically engineered for use in the 810 nm wavelength range, offering exceptional performance and precision.
The lens features an effective focal length (EFL) of 7.5 mm, providing a compact and efficient optical solution. The aspheric design of the lens helps to reduce spherical aberration, enhancing the quality of the image formed. The lens has a front thickness of 1.71 mm and a center thickness of 2.75 mm, contributing to its robust construction and durability.
The A375-A is coated with a broadband anti-reflective coating (AR 350-700nm) on both the front and back surfaces. This coating significantly reduces unwanted reflections, improving light transmission and enhancing the overall system performance. The lens also has a numerical aperture (NA) of 0.3, which determines the light-gathering ability of the lens and its ability to resolve fine details.
This lens is available for purchase directly from Thorlabs, with the weblink provided in the item data indicating its current availability. The catalog number A375-A can be used for easy reference and ordering.
