LA5042-D 25.4 mm Dia. CaF2 Plano-Convex Lens; EFL=75mm 1.65-3µm
The LA5042-D is a Plano-Convex lens with a diameter of 25.4 mm, designed for use in the infrared spectrum with a wavelength of 588 nm. This lens is sourced from Thorlabs, a reputable vendor known for its high-quality optical components.
The lens is made from Calcium Fluoride (CaF2), a material with a high transmission range in the infrared spectrum, making it ideal for applications in this range. The lens has an effective focal length (EFL) of 75 mm, providing a moderate level of magnification.
The LA5042-D features a Plano-Convex geometry, with a flat front surface and a curved back surface. The thickness at the edge of the lens is 2 mm, while the center thickness is 4.6 mm. The lens does not have any inner or outer radii, indicating a simple, straightforward design.
The lens is coated with a broadband anti-reflection coating, denoted as "tho d bbar" for both the front and back surfaces. This coating reduces surface reflections, improving the overall transmission of the lens.
