HO-PVL25-3.2 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-80mm Uncoated

This HO-PVL25-3.2 optical lens is a 25mm diameter Plano-Concave lens, sourced from the reputable vendor Holmarc Opto-Mechatronics. The lens is made of N-BK7, a popular material in the optical industry, known for its excellent optical properties. The lens is uncoated, which means it does not have any additional layers to enhance its optical performance or protect it from environmental factors.

The lens has a negative focal length (EFL) of -80mm, indicating that it is a diverging lens. This type of lens is often used in applications where light needs to be spread out, such as in projectors or beam expanders. The lens's geometry includes a center thickness of 2.5mm and a radius of curvature (R1) of -41.729mm. The lens's inner and outer radii are both zero, indicating that the lens is flat on both sides except for the curved center.

This lens is designed to work with light of a specific wavelength, 587.6nm, which is in the yellow-green part of the visible light spectrum. This makes it suitable for applications that use this specific wavelength, such as certain types of lasers or specialized lighting systems.
