HO-BVL25-3.2 25mm Dia. N-BK7 Double-Concave Lens; EFL=-80mm Uncoated
This is a HO-BVL25-3.2 25mm Dia. N-BK7 Double-Concave Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens is designed with a base shape of a circle and features a double-concave geometry, making it suitable for a wide range of optical applications.
The lens has a diameter of 25mm and a center thickness of 2.5mm. It boasts an effective focal length (EFL) of -80mm, indicating its concave nature. The first radius of curvature (R1) is -84.200314, while the second radius of curvature (R2) is 84.200314, further emphasizing its double-concave design. The lens does not have an inner or outer radius, suggesting a uniform curvature throughout.
The lens is made from N-BK7 Schott, a popular material in the optical industry due to its excellent optical properties. It is designed to work with a wavelength of 587.6nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties. However, it can be customized with various coatings upon request.
The lens is currently in stock and available for purchase. For more information, please refer to the vendor's website at https://www.holmarc.com/bi_concave_lenses.php.
