HO-BVL25-04 25mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm Uncoated
This is a HO-BVL25-04 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. The effective focal length (EFL) of this lens is -100mm, indicating that it is a diverging lens. The first radius of curvature (R1) is -105.003237mm, and the second radius of curvature (R2) is 105.003237mm, demonstrating the double-concave nature of the lens. The inner and outer radii are both 0mm, indicating a uniform curvature throughout the lens.
The lens is made of N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties. The wavelength for this lens is 587.6nm. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties.
This lens is available from Holmarc Opto-Mechatronics and is currently in stock. For more information, please refer to the vendor's website.
