HO-BVL25-04C 25mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm Single Layer MgF2
This is the HO-BVL25-04C 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 -100mm, which is a crucial specification for determining the lens's focusing power. The inner and outer radii of the lens are 0, indicating a symmetrical design.
The lens is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties. It is coated with a single layer of MgF2 on both the front and back surfaces, which is denoted as 'hol mgf2 0 aoi'. This coating enhances the lens's performance by reducing surface reflections and improving transmission.
The lens is designed for use at a wavelength of 587.6nm. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status. For more information about this product, please refer to the vendor's website at https://www.holmarc.com/bi_concave_lenses.php.
