HO-BVL25-06C 25mm Dia. N-BK7 Double-Concave Lens; EFL=-150mm Single Layer MgF2
This is the HO-BVL25-06C 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) is -150mm, indicating that it is a diverging lens. The first radius of curvature (R1) is -157.081793, while the second radius of curvature (R2) is 157.081793, both measured in millimeters. The lens does not have an inner or outer radius.
The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties. The material is identified as "n-bk7 schott" in the item data.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating, denoted as "hol mgf2 0 aoi", is designed to reduce reflection and improve transmission, making the lens more efficient in transmitting light.
The lens is designed for use with a wavelength of 587.6nm. It is a spherical lens, a common type of lens used in many optical systems.
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.
