HO-PVL25-40C 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-1000mm Single Layer MgF2
This HO-PVL25-40C optical lens, sourced from Holmarc Opto-Mechatronics, is a 25mm diameter Plano-Concave Spherical Lens with a single layer MgF2 coating. The lens is designed for use at a wavelength of 587.6nm, making it suitable for a wide range of optical applications.
The lens features a concave shape with a center thickness of 2.5mm and an effective focal length (EFL) of -1000mm. The inner and outer radii are both zero, indicating a plano surface on one side and a concave surface on the other. The lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating is designed to reduce reflection and improve transmission, enhancing the overall performance of the lens. The coating is applied using a Holmarc-specific process, ensuring high quality and durability.
