HO-PVL25-02C 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-50mm Single Layer MgF2
This HO-PVL25-02C optical lens, sourced from Holmarc Opto-Mechatronics, is a 25mm diameter Plano-Concave Spherical Lens with a center thickness of 2.5mm. The lens has a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence.
The lens is made of N-BK7, a popular optical glass known for its excellent optical properties, including high transparency and low auto-fluorescence. This material is widely used in various optical systems due to its superior performance and versatility.
The lens features a single layer of MgF2 coating on both the front and back surfaces. This coating is designed to enhance the lens's performance by reducing surface reflections and improving transmission. The coating is applied at 0 degrees angle of incidence (AOI), ensuring uniform coverage and optimal performance.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a simple Plano-Concave design. The wavelength for this lens is 587.6nm, which is within the visible light spectrum.
