HO-BVL25-04B 25mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm BBAR 400-700nm
This is the HO-BVL25-04B 25mm Dia. N-BK7 Double-Concave Lens, a high-quality optical component sourced from Holmarc Opto-Mechatronics. The lens is currently in stock and detailed information about it can be found on their official website.
The lens is of the Spherical type, specifically a Spherical Lens with a Concave-Concave base shape. It has a circular geometry with a diameter of 25mm and a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -100mm, making it a double-concave lens. The first radius of curvature (R1) is -105.003237, while the second radius of curvature (R2) is 105.003237. The inner and outer radii are both zero.
The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties. The wavelength for this lens is 587.6nm. It comes with a BBAR coating on both the front and back, specifically the hol bbbar 0 aoi coating, which is designed to reduce reflection and increase transmission in the 400-700nm range.
