HO-BVL25-1.2B 25mm Dia. N-BK7 Double-Concave Lens; EFL=-30mm BBAR 400-700nm
This is a HO-BVL25-1.2B Double-Concave Lens from Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. The lens, with a base shape of a circle, is designed for use in various optical systems that require a concave-concave lens geometry.
The lens has a diameter of 25mm and a center thickness of 2.5mm, making it compact and suitable for applications where space is a constraint. The effective focal length (EFL) of this lens is -30mm, indicating its double-concave nature.
The lens is made of N-BK7, a popular optical glass from Schott, known for its excellent optical properties and wide transparency range. The curvature of the lens is defined by two radii, R1 and R2, which are -32.532744mm and 32.532744mm respectively.
The lens is coated with BBAR (Broadband Anti-Reflection) coating, optimized for the wavelength of 587.6nm. This coating enhances the lens's performance by reducing reflection and increasing transmission, making it suitable for use in a wide range of wavelengths from 400nm to 700nm.
The lens is currently in stock and available for immediate purchase. For more information, you can visit the vendor's website through the provided weblink.
