HO-BVL50-02B 50mm Dia. N-BK7 Double-Concave Lens; EFL=-100mm BBAR 400-700nm
This is a HO-BVL50-02B 50mm diameter N-BK7 double-concave lens, featuring an effective focal length (EFL) of -100mm. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor in the optical industry.
The lens is designed with a base shape of a circle and is constructed with N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The geometry of the lens includes a diameter of 50mm, a center thickness of 2.5mm, and radii of curvature of -105.759416mm for the first surface and 105.759416mm for the second surface.
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, thereby improving the overall efficiency of the optical system. The BBAR coating is applied to both the front and back surfaces of the lens.
The HO-BVL50-02B lens is available for purchase from the Holmarc Opto-Mechatronics website, and as per the latest information, it is in stock. The link to the product page is provided for your convenience.
