HO-PVL25-04B 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-100mm BBAR 400-700nm
This is a Plano-Concave Spherical Lens, type HO-PVL25-04B, manufactured by Holmarc Opto-Mechatronics. The lens has a base shape of a circle and a diameter of 25mm. The center thickness of the lens is 2.5mm, and it has an effective focal length (EFL) of -100mm. The lens is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion.
The lens's front and back surfaces are coated with BBAR (Broadband Anti-Reflection) coating, optimized for a wavelength of 587.6nm and an angle of incidence of 0 degrees. This coating reduces reflection and increases transmission, making it ideal for use in a wide range of applications, including imaging systems, beam shaping, and laser applications.
The BBAR coating on this lens is designed to operate within the wavelength range of 400-700nm. This makes it suitable for use in systems that operate within the visible light spectrum. The lens's concave shape allows it to diverge light, making it ideal for use in applications where beam expansion is required.
The HO-PVL25-04B lens is currently in stock and available for purchase on the Holmarc Opto-Mechatronics website. The website also provides additional information about the lens, including its specifications and applications.
