HO-BVL25-3.2B 25mm Dia. N-BK7 Double-Concave Lens; EFL=-80mm BBAR 400-700nm
This is a HO-BVL25-3.2B 25mm diameter N-BK7 double-concave lens, featuring an effective focal length (EFL) of -80mm and broadband anti-reflection (BBAR) coating for the wavelength range of 400-700nm. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for its high-quality optical components.
The lens is designed with a spherical shape and a base shape of a circle. It has a diameter of 25mm and a center thickness of 2.5mm. The lens's first radius of curvature (R1) is -84.200314, while the second radius of curvature (R2) is 84.200314. The inner and outer radii are both zero.
The lens material is N-BK7, a popular choice in the optical industry due to its excellent optical properties. The BBAR coating on both the front and back surfaces further enhances the lens's performance by reducing surface reflections, thereby increasing transmission in the specified wavelength range.
The lens's EFL of -80mm indicates that it is a diverging lens, which spreads out light rays. This makes it suitable for various applications where light needs to be spread over a larger area.
The lens's coating and material data, along with its geometrical specifications, make it a versatile component for a wide range of optical systems. It is currently in stock and available for immediate use or integration into your optical setup.
