HO-BVL25-3.2C 25mm Dia. N-BK7 Double-Concave Lens; EFL=-80mm Single Layer MgF2
This HO-BVL25-3.2C optical lens, sourced from Holmarc Opto-Mechatronics, is a double-concave spherical lens with a base shape of a circle. The lens has a diameter of 25mm and a center thickness of 2.5mm. The effective focal length (EFL) of this lens is -80mm, making it a negative or diverging lens.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. The inner and outer radii of the lens are 0, indicating a symmetrical design.
The lens is coated with a single layer of MgF2 on both the front and back surfaces. This coating, denoted as "hol mgf2 0 aoi," is designed to reduce reflection and improve transmission, making the lens more efficient in transmitting light.
The lens is designed for use at a wavelength of 587.6nm. This wavelength falls within the visible light spectrum, suggesting that this lens is intended for use in applications involving visible light.
