HO-BVL25-12 25mm Dia. N-BK7 Double-Concave Lens; EFL=-300mm Uncoated
The HO-BVL25-12 is a high-quality double-concave lens offered by Holmarc Opto-Mechatronics, a renowned vendor in the optical industry. This lens is specifically designed for applications that require a concave-concave spherical lens with a circular base shape.
The lens has a diameter of 25mm and a center thickness of 2.5mm, making it compact and suitable for various optical setups. The effective focal length (EFL) of this lens is -300mm, indicating its diverging nature. This property is further emphasized by its first and second radius of curvature, R1 and R2, which are -313.48273mm and 313.48273mm respectively.
The lens is made of N-BK7, a popular glass type in the optical industry due to its excellent optical properties. This material is sourced from Schott, a leading glass manufacturer, ensuring high quality and reliability.
The lens is designed to operate at a wavelength of 587.6nm, making it suitable for applications that use this specific wavelength. However, it's important to note that the lens does not come with any coating, which may affect its performance in certain applications.
