HO-PXL30-2.5B 30mm Dia. N-BK7 Plano-Convex Lens; EFL=75mm BBAR 400-700nm
This is a Plano-Convex lens, a type of spherical lens with a flat surface on one side and a curved surface on the other. The lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for its high-quality optical elements. The lens has a diameter of 30mm and a thickness of 2.5mm at the edge, making it suitable for a wide range of optical applications.
The lens features an effective focal length (EFL) of 75mm, which is the distance from the center of the lens to the point at which light rays converge or diverge. This makes it a medium to long-focus lens, ideal for applications that require moderate magnification.
The lens is made from N-BK7, a type of high-quality borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low dispersion and high transmission in the visible spectrum.
The lens is coated with BBAR (Broadband Anti-Reflection) coating, which reduces reflection and increases transmission across a broad spectrum of light, specifically from 400 to 700nm. This coating enhances the lens's performance in a wide range of lighting conditions and applications.
