HO-PVL25-1.2C 25mm Dia. N-BK7 Plano-Concave Lens; EFL=-30mm Single Layer MgF2
The HO-PVL25-1.2C is a Plano-Concave Lens with a diameter of 25mm, sourced from Holmarc Opto-Mechatronics. This lens is designed with a single layer of MgF2 coating on both the front and back surfaces, providing excellent optical performance.
The lens is made of N-BK7, a popular glass type known for its excellent optical properties. It has a center thickness of 2.5mm and an effective focal length (EFL) of -30mm, making it suitable for a wide range of applications where a concave lens is required.
The geometry of the lens includes an inner radius of 0mm and an outer radius of 0mm, indicating a plano surface on one side and a concave surface on the other. The curvature of the concave surface is defined by a radius of -15.648mm.
This lens is designed to operate at a wavelength of 587.6nm, making it suitable for use in applications such as microscopy, beam shaping, and laser systems. The single layer MgF2 coating on both surfaces enhances the lens's performance by reducing reflection and increasing transmission.
