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 has a diameter of 25mm and a thickness at the edge of 2mm. The effective focal length (EFL) of this lens is 80mm, making it suitable for applications that require a longer focal length.
The lens is made of N-BK7, a type of glass commonly used in optical applications due to its excellent optical properties. This specific lens is sourced from Holmarc Opto-Mechatronics, a reputable vendor known for their high-quality optical components.
The lens features BBAR coating on both the front and back surfaces. BBAR, or Broadband Anti-Reflection coating, is designed to reduce reflection and increase transmission of light across a broad spectrum, in this case, 400-700nm. This makes the lens ideal for applications that require high transmission and low reflection, such as imaging systems, beam shaping, and laser applications.
