HO-PXL30-05B 30mm Dia. N-BK7 Plano-Convex Lens; EFL=150mm BBAR 400-700nm
This is a Plano-Convex lens, a type of spherical lens, sourced from Holmarc Opto-Mechatronics. The lens has a base shape of a circle and a diameter of 30mm. The thickness of the lens at the edge is 2mm, and it has an effective focal length (EFL) of 150mm. The lens is made of N-BK7, a popular glass type in the optical industry, specifically from Schott.
The lens is designed to work with a wavelength of 587.6nm. It comes with a front and back broadband anti-reflection coating (BBAR) optimized for 400-700nm, indicated as "hol bbbar 0 aoi" in the item data. This coating helps to reduce reflection and increase transmission, enhancing the performance of the lens.
The item data also provides the radius of curvature for the first surface (r1) as 78.242mm. The inner and outer radii are both 0mm, indicating that the lens is a Plano-Convex lens, where one surface is flat (Plano) and the other is curved (Convex).
