Holmarc Opto-Mechatronics offers the HO-BXL50-06, a 50mm diameter N-BK7 double-convex lens with an effective focal length (EFL) of 300mm. This uncoated lens is designed for applications that do not require anti-reflective coatings.
The lens features a base shape of a circle and is constructed with N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion. The geometrical specifications include a diameter of 50mm, a thickness edge of 3mm, and radii of curvature (R1 and R2) of 312.109243mm and -312.109243mm, respectively. The lens's inner and outer radii are both zero.
The wavelength for this lens is 587.6nm, and it is spherical in shape. The provided item data does not include any information about coatings, so it is assumed that this lens is uncoated.
