This is a mounted plano-convex lens, type G063827329, manufactured by Qioptiq Photonics. The lens boasts a diameter of 25.4 mm and an effective focal length (EFL) of 500mm at a wavelength of 1064nm. The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties and versatility.
The lens's geometry is characterized by a plano-convex shape, meaning one side is flat (plano) and the other side is curved (convex). The radius of curvature for the curved side is 260.39 mm. The lens has a thickness of 3.7 mm at the edge and 4 mm at the center.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating enhances the lens's performance by reducing reflection and increasing transmission, particularly at the specified wavelength of 1064nm.
