This is a mounted plano-convex lens, type G052117329, manufactured by Qioptiq Photonics. The lens has a diameter of 12.7 mm and a thickness of 2.9 mm at the edge, while the center thickness is 3 mm. The effective focal length (EFL) of this lens is 300 mm, specifically designed for use with a wavelength of 588 nm.
The lens is made of N-BK7, a popular optical glass from Schott, which is known for its excellent optical properties. The lens features a spherical shape, with a radius of curvature (R1) of 153.99 mm for the curved surface. The inner and outer radii are both zero, indicating a plano surface on the other side.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to enhance the lens' performance in the infrared region, particularly at 1064 nm, making it suitable for various applications in this spectrum.
The lens is mounted, making it ready for immediate use in your optical system. According to the vendor's website, this item is currently in stock, ensuring quick delivery upon order.
