The KPX178AR.33 is a Plano-Convex Spherical Lens, sourced from MKS/Newport, with a diameter of 50.8 mm and a focal length of 62.9 mm. This lens is designed for use with a wavelength of 589 nm and is made from N-BK7 Schott material, a popular choice for its high refractive index and low dispersion.
The lens features a New AR-33 coating on both the front and back surfaces, which is specifically designed to minimize reflection at 1064 nm. This coating ensures high transmission and low loss, making it ideal for applications such as laser systems and interferometry.
The lens has a thickness of 3 mm at the edge and 15.221 mm at the center. The inner radius is 0, and the back focal length is 52.86 mm. The base shape is circular, and the geometry is designed for optimal performance in a wide range of optical systems.
