LA1304-YAG N-BK7 Plano-Convex Lens; Dia:0.5 in; f=40.0 mm YAG V-Coat 532/1064nm
This is a LA1304-YAG N-BK7 Plano-Convex Lens, a high-quality optical component sourced from Thorlabs. The lens, which is 0.5 inches in diameter, is designed with a plano-convex geometry, featuring a flat front surface and a curved back surface. This particular model has a focal length of 40.0 mm, making it suitable for a wide range of optical applications.
The lens is made from N-BK7, a type of borosilicate glass known for its excellent optical properties. This material is often used in high-precision optical systems due to its low coefficient of thermal expansion and high homogeneity. The lens has a central thickness of 2.8 mm and an edge thickness of 1.8 mm, providing robustness and durability.
The LA1304-YAG lens features a YAG V-Coat coating on both the front and back surfaces. This coating is specifically designed for use at 532 nm and 1064 nm wavelengths, enhancing the lens's performance in these regions. The coating provides high transmission and low reflectivity, making it ideal for applications such as laser systems and interferometry.
