LB4330-B UV Fused Silica Bi-Convex Lens; Dia:1 in; f=75.0 mm ARC 650-1050nm
The LB4330-B is a high-quality UV Fused Silica Bi-Convex Lens, sourced from the reputable vendor Thorlabs. This lens boasts a diameter of 1 inch (25.4 mm) and a focal length of 75.0 mm, making it suitable for a wide range of optical applications.
The lens is designed with a Spherical shape, featuring a front and back curvature of 68.3 mm and -68.3 mm respectively. This bi-convex design allows for superior light transmission and focus, enhancing the overall performance of your optical system. The lens has an effective focal length (EFL) of 75 mm and a back focal length (BFL) of 73.5 mm.
The LB4330-B is crafted from high-quality UV Fused Silica, a material known for its excellent transmission properties across a broad spectrum, particularly in the ultraviolet range. This makes the lens ideal for applications that require high-transmission in the UV spectrum.
The lens is coated with a THo BBAR coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections, thereby increasing the amount of light transmitted through the lens. The coating is optimized for the 650-1050 nm range, making it suitable for a wide range of applications.
