SLB-40B-150PIR1 40.0 mm Dia. x 150.8 mm FL; Coated; Double-Convex Lens 633-1064nm
The SLB-40B-150PIR1 is a high-quality spherical lens offered by OptoSigma, designed with a double-convex geometry and a 40.0 mm diameter. This lens boasts a long focal length of 150.8 mm, making it suitable for various applications that require precise focusing and imaging.
The lens is made from the renowned N-BK7 glass from Schott, a material known for its excellent optical properties, including low auto-fluorescence, high homogeneity, and superior transmittance across a wide spectrum (360-2500 nm). The N-BK7 glass ensures high-quality images with minimal distortions and aberrations.
The SLB-40B-150PIR1 features a front and back coating of Opt IR1, a broadband anti-reflection coating designed for the 633-1064 nm range. This coating significantly reduces surface reflections, improving light transmission and enhancing overall system performance.
The lens has a center thickness of 4.6 mm and edge thickness of 2 mm, providing robustness and durability. The inner and outer radii are 0 mm, indicating a symmetrical design that ensures consistent image quality across the entire field of view.
