SLB-50-90NIR1 50.0 mm Dia. x -90.0 mm FL; Coated; Plano-Concave Lens 633-1064nm
The SLB-50-90NIR1 is a Plano-Concave Spherical Lens, 50.0 mm in diameter, with a focal length of -90.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of n-bk7 schott, a high-quality optical glass, and features a Plano-Concave geometry, making it suitable for a wide range of optical applications.
The lens has a center thickness of 3 mm and an edge thickness of 10.3 mm, providing excellent structural integrity. The inner and outer radii are both 0 mm, indicating a uniform curvature. The lens's effective focal length (EFL) is -90 mm, and the back focal length (BFL) is -92 mm, which are crucial specifications for designing and integrating this lens into optical systems.
The SLB-50-90NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating ensures high transmission and low reflection, making the lens ideal for use in laser applications and other settings where precise light control is required.
