The SLB-30-80NIR1 is a Plano-Concave Spherical Lens, 30.0 mm in diameter and featuring a focal length of -80.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made from n-bk7 schott material, a high-quality borosilicate glass known for its excellent optical properties.
The lens's geometry includes a thickness edge of 4.8 mm and a thickness center of 2 mm, providing a balanced structure for various applications. The lens's effective focal length (EFL) is -80 mm, and its front and back radii are -41.52 mm and -81.3 mm, respectively. The lens's inner and outer radii are both 0 mm, indicating a uniform curvature.
The SLB-30-80NIR1 is coated with opt ir1 on both the front and back surfaces, enhancing its performance in the 633-1064nm wavelength range. This coating ensures optimal transmission and reduces reflection, making it suitable for use in laser applications and other scenarios where high-transmission is required.
