The SLB-50-220NIR1 is a Plano-Concave Spherical Lens, 50.0 mm in diameter, with a focal length of -220.0 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 applications.
The lens has a thickness of 5.8 mm at the edge and 3 mm at the center, providing a balanced structure for efficient light transmission. The Inner and Outer Radius are both 0, indicating a uniform curvature. The Back Focal Length (BFL) is -222 mm, slightly longer than the Effective Focal Length (EFL) of -220 mm, which is typical for Plano-Concave lenses.
The lens 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.
