SLSQ-25-35N 25.0 mm Dia. x -35.0 mm FL; Plano-Concave Lens Uncoated
The SLSQ-25-35N is a Plano-Concave Spherical Lens, uncoated, with a diameter of 25.0 mm and a focal length of -35.0 mm. This lens is sourced from OptoSigma, a renowned vendor in the optical industry. The lens is made of fused silica, a material known for its excellent optical properties, durability, and resistance to thermal shock.
The lens geometry includes a thickness edge of 8.0 mm and a thickness center of 2.0 mm, providing a balanced structure for various applications. The inner and outer radii are both 0.0 mm, indicating a uniform curvature. The effective focal length (EFL) is -35.0 mm, and the back focal length (BFL) is -36.4 mm, suggesting a strong focusing power.
The lens is designed for a wavelength of 546.1 nm, making it suitable for applications that require high precision and accuracy in the visible light spectrum. The uncoated surface allows for versatility in applications, although it may have higher reflectivity compared to coated lenses.
