SLSQ-40-150N 40.0 mm Dia. x -150.0 mm FL; Plano-Concave Lens Uncoated

The SLSQ-40-150N is a Plano-Concave Lens with a diameter of 40.0 mm and a focal length of -150.0 mm, sourced from OptoSigma. This 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 5.0 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 flat surface on one side and a concave surface on the other. The lens's effective focal length (EFL) is -150.0 mm, and the radius of curvature (R1) is -69.0 mm. The back focal length (BFL) is -151.4 mm.

This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties. However, uncoated lenses can be advantageous in certain applications where specific coatings might interfere with the desired optical effects.

The lens is designed for a wavelength of 546.1 nm, making it suitable for applications that use this wavelength, such as certain types of fluorescence microscopy.
