SLSQ-05B-30P 5.0 mm Dia. x 30.2 mm FL; Double-Convex Lens Uncoated

The SLSQ-05B-30P is a high-quality, double-convex lens offered by OptoSigma, a renowned vendor in the optical industry. This lens, with a diameter of 5.0 mm, is designed for use in various optical applications, thanks to its precise geometry and material composition.

The lens features a double-convex shape, meaning it has two spherical surfaces that curve outwards. This design is characterized by its radii of curvature, R1 and R2, which are equal at 27.6 mm, indicating a symmetrical lens. The lens's thickness varies from 1.1 mm at the edge to 1.3 mm at the center, providing a balanced structure for efficient light transmission.

The effective focal length (EFL) of this lens is 30.2 mm, which is the distance from the lens's center to the point where parallel light rays converge after passing through the lens. This EFL, combined with the lens's diameter, makes it suitable for applications requiring a compact, high-performance lens.

The lens is made of fused silica, a material known for its excellent optical properties, including high transparency and resistance to thermal shock. The material ID, fused sil mal-1965, indicates a specific type of fused silica used in this lens.

The wavelength of 546.1 nm suggests that this lens is designed for use in the visible light spectrum. However, it's important to note that the lens does not come with any coating, which means it may not perform optimally in environments with high light intensity or where specific light manipulation is required.
