48-039 12mm Dia. x 75mm FL; Uncoated; UV Double-Convex Lens

The 48-039 is a 12mm diameter, double-convex lens with a focal length of 75mm, sourced from Edmund Optics. This lens is uncoated and optimized for use in the ultraviolet (UV) spectrum, making it an ideal choice for applications that require high transmittance in this range.

The lens geometry features a center thickness of 2.59mm and an edge thickness of 2.06mm, providing a robust structure while maintaining a compact form factor. The base shape is circular, ensuring consistent performance across all axes. The lens has an effective focal length (EFL) of 75mm, which, combined with its double-convex shape, provides a wide field of view and low distortion.

The lens is made from fused silica (mal-1965), a material known for its excellent optical properties, including high transparency, low autofluorescence, and high resistance to thermal shock and chemical etching. This makes the 48-039 suitable for use in harsh environments and applications that require high precision and durability.

The lens is designed to operate at a wavelength of 587.6nm, although its UV optimization makes it suitable for use across a broader UV spectrum. The lens shape is spherical, ensuring consistent performance and easy integration into optical systems. The coating is absent, which can be beneficial in applications where anti-reflection coatings may interfere with the desired optical performance.
