49-239 6mm Dia. x 9mm FL; Uncoated; UV Double-Convex Lens

The 49-239 is a high-quality spherical lens, boasting a base shape of a perfect circle, sourced from the reputable vendor, Edmund Optics. This lens is specifically designed for use in ultraviolet (UV) applications, making it an ideal choice for projects requiring precise UV light manipulation.

The lens has a diameter of 6mm, ensuring a wide field of view while maintaining a compact form factor. The effective focal length (EFL) is 9mm, indicating a moderate level of magnification. This makes the lens suitable for a range of applications, from imaging to laser beam shaping.

The lens features a double-convex geometry, with radii of curvature of 7.8mm for the first surface and -7.8mm for the second. This design allows for excellent light gathering and focusing capabilities. The lens has a thickness of 1.5mm at the edge and 2.7mm at the center, providing structural rigidity while minimizing optical aberrations.

The lens is made from fused silica, a material with a high transmission rate in the UV spectrum. This ensures optimal performance in UV applications. The lens is uncoated, which may be beneficial in certain applications where a specific coating is not required or desirable.
