112-1239E 25.4 mm Dia. x -750 mm FL; Uncoated; Plano-Concave Lens
The 112-1239E is a Plano-Concave Lens with a diameter of 25.4 mm and a focal length of -750 mm, making it a negatively powered lens. This lens is sourced from EKSMA Optics, a reputable vendor in the optical components industry. The lens's geometry includes a thickness edge of 4 mm and a thickness center of 3.8 mm, indicating a slight curvature towards the center.
The lens is made from UVFS MAL-1965, a material specifically designed for use in the ultraviolet spectrum. This makes the lens suitable for applications that involve UV light, such as UV curing, spectroscopy, or fluorescence microscopy. The lens's wavelength is 355 nm, further emphasizing its UV capabilities.
The lens is spherical in shape, a common feature in optical lenses due to its ease of manufacturing and versatility. However, it lacks any coating, which means it may not perform optimally in environments with high humidity or dust. It's essential to consider this factor when deciding where and how to use this lens.
