542-7105 12.7 mm Dia. x -25 mm FL; Uncoated; Plano-Concave Lens
The 542-7105 is a Plano-Concave Spherical Lens, sourced from EKSMA Optics, a renowned vendor in the optical components industry. This lens boasts a circular base shape with a diameter of 12.7 mm and a center thickness of 2.5 mm. The lens is designed with a -25 mm focal length (FL), making it suitable for applications that require a negative lens.
The lens is crafted from Barium Fluoride (BaF2), a material with a refractive index of 1.45 at 3000 nm. This material is often chosen for its excellent transparency in the ultraviolet (UV) and infrared (IR) regions of the spectrum. The lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
