11-698 12.7mm Diameter x 250mm FL; Uncoated; IR Ultrafast Thin PCX Lens
The 11-698 is a 12.7mm diameter, plano-convex lens with a focal length of 250mm, making it suitable for infrared (IR) ultrafast applications. This lens, sourced from Edmund Optics, is uncoated, offering a cost-effective solution for users who do not require additional protective coatings.
The lens's geometry includes a thickness edge of 1.324mm and a thickness center of 1.5mm, with an effective focal length (EFL) of 250mm. The inner and outer radii are both zero, indicating a planar surface on one side and a curved surface on the other. The curvature of the lens is defined by a radius of 114.75mm.
The lens is made from UVFS Mal-1965, a material specifically designed for use in the ultraviolet, visible, and infrared spectra. The wavelength of 587.6nm suggests this lens is optimized for use in the visible light spectrum.
Please note that this lens does not come with any coating. Coatings can be applied to enhance the lens's performance, such as improving transmission, reducing reflection, or protecting the lens from environmental factors. However, the uncoated nature of this lens makes it a more affordable option.
