SPX012AR.10 12.7 mm Dia. x 19.0 mm FL; AR coated; Plano-Convex Lens AR 245-440nm

The SPX012AR.10 is a Plano-Convex Spherical Lens, sourced from the reputable vendor MKS/Newport. This lens boasts a diameter of 12.7 mm and a focal length of 19.0 mm, making it a compact yet powerful optical component. The lens is fabricated from UVFS MA-L 1965, a material specifically designed for use in the ultraviolet spectrum, with a central thickness of 5.75 mm and an edge thickness of 3 mm, providing a robust structure.

The lens features an Anti-Reflective (AR) coating on both the front and back surfaces, designated as 'new ar-10 fromfigure'. This coating is designed to operate within the wavelength range of 245-440 nm, effectively reducing surface reflections and increasing transmission in the ultraviolet range. The lens's base shape is circular, and its inner radius is zero, indicating a plano surface on the opposite side of the convex surface.

The lens's geometry includes an effective focal length (EFL) of 19.0 mm, a back focal length (BFL) of 15.06 mm, and a radius of curvature (R1) of 8.71 mm. These parameters are crucial in determining the lens's performance in optical systems. The lens's EFL and BFL are essential for accurate placement within an optical system, while R1 influences the curvature and focusing power of the lens.
