45-375 3.0mm Dia. x -9 FL; MgF2 Coated; Plano-Concave Lens 400-700nm
This is a 3.0mm diameter Plano-Concave lens, model 45-375, sourced from Edmund Optics. The lens is designed for use within a wavelength range of 400-700nm, making it suitable for a wide range of optical applications. The lens features a -9 FL (focal length) and a base shape of a circle.
The lens is made from n-sf11 Schott, a high-index glass with excellent transmittance in the visible spectrum. This material is known for its high Abbe number, which contributes to low chromatic aberration.
The lens's geometry includes a thickness of 1.11mm at the edge and 1mm at the center. The inner and outer radii are both 0, indicating a plano surface on both sides. The back focal length (BFL) is -9.56mm.
The lens is coated with EDM MgF2 std curve on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission, particularly within the visible spectrum. The coating status is currently in stock, according to the vendor's website.
