The 38-439-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 6.0mm, is designed for use within the visible light spectrum, specifically between 350-700nm. The lens features a front and back coating of edm vis ext, which is a proprietary coating developed by Edmund Optics to enhance the lens's performance within the visible light spectrum.
The lens has a thickness of 1.1mm at the edge and 1.45mm at the center, with an effective focal length (EFL) of 25mm. The radius of curvature for the first surface (R1) is 12.92mm, and the back focal length (BFL) is 24.04mm. The lens does not have an inner radius, and the outer radius is also 0, indicating a uniform curvature.
The 38-439-INK lens is made of n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This makes it an ideal choice for applications that require high light transmission and low background noise.
