49-902-INK 20.0mm Dia. x 35.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 49-902-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 20.0mm, is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of edm vis-0 std curve, providing standard performance and durability.
The lens has a thickness of 1.48mm at the edge and 4.5mm at the center, with an effective focal length (EFL) of 35mm. The radius of curvature for the first surface (R1) is 18.09mm, and the back focal length (BFL) is 32.04mm. The lens does not have an inner or outer radius, indicating a uniform curvature.
The lens is made from n-bk7 schott, a high-quality optical glass known for its excellent transmittance and low auto-fluorescence. This material makes the lens suitable for various applications within the visible light spectrum, ranging from 425 to 675nm.
The lens's geometry and material make it a versatile option for various optical systems. Its plano-convex design allows for efficient light transmission while minimizing spherical aberration. The edm vis-0 std curve coating ensures durability and maintains the lens's performance over time.
