87-916-INK 5.0mm Dia. x 30.0mm FL; VIS 0deg; Inked; Plano-Convex Lens VIS 0° 425-675nm
The 87-916-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 5.0mm, is designed for use within the visible light spectrum, specifically at a wavelength of 587.6nm. The lens has a front and back coating of edm vis-0 std curve, providing standard anti-reflection properties.
The lens's geometry is characterized by a thickness of 1.4mm at the edge and 1.6mm at the center, with an effective focal length (EFL) of 30.0mm. The radius of curvature for the first surface (R1) is 15.5mm, and the back focal length (BFL) is 28.95mm. The lens does not have an inner or outer radius, indicating a uniform curvature across the lens surface.
The lens is made from n-bk7 schott, a common optical material known for its high refractive index and low dispersion. This makes it suitable for a wide range of optical applications. The lens is inked, a process that adds a dye or paint to the lens to enhance its visibility or mark it for identification purposes.
The lens's coating and material properties make it suitable for use within the visible light spectrum, specifically between 425nm and 675nm. This makes it a versatile option for various applications that require a small, high-performance lens.
