The 47-461-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 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 includes a thickness of 0.95mm at the edge and 1.75mm at the center, with an effective focal length (EFL) of 9mm. The lens's front surface has a radius of curvature of 6.05mm, and the back focal length (BFL) is 7.95mm. The lens is made from n-sf5 schott material, which is known for its high transmission and low autofluorescence.
The lens is inked, which is a process where a dye is applied to the edge of the lens to indicate its orientation. This is particularly useful in applications where the lens's orientation is critical. The lens is designed to work within the visible light spectrum, specifically between 425-675nm, making it suitable for a wide range of applications.
