The 34-186-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 40.0mm, is designed for use in the visible light spectrum, specifically at a wavelength of 587.6nm. The lens features a front and back coating of YAG-BBAR, a type of anti-reflection coating that enhances transmission in the 500-1100nm range.
The lens has a thickness of 2.84mm at the edge and 8.0mm at the center, with a focal length (EFL) of 80.0mm. The radius of curvature for the first surface (R1) is 41.34mm, and the back focal length (BFL) is 74.73mm. The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high Abbe number.
The YAG-BBAR coating on this lens reduces surface reflections, increasing the amount of light transmitted through the lens. This makes it ideal for applications where high transmission and low loss are critical, such as in imaging systems, beam delivery systems, and optical instruments.
Please note that the lens is inked, which is a common practice in the optical industry to mark lenses for identification and tracking purposes. This does not affect the lens's optical performance.
