LA1074-780 N-BK7 Plano-Convex Lens; Dia:0.5 in; f=20.0 mm 780nm V-Coat
The LA1074-780 is a Plano-Convex lens, a type of spherical lens, sourced from Thorlabs, a renowned optical components manufacturer. This lens is designed for use in the visible spectrum, specifically at a wavelength of 587.6 nm. The lens is made from N-BK7, a popular glass type known for its excellent optical properties, including high homogeneity and low auto-fluorescence.
The lens has a diameter of 12.7 mm and a thickness at the edge of 1.8 mm. The center thickness is 4 mm, providing a robust structure for various applications. The effective focal length (EFL) of this lens is 20 mm, making it suitable for use in systems requiring moderate magnification or field of view.
The LA1074-780 features a front and back coating of tho 780 n-bk7 vc 780, which is a broadband anti-reflection coating designed for use at 780 nm. This coating reduces surface reflections, enhancing the overall transmission of the lens and minimizing unwanted optical losses.
