LE1929-C 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=300mm 1050-1700nm
The LE1929-C is a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use within the wavelength range of 1050-1700nm, making it suitable for a variety of applications within the near-infrared spectrum.
The lens features an effective focal length (EFL) of 300mm, which is a critical parameter in determining the lens's magnification capabilities. The EFL, combined with the lens's geometry, allows for precise focusing and imaging. The lens's geometry includes a 2mm edge thickness and a 2.5mm center thickness, contributing to its robustness and durability.
The LE1929-C is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material ensures high transmission and low dispersion, making it ideal for applications that require high-resolution imaging or precise light control.
The lens is coated with a Thorlabs C Broadband Anti-Reflection coating on both the front and back surfaces. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
