LE1234-B 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=100mm 650-1050nm
This is the LE1234-B lens, a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the reputable optical components manufacturer, Thorlabs. The lens is made of N-BK7, a popular glass type known for its excellent optical properties, particularly its low dispersion and high Abbe number.
The lens features a focal length (EFL) of 100mm, making it suitable for a wide range of applications that require moderate magnification. The wavelength of 587.6nm suggests that this lens is designed to operate effectively within the visible light spectrum.
The lens's geometry includes a thickness of 2mm at the edge and 3.6mm at the center, providing a robust structure while maintaining a relatively thin profile. The inner and outer radii are 0, indicating a symmetrical design. The front and back surfaces of the lens are coated with tho b bbar, a broadband anti-reflection coating that enhances transmission and reduces surface reflections.
The LE1234-B lens is currently in stock and available for immediate purchase through the Thorlabs website. Its Spherical shape, Positive Meniscus design, and N-BK7 material make it a versatile and reliable choice for various optical applications.
