LE1929-A 25.4 mm Dia. N-BK7 Positive Meniscus Lens; EFL=300mm 350-700nm

The LE1929-A is a 25.4 mm diameter Spherical Lens with a Positive Meniscus shape, sourced from the reputable optical components manufacturer, Thorlabs. This lens is specifically designed for use within the wavelength range of 350-700nm, with a central wavelength of 587.6nm, making it suitable for a wide range of optical applications.

The lens is made from N-BK7, a high-quality borosilicate glass, which is known for its excellent optical properties, including a high Abbe number and low dispersion. This makes the LE1929-A an ideal choice for applications that require high image quality and low chromatic aberration.

The lens geometry includes an effective focal length (EFL) of 300mm, a front radius (R1) of 100.9mm, and a back radius (R2) of 288.2mm. The lens has a thickness of 2mm at the edge and 2.5mm at the center. The inner and outer radii are both 0mm, indicating a uniform curvature.

The LE1929-A is coated with THo A Bbar on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, thereby enhancing the overall performance of the lens.

According to the vendor's website, the LE1929-A is currently in stock, indicating its availability for immediate purchase and use. The product's webpage also provides additional information and specifications, which may be useful for further understanding the capabilities and limitations of this lens.
