13-503 25mm Dia. N-BK7 NIR Aspheric Lens; EFL=50mm; NA=0.25 Uncoated

This is a high-quality 13-503 25mm Dia. N-BK7 NIR Aspheric Lens, designed for use in the near-infrared spectrum with a wavelength of 780nm. The lens is sourced from the renowned optical vendor, Edmund Optics, and is available for purchase through their website. The current status indicates that the lens is in stock, ensuring quick delivery for your optical project needs.

The lens is a precision-engineered aspheric design, featuring a base shape of a circle and a material ID of N-BK7 Schott. This specific type of glass is known for its excellent optical properties, making it a popular choice for various applications. The lens has a diameter of 25mm and a thickness of 2.86mm at the edge, with a center thickness of 6mm.

The effective focal length (EFL) of this lens is 50mm, and it has a numerical aperture (NA) of 0.25. The asphere has an inner radius of 0mm and an outer radius of 0mm, with a back focal length (BFL) of 46.03mm. The lens's shape is defined by its aspheric surface with a conic constant of -0.7, ensuring high-quality imaging and minimal aberrations.

The coating of this lens is uncoated, which means it does not have any additional anti-reflective or protective coatings. This may be suitable for certain applications; however, users should consider the potential implications of using an uncoated lens, such as increased reflection and potential susceptibility to environmental factors.
