16-297 25mm Dia. N-BK7 NIR Aspheric Lens; EFL=50mm; NA=0.25 SWIR-Plus 900-1700nm

The 16-297 is a high-quality aspheric lens, designed and manufactured by Edmund Optics, a leading global supplier of optical components. This lens boasts a 25mm diameter and a numerical aperture (NA) of 0.25, making it suitable for a wide range of applications.

The lens is made from N-BK7, a popular optical glass due to its excellent optical properties and high transmittance in the near-infrared (NIR) region. The N-BK7 material ensures high-quality imaging and minimal distortion, making it ideal for use in systems where image fidelity is paramount.

The aspheric design of the lens provides superior performance over traditional spherical lenses. It corrects for spherical aberration, a common issue in optical systems, which results in clearer, sharper images. The lens has a focal length of 50mm (EFL), providing a good balance between field of view and image magnification.

The lens is coated with Edmund Optics' SWIR-Plus coating, designed for the 900-1700nm spectral range. This coating enhances the lens's transmission in the NIR region, reducing reflection and increasing the amount of light passing through the lens. The coating also provides excellent environmental resistance, ensuring the lens maintains its performance even in challenging conditions.

The 16-297 lens is currently in stock and available for immediate shipping. With its high-quality materials, advanced design, and superior performance, this lens is an excellent choice for any application requiring a high-performance NIR lens.
