16-274 30mm Dia. S-LAH64 NIR Aspheric Lens; EFL=26mm; NA=0.58 VIS Plus 350-700nm

The 16-274 is a high-quality aspheric lens offered by Edmund Optics, designed for use in the near-infrared (NIR) spectrum. This lens boasts a 30mm diameter and a numerical aperture (NA) of 0.58, making it a versatile choice for a variety of optical applications.

The lens is made from S-LAH64, a material from Ohara that is known for its excellent optical properties. The S-LAH64 material ensures high transmittance in the NIR spectrum, specifically between 350nm and 700nm, making it ideal for use in systems operating in this range.

The lens features an effective focal length (EFL) of 26mm, which is a good balance between magnification and field of view. The aspheric design of the lens helps to reduce spherical aberration, improving the overall image quality. The lens has a center thickness of 9.65mm and an edge thickness of 3.82mm, providing robustness and durability.

The 16-274 lens comes with a VIS Plus coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the NIR spectrum, reducing reflections and increasing transmission. The coating also provides protection against environmental factors, ensuring the longevity of the lens.
