13-505 45mm Dia. S-LAH64 NIR Aspheric Lens; EFL=32mm; NA=0.7 Uncoated

The 13-505 45mm Dia. S-LAH64 NIR Aspheric Lens is a high-quality optical component designed for near-infrared (NIR) applications. Sourced from the renowned vendor Edmund Optics, this lens boasts a catalog number of 13-505 and is available for purchase through their official website.

This lens is characterized by its circular base shape and aspheric design, which allows for superior optical performance compared to traditional spherical lenses. The lens is made from S-LAH64, a specialized material from Ohara, which is particularly suited for NIR applications due to its low dispersion and high refractive index.

The lens has an effective focal length (EFL) of 32mm, making it suitable for medium-range optical systems. The numerical aperture (NA) is 0.7, indicating a wide acceptance angle and high light-gathering capability. Notably, this lens is uncoated, which means it does not have any anti-reflective coatings. While this may result in higher reflective losses, it can also provide greater design flexibility and cost savings.

The lens has an outer radius of 0mm, indicating a planar surface, and an inner radius of 0mm, suggesting a meniscus lens. The diameter of the lens is 45mm, and it has a thickness of 3.02mm at the edge and 13.9mm at the center. The front surface of the lens has a radius of curvature of 24.86mm, while the second surface is flat.
