37-418 15mm Dia. N-SF6 Precision Aspheric Lens; EFL=9mm; NA=0.83 Uncoated

The 37-418 is a high-precision aspheric lens, 15mm in diameter, with a numerical aperture (NA) of 0.83, making it an ideal choice for applications requiring high resolution and contrast. This lens is made from N-SF6 Schott, a high-refractive index glass, which contributes to its impressive light-gathering capabilities.

The lens features an effective focal length (EFL) of 9mm, providing a compact solution for imaging systems. Its uncoated surface ensures high transmittance across a wide spectrum, although it may be more susceptible to surface reflections compared to coated alternatives.

The geometry of the lens is carefully designed with an inner radius of 0mm and an outer radius of 0mm. The lens has a thickness of 5.28mm at the edge and 9.7mm at the center. The front surface of the lens is defined by an aspheric surface with a conic constant of -1.008508 and a series of aspheric coefficients.

This lens is particularly suitable for applications where a high numerical aperture and a compact form factor are required. However, it's important to note that the uncoated surface may require additional considerations for applications involving extreme light levels or specific wavelength ranges.
