This lens is characterized by its circular base shape and uncoated surface. It has a diameter of 15mm and a center thickness of 5mm, with an edge thickness of 1.5mm. The effective focal length (EFL) of this lens is 11.25mm, making it suitable for a variety of optical applications.

The lens's geometry is defined by several key parameters. The inner radius is 0, while the outer radius is also 0. The front surface has a radius of curvature (R1) of 8.58mm, with no curvature on the rear surface (R2). The back focal length (BFL) is 7.88mm. The lens's numerical aperture (NA) is 0.67, indicating a wide acceptance angle and high light-gathering capability.

The lens's shape is aspheric, which means it has a non-spherical surface to correct for spherical aberration and provide superior image quality. The lens's coating is not specified, indicating it is likely uncoated. However, this does not affect its performance in the specified wavelength range.
