These aspheric lenses are made from D-ZLAF52LA CGDM, a specialized glass material known for its optical properties. The lens has a diameter of 7.2 mm and a thickness of 1.282 mm at the edge, while the center thickness measures 1.947 mm. The effective focal length (EFL) is 11 mm, making it suitable for applications requiring precise focus and magnification.

The lens features an aspheric shape, which is designed to reduce spherical aberration and improve optical performance. The front surface of the lens has a conic constant of -0.905894, while the back surface has a conic constant of approximately -3.790758e-05. The lens's numerical aperture (NA) is 0.3, indicating a wide acceptance angle and high light-gathering capability.

Please note that the lens does not come with any coating. Coatings can be applied to enhance the lens's performance, such as improving transmission, reducing reflection, or protecting the lens surface. However, this particular model is uncoated, offering a bare, unaltered lens surface.
