Low price aspheric lens

Dec 20,2022

Spherical aberration calibration. Low price aspheric lens is used to replace the spherical lens, the most significant advantage is that it can correct the spherical aberration caused by the spherical lens in the collimation and focusing system. By adjusting the surface constant and aspheric coefficient, Low price aspheric lens can eliminate spherical aberration to the greatest extent.

Low price aspheric lens
Low price aspheric lenses can converge light to the same point, provide optical quality, and basically eliminate the spherical aberration produced by spherical lenses (light rays converge to different points, resulting in blurred images).
Three spherical lenses are used to increase the effective focal length and eliminate spherical aberration. However, with a Low price aspheric lens, its high numerical aperture and short focal length can be achieved, and it simplifies system design and improves light transmittance.
Through the above introduction and analysis of the Advantages of Low price aspheric lens, hope it helps you.
