Description
The aspherical lens's unique aberration-correction design empowers it to execute highly efficient and accurate collimation of light beams. As a result, the energy of the output light beam assumes a Gaussian distribution. Both surfaces of the lens are coated with anti-reflection films, that significantly decrease surface reflection losses and substantially improve the light transmittance. Nevertheless, the aspherical lens possesses certain inherent characteristics. Specifically, it exhibits a chromatic aberration phenomenon, with a strong correlation existing between its effective focal length (EFL) and the wavelength. During the manufacturing, the relative positioning of the lens and the optical fiber has undergone extremely precise adjustments. This ensures that the deflection angle of the emitted light beam is maintained within an exceedingly narrow range of 0.5 degree. Consequently, it is better equipped to adapt to diverse application scenarios and system requirements.
