Collimating lenses are essential in fiber optics, ensuring light is efficiently coupled into fibers and transferred across optical systems without significant loss, this is crucial for high speed data transmission in telecommunications
A laser collimator works by coverging a divergent beam, by one or a group of positive focal length lenses such as plano convex lens or double convex lens, to make the beam be collimated to the optical axis
CCRQ types of collimating lenses
spherical lenses: such as plano convex lens, double convex lens or meniscus lens, low cost,but subject to spherical aberration and limited collimation accuracy
Aspheric lenses: perfectly correct spherical aberration and are the mainstream choice for achieving diffraction limited colimation
Achromatc lens groups: by combing lenses makde of different dispersive materials, they correct chromatic aberration caused by changes in refractive index with wavelength, suitable for multi wavelength systems
