Aspherical cylindrical lenses are essential components in optical systems, particularly in the collimation of laser diodes. Unlike spherical lenses, aspherical lenses offer superior performance by correcting spherical aberrations, resulting in enhanced beam quality. As laser diodes often emit light that is not perfectly collimated, these lenses are View More
