Description
General Introduction: Near infrared (NIR) achromatic lenses are designed to provide the smallest possible spot size for polychromatic light between 750 and 1100nm. Near infrared IR lens group can reduce spherical aberration and has better performance when the monochromatic light source wavelength is 2um. Typical applications of these lens groups include: near infrared CCD imaging lens, near infrared laser convergence and inclusion lens, optical fiber and led focusing and calibration lens.
