What types of lenses are best suited to collimate and focus a diode laser?
Melles Griot offers collimating and focusing lenses designed specifically for diode laser wavelengths. The 06 GLC series lenses are designed and optimized for 405 nm, 633 nm, 780 nm, and 830 nm. They can also be used at other diode laser wavelengths and still provide excellent performance. Many of these lenses are diffraction limited: Spherical aberration, coma, astigmatism, and sphero-chromatism have been corrected by the design. These lenses are antireflection coated to provide increased performance.
