Laser Diode Collimators
Semiconductor lasers often require specialized lenses due to their unique characteristics. In general, laser diodes are small point sources with large numerical apertures. Laser Diode Objectives are designed to accommodate the large input angles associated with these compact laser sources. Standard designs offer diffraction limited performance for numerical apertures as high as 0.6, making them useful for fiber optic coupling or collimating. The spectral range of our Diode Collimators is extended into the infrared region allowing for operations with most diodes within the 670 nm to 1550 nm wavelength range. The lenses may also be combined to produce focusing or non-focusing configurations as desired. Though designed for use with Diode Lasers, these lenses may be used with other lasers requiring highly corrected lenses within the visible and near infrared spectral range.
