Buying Laser Diode Collimators

Your Custom Optics Expert

Shanghai Optics provide many different types of standard collimating lenses, including aspheric and achromatic lenses for many different light sources such as highly divergent laser diodes. Our standard collimating lenses can convert divergent laser beams to well-collimated laser beams that enter beam expanders for interferometry, laser material processing and laser scanning applications.

We also provide custom collimating lenses for projecting a source at infinity for infinite conjugate testing of optical systems. The collimating lenses can consist of several optical elements. The selection of optical materials and optical configuration depends on the entrance pupil diameter, wavelength, focal length, and field of view of the optical system under test.

PowerPhotonic manufactures a large range of high-power diode laser optics for diode bar and diode stack correction applications. Our slow-axis-collimator (SAC) optics minimize the slow-axis divergence of diode laser bars and stacks. Our SACs can also be designed with built-in smile correction. For Fast Axis Collimation, we can provide fast axis collimator arrays, with either fixed or matched pitch. Additionally, we have a range of high power diode correction optics that can be customised as a result of wavefront analysis.

Avantier offers a range of standard collimating lenses, including aspheric and achromatic lenses suitable for highly divergent laser diodes. These lenses convert divergent laser beams to well-collimated beams for use in laser scanning applications, laser material processing, and interferometry with beam expanders. We also provide custom collimating lenses with multiple optical elements that project a source at infinity for infinite conjugate testing. Selection of optical materials and configuration is based on various parameters like entrance pupil diameter, wavelength, focal length, and field of view.
