Shanghai Optics Inc's custom beam expanders are used in many applications such as laser ranging, laser illumination, interferometry, etc. In high-power laser systems, beam expanders are used increase the beam area without significantly affecting the total laser energy. This results in a reduction of the laser power density which reduce the risk of damaging the coatings and optical materials of optical components. In a laser ranging system, a beam expander is used to minimize the laser divergence, resulting in a smaller collimated beam at a long distance.

Available in singlet, doublet (positive and negative focal lengths) and triplet varieties, Knight Optical can supply customised beam expanders for a range of laser-based, cutting-edge projects. Whether your application works in the ultraviolet (UV), visible, near-infrared (NIR), mid-infrared (MIR) or far-infrared (FIR) spectrum, opting for our custom-made components allows you to specify suitable substrates for your required wavelength.

Beam expanders are optical devices which increases the diameter of the input beam to produce a larger output. Used with collimated light, they have important applications in remote sensing, interferometry, and laser scanning.

Edmund Optics has a variety of beam expanders, including devices for different wavelength regions (e.g. Nd:YAG and CO₂), rotating or non-rotating optics for divergence adjustment and research-grade devices.

Photonic Devices' precision Galilean beam expanders have been sold globally for over 20 years and include an extensive number of standard models. These multi-element beam expanders have been computer-designed to provide excellent wavefront quality with minimum beam deformation. All lens elements are air spaced and the majority of models have variable air spacing for collimation adjustment. All lens surfaces have multilayer antireflection coatings, with power handling capabilities over 1 kW (> 200 W for beam expanders operating at 10.6 microns).

Optogama designes and manufactures laser beam expanders, beam reducers and divergence compensators which are used to increase or decrease laser beam diameter and control beam divergence:

• compact motorized laser beam expanders of MEX and MEX-V2 series
• high-power motorized beam expanders MEX-HP
• fixed ratio beam expanders FEX series
• variable beam expanders VEX and reducers VRE series
