Buying Beam Expanders

Top-level product category: optical components and devices

Related product category: beam collimators

Beam expanders increase the beam radius of a laser beam, facilitating long-distance transmission or allowing the beam to enter optical devices properly. They operate similarly to telescopes and can have a fixed or variable expansion ratio, making them versatile tools in laser optics.

Making Good Purchase Decisions

With its comprehensive resources, RP Photonics helps you to well prepare purchase decisions:

Aspects to Consider Before Buying

Some aspects to consider before buying beam expanders: expansion ratio, range of allowed input beam radii, optical quality, astigmatism, alignment and mounting options, power handling capacity, thermal stability, compatibility with laser systems, ease of integration, size and weight.

For responsible purchase decisions, we recommend applying good practices.

beam expanders

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.

beam expanders

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).
