Magnification is the ratio of the desired output beam diameter to the input beam diameter. Ensure your chosen expander can handle the input beam size without clipping.
Laser Beam Expanders Component Intelligence
Precision optical assemblies for laser beam diameter control and divergence management.
What are Laser Beam Expanders components?
Beam expanders are critical optical assemblies used to increase the diameter of a laser beam while reducing its divergence. Selection depends on the required magnification, input/output aperture, operating wavelength, and the need for fixed versus variable zoom capabilities.
How to Choose Laser Beam Expanders Components
Selecting the correct beam expander requires balancing optical performance with physical constraints.
Magnification Factor
Determine the ratio of output beam diameter to input beam diameter required for your specific focal spot size.
Wavelength & Coating
Ensure the optical coatings are optimized for your laser's specific wavelength to prevent damage and maximize throughput.
Aperture Constraints
Match the input aperture to your laser beam diameter to avoid clipping, which causes diffraction and power loss.
Fixed vs. Variable
Choose fixed expanders for stable, high-precision applications; use variable zoom for systems requiring adjustable beam profiles.
Wavefront Quality
Verify the transmitted wavefront error (TWE) specifications to ensure the beam quality remains high after expansion.
