Our entireZemax Catalog is also available.These Galilean Beam Expanders provide an ideal solution for expanding or reducing beam diameters. They are also commonly used to reduce divergence,which will decrease by the same factor that magnification is increased. Another common use is to expand the beam and then focus with another lens to takeadvantage of a reduction in spot size. These beam expanders have all been designed to minimize the telescope length, minimize the introduced wavefronterror ( λ/4), and provide diffraction-limited performance (for Ø1 mm input).The design incorporates a plano-concave singlet to provide the desired divergence and a doublet, which has been computer optimized to balance aberrationsand re-collimate the beam. The rotary barrel controls adjustment of the diverging lens with graduations in 50 µm increments. All of the designs are availablewith a broadband antireflection coating for the 400 - 650 nm (-A), 650 - 1050 nm (-B), or 1050 - 1620 nm (-C) wavelength range.Thorlabs also offers many other types of beam expanders, including variable beam expanders whose expansion ratio is achieved via rotation and fixed beamexpanders with a sliding collimation adjustment mechanism.

Thorlabs.com - Optical Beam Expanders: Beam Expansion or Reductionaperture is threaded to provide compatibility with our externally threaded SM05 (for BE02M, BE03M,and BE05M) or SM1 (BE10M, BE15M, and BE20M) products. As a result, these beam expanders canbe used with many of our kinematic mounts, lens holders, iris diaphragms, and other optomechanics.The image to the right shows the beam expander mounted in a KM100 kinematic mount. A mountingring allows the beam expander to be secured into 1" or 2" mounts. The BE02M, BE03M, and BE05Mcan be used with our KS1, KM100, or FMP1 mounts. The BE10M, BE15M, and BE20M have a 2"mounting ring that is compatible with mounts such as the KS2 or FMP2.The image to the left shows the fixed post-mounting configuration available with these beam expanders. 4-40 and M3 tapped holes are provided on theBE02M, BE03M, and BE05M, while the BE10M, BE15M, and BE20M models have 8-32 and M4 tapped holes.Hide 5X20XØ8.0 mmØ8.0 mmØ4.6 mmØ4.6 mmØ4.6 mmØ4.6 mmØ4.0 mmØ4.5 mmØ2.5 mmØ2.0 mmØ1.6 mmØ1.2 mmInput ThreadSM05SM05SM05SM1SM1SM1Output ThreadSM1M36 bM36 bSM2SM2SM2KS1 / MSP1KS1 / MSP1KS1 / MSP1KS2 / TR2KS2 /TR2KS2 / TR2N-BK7, N-SF5N-BK7, N-SF5ExpansionInput ApertureMax.

Hide Wavefront DataWAVEFRONT DATALeft: Typical wire grid plot of the wavefront distortion of a Gaussian beam that haspropagated through a BE series Gaussian beam expander. See the table below forthe calculated peak-to-valley wavefront distortion value and the RMS wavefrontdistortion value for each BE series beam expander at its design wavelength.Thorlabs' BE series of beam expanders are specified to provide diffraction-limited performance, which means that the introduced wavefront distortion in aGaussian beam will be less than λ/4. However, the nominal performance of the BE series of beam expanders is typically much better than this specification.Below is a table that lists the calculated wavefront distortion for each BE series beam expander and the parameters of the beam used to make the calculation.The beam is normally incident on the beam expander and the propagation direction is such that the output beam is larger than the input beam.
