Wavefront Sensor

All-In-One Laser Beam Profiler & High Resolution Wavefront Sensor

High Resolution CCD Beam Profiler
Instant Beam Propagation & Wavefront Analysis
One Shot M2 Measurement

The BeamWave sensors deliver intensity and wavefront measurements simultaneously in an all-in-one device. Instead of using microlens array for wavefront sampling, these sensors are based on Digital Wavefront Technology ®, hence the number of wavefront measurement points is only limited by camera resolution providing a high spatial resolution wavefront, These sensors are typically used for either simultaneous laser beam profiling and beam propagation analysis or high resolution wavefront measurement for optical elements characterization.

With no moving parts or additional accessories, BeamWave® performs all critical laser beam measurements including intensity distribution, wavefront and beam propagation parameters.

High Resolution Beam Profiling

• Intensity distribution
• XY Profile
• Centroid
• Divergence angle
• Asymmetry
• BeamWave is a reliable CCD beam profiler for pulse & CW laser offering high dynamic and resolution for accurate intensity analysis.

Real Time Wavefront Measurement

• Zernike Analysis
• Low and high Order Aberrations
• Astigmatism
• BeamWave provides high resolution wavefront data, these useful parameters allows laser beam analysis in its all dimensions.

On Click Beam Propagation Analysis

• One Shot M²
• Intensity distribution at any selected plane
• Divergence angle
• Rayleigh Range
• Thanks to it capability to measure simultaneously phase and intensity, BeamWave delivers beam propagation analysis, thus providing an instant picture of laser beam behavior along the propagation axis.
• Beam propagation parameters, relative power density, wavefront, and intensity in any plane are measured with the same device.No mechanical mounts, stepper motors or moving stages. No maintenance cost of moving devices. No mechanical adjustments during lifetime of the instrument. No bulky systems for measuring several parameters are needed.

Simultaneous high‐resolution intensity & wavefront

• Acquisition of intensity is made directly on CCD chip, reconstruction of wavefront is performed by software.
• No need to acquire a two distinct instruments (beam profiler & wavefront sensor) to obtain same measurement
• Detailed profile of the beam in an arbitrary plane

One shot M² measurement of both CW and pulsed lasers

• Calculation of M², divergence, collimation and other beam propagation parameters of both CW and pulsed lasers is made by software.
• No need of additional instrumentation, saving time and costs
• Measurement are highly repeatable
• Measurement of even misaligned lasers are performed

Instant measurement of the entire beam over the broad range around focal region

• Beam propagation computed by software from simultaneous intensity and wavefront acquisition.
• Save time for laser beam adjustment
• Predictive laser beam analysis

BeamWave sensors come with GetLase® GUI software for Instant diagnostic of all laser beam parameters and GetWave ® GUI software with comprehensive wavefront analysis tools including, Zernike, MTF and PSF. GUI software XP, Vista and Windows 7 compatible, performs intensity and wavefront acquisition in a remarkably fast and easy way and provides comprehensive tools for beam profiling including intensity distribution and beam propagation parameters.
