Description
DataRay Inc. offers Beam'R2 Single Plane Scanning Slit Beam Profiler providing affordable, compact, and precise beam profiling with resolutions down to 0.1 um. These laser beam profilers can be used with a wide variety of laser sources.
DataRay’s Beam'R2 is well suited for many laser beam profiling applications. With both standard 2.5 µm slits and larger knife-edge slits, the Beam'R2 is capable of measuring beams with diameters as small as 2 µm. With options for both silicon and InGaAs or extended InGaAs, the Beam'R2 can profile beams from 190 nm to 2500 nm. Scanning slit instruments offer much higher resolution than camera based systems.

DataRay’s BeamMap2 represents a radically different approach to real-time beam profiling. It extends the Beam'R2’s measurement capabilities by allowing for measurements at multiple locations along the beam’s travel. This real-time slit scanning system uses XY slit pairs in multiple z planes on a rotating puck to simultaneously measure four beam profiles at four different z locations. The BeamMap2’s unique, patented design is most advantageous for real-time measurement of focus position, M2, beam divergence and pointing.
Beam’R2™ single plane XY scanning of 2.5 & 25 um slit pairs (5 & 50 um for longer wavelengths). High dynamic range Slit mode plus 0.1 um resolution
Knife-Edge mode, in one head:
Linear & log X-Y profiles, centroid
Resolution 0.1 um
Beams diameters 2 um to 4 mm. Auto-zoom on profiles. Auto slit width compensation.
Detector options, 190 nm to 2.5 um
BeamMap2™ adds multiple z-plane scanning to allow the measurement of:
XYZ profiles, Focus position & diameter
Real-time M2, Divergence, Collimation
By measuring in multiple planes in z, the propagation direction, BeamMap can identify the focus position with ±<1 um repeatability. This dramatically speeds up real-time diagnosis of focusing and alignment errors & the setting of multiple assemblies to the same focus.

True 2D™ Slits:
Profile tightly focused beams more accurately with thin, True2D™ slits. 0.4 um thick metallic multilayer films on a sapphire substrate avoid the tunnel effect of air slits. Air slits are frequently deeper than they are wide, and can buckle under high irradiance.
