BeamMap2 – Multi-Plane Scanning Slit Beam Profiler
OVERVIEW
Product Description: DataRay Inc offers the BeamMap2 providing affordable, compact, and precise beam profiling with resolutions to 0.1 um. These beam profilers can be used with a wide variety of laser sources from 190nm to 2500nm, depending on the model.
Beam’R2™ single plane XY scanning of 2.5 & 25 um slit pairs (5 & 50 µm 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.
[Protected under US Patent # 6,313,910.]
Configuration: All beam profiler systems comprise a compact, USB 2.0, port-powered head, 3 m cable and software for Windows XP & Vista.
True2D™ 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.
