The Intellium™ PDI is a state-of-the-art point-diffraction interferometer that generates its own reference spherical wavefront using a pinhole in a waveplate. The results are highly stable interferograms simultaneously phase-shifted using ESDI's HyperPhase™ module. The instrument measures real-time interferometric laser beam wavefronts at resolutions up to 1024 x 768.

Applications

• Wavefront and collimation testing of telescopes and periscopes
• Test laser diodes at wavelengths from 480 to 1800nm
• Test beams from 5-25mm diameter
• Alignment and collimation of fiber optic systems
• Optical alignment of holographic storage & disk mastering systems
• OEM integration for real-time monitoring of laser collimation
• Atmospheric testing
• Adaptive Optic Measurements/Applications

Main Features & Benefits

• Measure collimation to better than 100-200 micro radians (wavelength dependent)
• Wavelengths from 480-1800nm
• Small beam probe allows measurement between optical components.
• Simple operation reduces alignment time to minutes
• Using the HyperPhase™ module for simultaneous phase-shifting
