High-resolution SWIR laser beam profiling system for applications in the 900 nm to 1700 nm wavelength range.
This 14-bit, large area, uncooled InGaAs camera provides user programmable integration and incredibly fast capture rates with an optical dynamic range of greater than 1000:1.
With an ultra-compact design and the convenience of a single USB cable for connectivity, this new camera will handle the demanding requirements of laboratory applications, production environments, and along with most any field service requirement.

The latest release of the BeamView-USB 4.4 software includes several new features that extend the analytic capabilities of the LaserCam-HR laser beam diagnostic systems. Unique features of BeamView-USB software that were not included in the Digital or Analog BeamView software platforms.
Flat Top Beam Analysis
Six additional calculations are now available with BeamView-USB for flat top beam analysis. These calculations are based upon the ISO 13694:2000 standards. The following calculations will allow for greater flexibility for the analysis of applications involving flat top beam shapes. These BeamView-USB calculations may assist in the analysis of Excimer and Nd:YAG laser customers looking to analyze beam uniformity in the near field. The six new features are:
• Plateau Uniformity
• Flatness Factor
• Edge Steepness
• Beam Uniformity
• Effective Irradiation Area
• Effective Average Power/Energy Density
Adjustable Trigger Delay
An adjustable Trigger Delay feature has been added to BeamView-USB 4.4 allowing for a delay to be added (µseconds) to the default trigger delay of the LaserCam-HR camera. This will assist in beam capture when the laser is fired after an external trigger signal that is shorter than the default camera trigger delay. Depending on the default trigger delay of the camera (150 µsec for the CMOS camera types and 20 µsec for the InGaAs LaserCam-HR) and the repetition rate of the laser, the trigger delay feature assists in assuring that a valid laser pulse is captured on the camera during the cameras exposure time.
The LaserCam-HR and LaserCam-HR-UV have a default integration time of 10 msec and the LaserCam-HR-InGaAs camera is set to a default value of 1 msec for optimum performance.
