Features
BeamGage® Laser Profiling Software
BeamGage® comes in two versions: Standard and Professional. Each builds off of the next adding additional capability and flexibility as needed for adapting to almost any configuration requirement. The software performs rigorous data analyses on the same parameters, in accordance with the ISO standards, providing quantitative measurement of numerous beam spatial characteristics. Pass/Fail limit analysis for each of these parameters can be also applied.
Laser Beam Profiler Accessories
When performing beam profiling measurements on a laser, it is sometimes necessary to manipulate the beam in order to achieve a signal that is suitable to be measured. Occasionally, the beam needs to be sized correctly by either increasing it if it is too small, or increasing it if it is too large. Often times, the laser’s power needs to be reduced to a certain level to be imaged. Our laser beam profiler accessories allow you to achieve proper beam sizes and power levels so that you can achieve the most accurate measurements possible.
Designing Laser Beam with BeamMaker
BeamMaker helps engineers, technicians, and researchers understand a beam's modal content by creating a theoretically generated beam. Design your perfect beam profile in BeamMaker by specifying the mode, size, width, height, intensity, angle, and noise content - then configure your laser to run the as designed, and compare your actual beam to the theoretically derived measurements. The end result is knowledge about how much the real beam varies from the desired beam.
Fundamentals of Laser Measurement & Beam Profiling
Is your laser's beam profile shaped correctly for your application? This video teaches the fundamentals of laser beam profiles and discusses the benefits of profiling your laser beam. Several case studies are presented showing before and after laser beam profiles.
Measuring Laser Focus Spot Size in an industrial Medical Device Application
This step-by-step tutorial will show you how to set up a camera-based beam profiling system on an industrial single-pulse laser welding system. It will also demonstrate for you how to simultaneously analyze the laser's focused spot, measure the laser's energy per pulse, and measure its temporal pulse shape.
Frequently Asked Questions
- What are the key differences between CQD and InGaAs beam profiler cameras?AnswerCQD cameras cover the NIR and SWIR range (900–1700 nm) and extend into the visible spectrum (400–900 nm), offering broader spectral coverage than InGaAs. While InGaAs provides higher quantum efficiency in SWIR, CQD cameras offer sufficient sensitivity for applications such as laser beam profiling, telecommunications, and LiDARs. They also support higher frame rates, making them ideal for dynamic imaging applications.
- What if I want to measure the beam profile of a laser that is tightly focused to less than 150 mµ?Answer
For focal spots smaller than 150 µm, use the CQD camera in combination with the Ophir 4X Reimaging Beam Expander (PN: SPZ17022).
- What is the quantum efficiency response of the CQD sensor?Answer
The quantum efficiency (QE) chart:

"Please note that when using a combination of ND filters, the quantum efficiency (QE) chart must be adjusted to account for the transmission characteristics of the filters."

- When measuring a 1550 nm light source, what should I do if visible (VIS) light is interfering with my beam profile?Answer
Use an IR long pass filter that blocks all visible wavelengths, allowing only the NIR/SWIR light to pass through.
