Beamage-4M User Manual Revision 1.0 7
1. BEAMAGE-4M
1.1. INTRODUCTION
Gentec-EO introduces the new Beamage-4M. Its sleek and thin design allows the Beamage-4M to fit
between tight optical components. Its USB 3.0 connection and improved algorithm allows very fast frame
rates. The new 4.2 MPixel CMOS sensor has a large 1” optical format with a small 5.5 µm pixel pitch
allowing high resolution on large beams. Most importantly the innovative and improved PC-Beamage-4M
software is simple and intuitive to any new or expert beam profiling user.
1.2. SPECIFICATIONS
The following specifications are based on a one-year calibration cycle, an operating temperature of 18 to
28°C (64 to 82 F) and a relative humidity not exceeding 80%.

Windows 7 (for optimal performance)
Windows Vista
Average RAM Allocation 500 MB
Up to 1250 MB for 64 images in buffer
Recommended Requirement
4 Gb RAM minimum
8Gb RAM for optimal performance
Intel i series processors (i3, i5, i7) or equivalent for optimal
performance, other processors will have lower specifications.
i7 for optimal performance
Beamage-4M is a new and a high end product. It needs an equally
recent high end computer to work. Computer hardware must be from
2010 or after. No computer or parts bought before 2010 will be
supported
For Optimal Performance
Close all programs except the PC-Beamage-4M;
Keep a minimum of 1 GB RAM free when running the PC-
Beamage-4M;
Keep a minimum of 50% of free CPU power when running
the PC-Beamage-4M
Use an Image Buffer of 1
Multi Camera
Recommendations
When working with more than one camera, we strongly
recommend using one USB3.0 port per camera and a recent
high end computer for optimal performance
