DataRay CMOS Cameras and UV Light

UV |October 10, 2016

Although in the past DataRay CMOS beam profiling cameras were listed with a wavelength range of 355-1350 nm due to assumed sensor deterioration by short wavelength light, recent testing has demonstrated the CMOS sensor can image ultraviolet (UV) light down to 266 nm without sensor degradation; in this blog post we describe the test results.

Scanning Slits vs. Cameras

Beam Profiling Concepts |August 4, 2016

Our customers often ask us what type of beam profiler they should use to measure their laser beam(s). In this blog post, we explain the relative advantages and disadvantages of a scanning slit profiler and a camera-based profiler.

Why We Tilt Our Filters

Beam Profiling Cameras |July 21, 2016

In this blog post, we explain why tilting our filters is necessary for an accurate beam measurement.

M² Measurement

M Squared |April 12, 2016

As leaders in the laser beam profiling business, we have worked with M² for decades. In this blog post we discuss M², when to use it, and the way it is measured.

CMOS vs. CCD Sensors

Beam Profiling Cameras |March 29, 2016

CMOS and CCD image sensor technology was developed in the 1960s. Although for the last forty years CCD sensors have dominated the market, improvements in CMOS sensor design have catapulted them to a growing market share and the CMOS seems poised to replace the CCD in many applications.

Small Beam Width Theoretical and Experimental Error

Beam Profiling Concepts |March 14, 2016

One of the most important measurements in laser beam profiling is the beam width measurement. A common question we see is “How small of a beam can I measure with this camera?”
