Pulsed Lasers: Pulse Energy & Imager Gain

Posted by Loren Jones on 1/10/2017 to General

This is the third entry in a series of blog posts that explore DataRay’s pulsed laser measurement capabilities. The previous blog posts provided an overview of pulsed lasers and covered how individual pulses can be measured using Auto-Trigger mode or External Trigger mode to synchronize exposures to single pulses. This blog post will talk about the energy requirements involved with measuring pulsed lasers, and how the received signal can be controlled when the exposure time is fixed.

Pulsed Lasers and External Trigger Mode

Posted by Loren Jones on 12/2/2016 to General

In our previous blog post, we provided an overview of pulsed lasers and how the exposure time of a camera must synchronize with a laser pulse to provide an accurate measurement. We talked about how Auto-Trigger Mode can be used to measure pulsed lasers with no formal synchronization by setting an appropriate exposure time and rejecting partial pulse captures. This blog post will now talk about how an external trigger can be used to formally synchronize the exposure time to the pulse width. This External Trigger mode provides more versatile and precise measurements of pulsed lasers.

Pulsed Lasers and Auto-Trigger Mode

Posted by Loren Jones on 11/21/2016 to General

DataRay has long offered products with the capability of measuring pulsed lasers in addition to continuous wave (CW) lasers. This blog post will review how capturing pulsed lasers with a camera beam profiler differs from capturing CW lasers, and how the additional challenges with pulsed lasers are handled to provide useful measurements with the software’s Auto-Trigger mode.

Line Laser Profiling System

Posted by Loren Jones on 11/3/2016 to General

DataRay has always been committed to providing accurate and reliable solutions for characterizing a wide range of laser beams. We take pride in listening to customer requests and working to expand our product line to meet their needs. DataRay is happy to announce our new Line Laser Profiling System (LLPS) with the capability to provide direct measurements of line lasers up to 200 mm in length and down to 55 microns in thickness.

DataRay CMOS Cameras and UV Light

Posted by Lucas Hofer on 10/10/2016 to General

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.

When to Use the D86 Beam Width Measurement Method

When to Use the D86 Beam Width Measurement Method

Although the clip level method and the second moment method are the most popular methods of beam width measurement, other beam width measurement techniques such as the D86 method can be used with beam profiling cameras. Rather than using the 1D or 2D profile of the beam to determine the width, the D86 method uses the diameter of a 86.5% power enclosure as the beam width. In this blog post we describe the D86 beam width measurement method and the applications for which it is most appropriate.

Tutorial: Interfacing to C++ in Visual Studio 2013

Tutorial: Interfacing to C++ in Visual Studio 2013

It is our pleasure to announce a new Visual C++ tutorial for interfacing DataRay Camera and Slit Scan Profilers using the DataRay OCX. The DataRay OCX is an ActiveX component that can be accessed from a variety of Windows based environments. It includes ActiveX controls that allow users to build an interface that is capable of sending and receiving data from the DataRay software. The OCX is automatically generated and registered with the Windows operating system upon installation of the standard DataRay software. Complete documentation of the DataRay OCX is available for reference. Before writing an interface using the DataRay OCX, we recommend that you learn to use your beam profiler in the standard DataRay software.

Scanning Slits vs. Cameras

Posted by Lucas Hofer on 8/4/2016 to General

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.

Large Beam Measurement System

Posted by Lucas Hofer on 7/7/2016 to General

Although most laser beams can be imaged directly onto an image sensor, occasionally our customers need to measure beams which require a larger sensor area. For beams too large for traditional approaches, DataRay is pleased to announce our new Large Beam Measurement System (LBMS). Read on to learn more!
