At very low powers the zero offset becomes important. This means that the sensor reads some value even if there is no input into it. This can be because of external heat sources or the fact that the meter is not zeroed properly. Now say that there is a zero offset of 10mW = 0.01W. If we are reading a laser of 10W, then the meter will read 10.01W, an additional error of 0.1%, very small. But if we are trying to measure 0.1W, then the reading will be 0.11W, an error of 10%! This is illustrated in the diagram below...
A common concern that I have heard throughout my years with Ophir-Spiricon is that many people do not understand the necessity of calibration. They do not understand what the calibration process entails, and how it can save them money, time, and frustration.
Our products are used throughout the world in many different areas, from medical and scientific processes to defense and industrial applications. With each application there are different usage parameters; however, one thing that remains consistent no...
Absorptive glass filters have varying degrees of non-trivial fluorescence, which can be problematic in some applications. Here’s a fairly simple way to check if a filter is fluorescing:
- Place the filter in a collimated beam with a power meter behind it, located very close to the filter and measure the signal.
- Increase the distance (>> 10x the beam diameter) from the filter to the power meter and measure again the signal..
BeamGage is a multiple process application with three process types which run when BeamGage is operating: Spiricon.ConsoleService.exe, Spiricon.DataServer.exe, and Spiricon.Version5.exe. These processes can be viewed in Windows Task Manager under the Processes tab.
Spiricon.ConsoleService.exe is a Windows service process that launches the BeamGage connections to cameras. Spiricon.DataServer.exe is the process which acquires data from cameras. Spiricon.Version5.exe is the main BeamGage...
Is it possible to image a UV laser with a Silicon Sensor CCD camera offered by Ophir-Spiricon? The answer is yes, but the direct UV light ablates Silicon CCD chips over time. The ablation is cumulative and depends on the intensity, the wavelength, and the duration of the light on the sensor. The best choice for imaging UV light without damage is to avoid directly imaging the beam on the CCD sensor by using an UV image converter...
Measuring the performance of a laser has possible for a number of years and is accomplished with a variety of techniques. These electronic laser measurement solutions give the laser user more relevant, time-based data that shows trends in laser performance rather than single data points. While these solutions have provided laser users with the ability to present data in a simple and easy to understand manner, the application of the data still seems to be unclear to many laser users.
- How often should data be collected?
- What measurements...
Abstract
The discovery of Rayleigh Scattering by 3rd Baron Rayleigh, John William Strutt, served an explanation of why the sky is blue during the daytime and different hues of orange, pink, and purple in the early morning hours and at dusk. But it was only recently that this phenomenon has been applied to the measurement of high-powered lasers. Only through the measurement of the laser source and laser system can the user of the laser fully understand its performance and then start to control the processes in which they...

The NanoScan 2s is the newest scanning slit, sensor-based, beam profiling system from Ophir-Spiricon LLC. It can profile pulsed laser beams with repetition rates in the 10 kHz range and above. To enable the measurement of these pulsed lasers, the profiler incorporates a "peak connect" algorithm...
Question: How can I be certain that my Beam Profiler is measuring accurately? Is there a standard calibration methodology?
Answer: There is no calibration standard from which one can verify their camera based beam profiling measurement accuracy. Spiricon has done the next best thing to provide customer confidence in reliable and consistent results from its camera based profilers. The issue can be broken down into two major areas; 1) the input (camera), and 2) the output (from software algorithms...
To handle a beam who’s power is unstable, you’ll first need to observe the behavior of the readings. Unstable power can take two forms:
1. Fluctuations , where the time constant is short,
2.Drift, where the time constant is longer...
Each Ophir power/energy sensor is provided with a functional data sheet with helpful information about its particular operational parameters and specifications. Below the typical specifications are notes, in fine print, partly because there is quite a lot of really useful information contained therein that is being sized to fit on one page. These notes are categorized as Notes: (a) (b) (c) (d) …etc. corresponding to their particular specification association.
These notes are very...
BeamGage does have the ability to run multiple instances while connected to the same camera source, which can add benefits such as simultaneous mutually exclusive results. For instance, you can display the Beam Width Major and minor result along with the Beam Width X and Y result, which on one instance of BeamGage is a one or the other limitation. Additionally through automation, the results from the multiple instances could be acquired simultaneously thus expanding the potential utility of the BeamGage application...

Over the years, different approaches have been used to heat treat metals, typically relying on large furnaces where an entire object is subjected to the heating process. This method can consume substantial amounts of energy and is not a useful approach when attempting to heat treat a specific area or portion of the equipment. The use of lasers to perform this heat treating process has become a well-accepted approach. Understanding the beam shape, the uniformity of its intensity, and the cleanliness of...
echnological advancements in laser sources and the systems in which they are integrated have provided the industrial laser user with higher quality and more consistent laser processes. Laser OEMs and systems integrators continue to make improvements in their products and services thanks to partnerships with system component manufacturers, laser applications development houses, and end users...
Because a laser beam provides a vehicle for delivering energy in such a precisely controlled way, and without physical contact, it’s not surprising that the laser has found so much use in medical applications.
It’s used as a surgical tool (Fig. 1), cutting through various types of tissue in place of the traditional scalpel, and simultaneously cauterizing blood vessels as it goes, so that bleeding is minimized. In some ophthalmological applications, an Excimer laser beam cuts tissue using non-thermal mechanisms based on the physical nature of short wavelength UV radiation.

High power laser systems are making their way into more and more industrial applications. From cutting steel, to drilling via holes in silicon, to marking plastic, a whole range of processes now make use of the laser to produce results not previously practical. Advances in fiber lasers in particular, with their scalability, beam quality and wall-plug efficiency, have made laser beams with powers of many tens of KW a common tool available to commercial users. Even...

Acrylic Mode Burns have historically been universally used because they are the lowest cost alternative to the budget-minded end user. This method, however has been cited for producing dangerous, cancer-causing airborne materials, and is not a real time technology. On the other hand, Real-time beam profiling has been historically too expensive for the average user to acquire.
We discuss a new technology that enables the design of a new low-cost real time CO2 high power beam profiler that is within...
