Ophir models 5000W, 10K-W and Comet 10K are calibrated using relatively low power lasers ~ 150 - 300W. Using such low power lasers to calibrate the instrument vs. the high power at which the sensors are used raises the question of calibration accuracy. The following explanation clearly demonstrates that the 5000W, 10K-W and Comet 10K are indeed accurate to ±5% over their measurement range. The 5000W and 10K-W sensors work on the thermopile principle, where the radial heat flow in the absorber disk causes a temperature difference between the hot and cold junctions of the thermopile which in turn causes a voltage difference across the thermopile. Since the instrument is a thermopile voltage generating device, it must be linear at low values of output. Therefore, if it is shown to be linear at powers which are a significant fraction of the maximum power, it will necessarily be linear at very low powers and if the calibration is correct at low powers, it will remain correct at high powers as well. On the other hand, although the output may be linear at low powers, there may be a zero offset that, due to the relatively low output at low powers, will cause an error in calibration...
An integral part of the Ophir-Spiricon culture is an engendering of the practice of continuous improvement. We do this with one focus in mind: Customer Satisfaction. The question driving all of these improvements is, “What can we do to provide better service to our customers?” One element of this is captured in the development of a system to recognize the improvements made in the Calibration Department.
These improvements come from every person in the department, and are documented...
Watch the Fastest Calibration in the Industry
At Ophir-Spiricon, we realize that our customers are the lifeblood of our company. Because of this partnership, we are driven to provide quality products and services in the most cost-...
At Ophir-Spiricon we pride ourselves on providing quality in every step of our service to you. To validate and measure our commitment to quality, Ophir-Spiricon has recently renewed our ISO/IEC 17025:2005 accreditation by ACLASS. We validated that we are still in compliance for our calibration systems. ISO/IEC 17025:2005 is an accreditation that provides the general standards for testing and calibration labs worldwide. It helps us strive to complete consistent, valid results in our testing.

Spiricon has worked tirelessly over the course of the last several years to enhance the customer service experience and to continue to provide a quality service to our customers. With customer satisfaction one of our main objectives, we have developed processes at all levels that help us reach this goal. Our highly skilled technicians have been rigorously trained to ensure that each piece of equipment that is calibrated and repaired is done so with accuracy and efficiency, providing our customers better and more responsive service.
...At Ophir-Spiricon we have raised the standard of service. One of the pillars of our business model is customer satisfaction, and we firmly believe that the level of customer focus we provide makes us stand out in our industry.
The services provided by our Recalibration and Repair department have continually evolved to become what they are today. For your convenience, we have developed many “extras” and integrated them into a standard part of our service. Providing these extras as part...
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...
- 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...
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...
VIDEO: Online Calibration Portal
Ophir-Spiricon is proud to announce the release of our new online Calibration Portal. This portal will allow you to track the status of open RMAs and maintain calibration information for all equipment. You may access our Calibration Portal at http://calibration.us.ophiropt.com.

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 lock out controls and the modification of reported results through the Options Privileges feature.
In BeamGage, click on the Options button and then the Privileges item and the following dialog box will open. In order to access this privilege control, the user must be assigned Administrator privileges on the local...
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...
