Ophir's new IS1.5-VIS-FPD-800 is a multi-functional sensor that offers several advantages in a single instrument for measuring VCSEL's:
The world remains in a continuing state of uncertainty due to the new COVID-19 coronavirus. Face masks and disinfectants are selling very well. Disinfection with UV light could offer a way of disinfecting larger areas without the use of chemical disinfectants, especially in hospitals where patients are being treated.

There is little debate about how Additive Manufacturing is adding benefits and changing the face of manufacturing in our modern age. Additive Manufacturing allows for the manufacturing of more customized parts, using more specialized materials, and will eventually create a more localized, rapid, and agile distribution network than what have been used to.

But use of the technology associated with Additive Manufacturing does not come without challenges. The investment into Additive...

Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT relies on BeamWatch AM in laser beam melting (LBM) processes

The Fraunhofer Research Institution for Additive Manufacturing Technologies IAPT has set a goal for itself to automate additive production and use this technology to manufacture the products of tomorrow in a resource-efficient manner. A consistently high level of quality in the manufactured components is decisive for whether the laser-based...

To select the Ophir FluxGage model that will best suit your needs, first consider two questions: What size are the luminaires that you plan to measure (what is their light emitting surface size), and what is their expected luminous flux? The answers to these questions will help you find the right solution. The following table lists the specifications for each of the different FluxGage models:


Model name FluxGage 600 ...

When measuring average power using a photodiode detector such as PD300 or IS6-D-VIS, the maximum power or saturation power is determined by the maximal photocurrent that the photodiode can generate while still maintaining linearity. The saturation power is typically 3mW for a bare silicon photodiode. Adding attenuation in the form of a filter or through the use of an integrating sphere will naturally increase the saturation power of the sensor as a whole.


Terahertz (THz) applications - till recently mainly still in the R&D phase - are beginning to emerge into the light of the commercial and industrial day. So is the need to measure these THz beams.
Ophir offers several solutions for THz measurement, including sensors for measuring low powers (down to nanowatts), high powers (up to 3W), as well as profiling THz beams. Let’s have a look at how we calibrate the 3A-P-THz and RM9-THz sensors

Ophir BeamWatch Integrated - Surprisingly flexible

Does it make sense to use a laser measurement system with a laser that doesn’t fit the specification of the measurement device? Normally, we would answer this question with an emphatic “no”. Surprisingly, our customers, working with Ophir sales experts, discovered things are different with BeamWatch Integrated. At first, the goal of the Ophir BeamWatch non-contact measurement system was to measure Gaussian beam...

Measurement technology for lasers in medical applications

For any application, a focused laser beam should live up to previously defined specifications. But for medical technology, precise adherence to the parameters is of even greater importance. Both for regulatory and ethical reasons, the laser beam must be carefully tested throughout the entire value chain: from the development of the laser source to its application on the patient and/or production of medical products. Scrimping on...

LED and OLED technology for automotive

LED/OLED technology opens up completely new possibilities for automotive designers around the globe. At the same time, the era of autonomous cars attaches increasing importance to the lighting of both the vehicles and their surroundings. As the lighting possibilities grow more diverse, so do the demands on the quality of the LED luminaires used – and thus on the technology needed to measure them. While speed and reliability are of utmost...

In this Q&A with Mark Gitin, Senior Vice President and General Manager of the Light & Motion Division of MKS Instruments, and Christian Dini, Director Global Business Development, Ophir, they discuss that, with lasers there will always be opportunities for improvement. Reliable technology for measuring the laser beam can really help with process optimization.

Q. This year, the Laser World of Photonics show will focus on lasers for industry 4.0. Where do you see the most...

Designed to measure. Every laser. Everywhere
Laser measurement is now widely used in treatment of patients as well as in the manufacturing of medical products and instrumentation. Miniaturization, further enhancement of optical quality of different wavelengths, and new technologies with shorter laser pulses have led to a growing dissemination of laser systems
Because a laser beam provides energy in such a precisely controlled way, and without physical contact, it's not surprising that the laser has found...

1. Introduction
During the past decade laser power levels used in production applications has risen significantly. Today, welding systems are commonly using laser power in the range of multiple kilowatts. To deliver continuously high product quality, the key parameters of the laser beam must be measured on a regular basis. Ophir has tackled the task and developed a non-contact measurement technology based on the Rayleigh scattering. The technology used in the BeamWatch laser beam profilers enables the measurement of...

This document describes the inherent problems involved with measuring average power for low frequency pulsed laser sources, and describes the new “Low Freq. Power Mode” being offered on many Ophir devices and meters to solve these problems. It describes how to use the new mode and mentions some tips for obtaining best results.

VCSEL sources have become very popular in the last few years and are being used for many applications in...

Vertical Cavity Surface Emitting Lasers (VCSELs) are a type of semiconductor laser diode. Unlike edge emitting laser diodes, VCSELs emit upwards and thus can be easily packaged as emitter arrays containing hundreds of emitters on a single chip.

Other characteristics of VCSELs:

VCSELs were first used in the telecom industry, and today are widely used as light...

Lasers are increasingly deployed in manufacturing applications, being pushed to higher and higher output powers and smaller and smaller beam sizes to work faster and with higher precision. Determining the beam profile at the beam focus of these lasers is critical to verify and improve manufacturing product quality. However, there are enormous challenges that must be overcome to capture the beam profiling data.

Consider profiling a 150 micron beam at focus from a 4 kW laser. The power per...

For many people, it isn't clear why there is a need for calibration of measurement equipment. These laser users are not fully aware what the calibration process entails and how it can save them money, time, and frustration.

Ophir's laser measurement 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...

Interfaces for laser measurement technology

All the talk about digitization and ‘big data’ has made manufacturers aware of the increasing advantages of digitizing their production processes. Not only can it improve the quality of the products themselves, it can also significantly reduce downtimes and optimize production overall. At the heart of the matter is the collection and storage of measurement data during processing. As a producer of measurement technology for...

Messer Cutting Systems uses Ophir BeamWatch for non-contact measurement of the laser beam

Precise cuts, sophisticated component geometries, limited material melt – the advantages of laser cutting are numerous. And due to the steady increases in laser power, these advantages can now benefit a range of new applications: fusion cutting is more attractive for structural steel, and thinner materials can be cut significantly faster and more efficiently than ever. These advancements are...

American author, engineer, entrepreneur, and consultant in performance improvement H. James Harrington has been credited as saying, “Measurement is the first step that leads to control and eventually to improvement. If you can't measure something, you can't understand it. If you can't understand it, you can't control it. If you can't control it, you can't improve it.”

Even though Harrington was speaking specifically of improving of the quality in a person’s work performance, the same is true for...
