Production systems for the luxury food and tobacco industries are complex, achieve very high throughput rates and often run 24/7. In order to ensure the products’ high quality, the Körber Business Area Technologies counts on seamless monitoring of the entire manufacturing process in the plant. This expectation also applies to the laser-based perforation systems that the company integrates into its lines. Based on Körber’s specifications, MKS developed a customized Ophir® OEMsensor to measure the laser power, which can be integrated directly into the equipment. For maintenance tasks, the plant ..read more

In case you’ve missed it, MKS Instruments, Inc has announced Ophir® BeamWatch® Plus, a non-contact beam profiling system for measuring focus shift, focus spot size, and position of high power industrial lasers operating in the VIS and NIR range. Introduced at LASER World of Photonics, BeamWatch Plus is a second-generation system that now measures high power lasers in VIS wavelengths (420 – 635nm), primarily green and blue lasers, in addition to the NIR region (950 – 1100nm). Designed for very high power YAG, fiber, and diode lasers used in industrial material processing applications, Beam ..read more

We’d like to take a moment and share how much grateful we are for the incredible experience at Laser Munich Trade Show! Thank you for visiting our booth and engaging in exciting conversations about cutting-edge laser technology. New innovative solutions Among other things, we had the pleasure to introduce you to our new BeamWatch® Plus – Ophir’s first non-contact beam profiler, which now supports high power VIS and NIR lasers. The system analyzes industrial multi-kilowatt lasers by measuring Rayleigh Scattering. We’ll elaborate more about the BeamWatch® Plus on our next week’s blog post, so st ..read more

Additive manufacturing, commonly known as 3D printing, has transformed the manufacturing industry, enabling the creation of complex and customized objects with unprecedented precision. One critical aspect of additive manufacturing is the monitoring and control of the printing process within the chamber.   While precision and efficiency are paramount, having user-friendly tools is essential for technicians in the field.   We are proud to unveil our simplified laser analysis BeamPeek Software, specifically designed to cater to the needs of technicians operating in additive ma ..read more

Here’s why you want to come and say hi… Use a laser? you wouldn’t want to miss MKS’s booth at Laser World of Photonics. Here’s a taste of featured applications and products you can expect to see there from Ophir: – 3D printing & Additive Manufacturing: BeamPeek beam profiler for AM, Ariel power meter for AM, and BeamWatch AM integrated lase ..read more

What do you enjoy doing outside of work? We have a family that’s larger than most families with six kids, so most of my activities outside of work involve them. We enjoy camping throughout the year, along with just being outside in nature. My two older boys and I ride motorcycles and we like to take as many rides as possible throughout the year. We’re also a musical family. I’ve enjoyed playing musical instruments most of my life, from the trombone in the marching band, bass guitar in jazz band, along with playing hair metal bass guitar in a garage band in high school, to now sitting around t ..read more

Lasers are made of physical matter. Therefore, the natural degradation of their materials can cause variability in performance. Aging optics often cause slow changes in laser behavior and, when left unchecked, these changes can lead to loss of process efficiency. An unclean process environment can quickly change a laser’s behavior through thermal lensing, which is caused by debris collected on laser optics. In this webinar, produced by Photonics Media, John McCauley discusses how these variabilities are managed, what aspects of a laser’s performance should be analyzed, and what tools are avail ..read more

What would live concerts, festivals and TV shows be without breathtaking laser shows and stunning special effects? laserfabrik GmbH is active in this field worldwide and has more than 20 years of experience. One area that has become increasingly important in recent years is stage marking. The aim here is to indicate the positions of actors and technical crew on stage by using laser projections. But the safe usage of the lasers remains the highest priority for the laserfabrik team. The company’s proprietary series of measurements, taken with Ophir sensors, yielded instructive insights on the la ..read more

There is a fair amount of confusion caused by the reporting of dynamic range of beam profilers. The purpose of this blog post is to explain some of the terminology used in the discussion of this parameter by both Ophir- Spiricon and other suppliers of beam profilers. Definition Dynamic Range is the ratio of the largest measurable signal to the smallest measurable signal. The smallest measurable signal is typically defined as that equal to the noise level, or alternatively the “Noise Equivalent Exposure” or that point where the Signal-to-noise ratio (SNR) is 1.   To measure a beam profile ..read more

Are you trying to measure a low-power, slowly pulsing beam (think of a VCSEL beam for example) – and getting frustrated? Measuring low-power, slowly pulsing beams using photodiode sensors can be surprisingly tricky. Learn about the technical challenges you’ll face when trying to measure such beams, and about the Ophir solutions that will help you.
