Industry-Focused Design
BeamWatch AM is the newest member of Ophir-Spiricon’s family of beam monitoring systems. It has been designed specifically for use in the additive manufacturing industry to provide non-interfering real-time beam measurement at the location of the working plane. Rigorous testing has been performed to ensure it meets the specifications detailed in Table 1 to the right.

...Proper alignment of the MS-1780 is essential for its operation, and this can occasionally seem difficult to achieve. Here is a simple method for making sure the system is properly aligned to get the “first light” conditions that will allow easy fine tuning for experimental results.
In order for the system to work properly the laser beam needs to enter the optical center of the aperture on the horizontal axis of the instrument. In order to be able to fine-adjust the beam it is useful to use steering mirrors to direct...

We started by taking a power reading with the 10kW sensor and a Juno USB Interface to a local PC. This particular sensor had a damaged spot on the thermopile element, so I’m not sure it was giving us an accurate reading. However, here were the recorded power readings:

| The New Year is a time to look back on the past year and contemplate how to do things better. It’s a time to make New Year’s resolutions in an effort to be a better person and do things better. One of the most common and popular New Year’s resolutions is the renewed commitment to losing weight. As many of us are all too familiar with, that means eating better and getting... |

Nowadays, it is quite common to weld with a laser. But some welding applications still require expert skills and customized solutions.
| A customer of ours in the shipyard market owns a powerful 12KW fiber laser. Most of the time, they weld small metals pieces. But for a new application, it required a new process. Welding Large... |

High-power industrial lasers are valuable tools in material processing. Maintaining them at peak performance and optimizing the processes for which they are used will maximize throughput and minimize downtime. Periodic measurement and longterm monitoring of key laser variables, including laser output power, focused spot size, and focus spot temporal location provide the data you need to increase accuracy and optimize your process.
...The need to profile lasers with powers in the 10mW to 1W range are becoming more common. Many of these lasers are in the visible spectrum, allowing them to be measured with CCD and CMOS camera systems. As with any laser that is being measured with a camera array, the beam needs to be attenuated, but there are some cautions to be observed. These beams are not so powerful that they will damage or destroy typical absorptive filters. In fact, it is possible to stack up a sufficient optical density to reduce the power of a 1W laser to the nW...

When a laser malfunctions and diagnostics begin, why is test equipment the first to be questioned for its accuracy when it was the laser that failed first ?
Recently, I had a customer with a 3D system designed to produce 25mW. However as tested on our 30A thermal sensor, it measured 75mW’s! The customer called to complain that our sensor was not working. The sensor was calibrated, did not show any damage to the disc...
The NS v2 software is the same for both Standard and Professional, no need to download/install a different version. To perform the upgrade you must purchase the license for the NS v2 Professional. With the included license key you can click on the blue scanhead image in the left corner and select About from the dropdown, where you can then upgrade the scanhead from the Upgrade License box (see below).

Simple NanoScan/BeamScan Measurements of
Laser Diode Beams Produces Astigmatism Data
Astigmatism measurements of laser diodes, optical elements, and/or other sources can be made quickly and easily using a NanoScan/BeamScan. For example, by simply focusing the beam from a laser diode onto the profiler and measuring the distance between primary and secondary foci, an indication of source astigmatism is readily obtained. However, since this distance is on the order of 10 microns (μm), longitudinal magnification can be...
水銀、重水素、キセノン、クオーツハロゲンランプなどの従来のブロードバンド光源が、今は多くの工業用LEDに置き換わっています。
従来からブロードバンド光の測定はラジオメーターやフォトメーターで行われていました。校正されたフォトダイオードセンサでのLEDパワー測定と放射照度測定については詳細をご参照ください。
パイロエレクトリックセンサを初めてご使用になる時に、センサのダメージスレッルドを予めテストするためのテストプレートが商品に付属しています。ご購入頂いたパイロエレクトリックセンサと同じコーティングが施されています。ご不明点は弊社まで info@ophirjapan.co.jp までご遠慮なくお問合せください。
