Laser measurement software from Ophir® can now measure laser power from anywhere! – Part 1

We’ve recently talked about 5 great benefits to using Wi-Fi while measuring your laser. It included reasons that had to do with industrial automation environments, avoiding cables and remote laser monitoring.

Now Ophir Sensors can also be monitored remotely over an Ethernet network – the same type of network connection you probably have in your office, allowing connections from distances far in excess of those supported by RS232 or USB.

Product Focus: Using Ophir’S BC20 to Evaluate Scanned Effects in Light Show Applications

Music concerts, along with other entertainment venues such as nightclubs and theme parks, use laser sources to create colorful and vivid lighting effects.

Even with advances in non-coherent lighting, technology has not been able to replicate the unique appearance of laser lighting effects.

The types of lasers used for light show applications typically emit radiant powers in excess of 20W over a range of common wavelengths based on the technology employed in the projection device. Devices emitting such powers place them firmly into Class 4 laser product territory. How do laser officers deal with the challenge and what does Ophir have to offer? Coming up…

Technical Tip: How to select a power and energy meter – part 2

So, as we’ve started discussing the best way to pick a power meter last week, we’ve reached the third piece of data we need – and that is the laser wavelength. Why is it so important? In order to match it to the sensor absorber characteristics.

We need to select a sensor whose wavelength is within the measurement range of the sensor, power rating is equal to or higher than the maximum power we will measure, whose aperture is larger than the laser beam diameter so that it will contain the whole beam, and whose damage threshold is higher than the maximum expected laser power density at the given wavelength. The sensor absorber should be selected so it matches the wavelength for higher absorption.
