When measuring very high power laser beams, even the few percent of the beam normally back-scattered from the sensor can be a problem. Ophir now offers Scatter Shields as accessories for our high power laser sensors; these can be mounted on the front flange of the sensors to reduce the backscatter by about 70%.

Not everyone knows this, but almost all Ophir power and energy sensors can be used with four standard fiber adapters:
SMA
FC
ST
SC
Of course, any fiber can be measured by an Ophir sensor by taking a free-space measurement – placing the fiber tip a few mm or cm from the sensor and letting the laser beam continue to the sensor.
However, in many cases it is convenient to use a fiber adapter to connect to a measuring device.
If that’s the case, here’s what you’ll want to do.

With high power lasers, there’s always a safety concern for equipment and people nearby.
(Of course, I’m not qualified to give a detailed analysis of what needs to be taken into account for laser safety. For that, you should consult a laser safety officer.)
I want to specifically ask whether there’s an issue of laser light reflecting off power measuring equipment.

Harsh.
Extreme.
Noisy.
These are a few words used to describe an industrial environment.
What about your laser sensor? Will it survive this?
