LED’s are used today in many applications with the most prominent being the lighting of our homes, streets and businesses. Despite their clear advantages, measurement techniques of the power, flux and spectrum of LEDs is not very different from that of traditional types of lamps.

The 3A family of laser power sensors is one of our most popular – and for good reason.
You might already know the basic points:
It’s very sensitive (down to 10 μW), yet comes with all the benefits of a thermal-based sensor: high damage threshold and spectrally flat across a very wide spectral range.

Lasers are famous for their focusability. (As in: “laser-focus.”)
That’s why many laser power sensors have 30, 20, or even just 10 mm apertures. This is usually more than enough space for a laser beam.
But what about large lasers like diode stacks or non-laser light sources? How can a small sensor measure a large laser beam?

Broadband spectral sources, such as arc lamps or gas-discharge lamps are still used in many lighting applications due to their high efficiency and other unique characteristics.
Lasers are measured with laser power meters. But how can you measure a broadband spectral light source?

Pyroelectric sensors are the tool of choice for measuring energy of repetitively pulsed laser beams.
They measure energy, and they’re fast.
They are not, however, indestructible.

Disclaimer: Don’t do anything stupid.
What I’m about to tell you is a trick that should NOT be used lightly.
However, in many cases Ophir sensors can be used for far higher powers than in the spec, as long as it’s only for a short time exposure.

We’re all agreed that pyro sensors fill in an important gap in laser power and energy measurement.
Now that you have your pyroelectric sensor, here are some tips to get the most accurate measurement possible.

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%.
