Picture this:
You’re working on a complicated laser setup, with various beam splitters, attenuation, lenses and mirrors. You spend weeks optimizing the design, and months waiting for all the parts to arrive.
Now everything is here and you set it up to the millimeter.
And then the big moment. Where’s the laser?

You need a sensor (thermal, photodiode, pyroelectric) to measure laser power, but how do you take that raw measurement signal and move it to a display. You have a few options, and in this post will explore the benefits of Juno – as well as the cases when other options would be preferred.

You might think – as I used do – that offset is pretty simple.
Before measuring your laser, see if the meter displays a value.
If not, great. If it does, that’s unwanted, so press “Offset.”
However, the truth is there are several different kinds of offset and it’s important to understand a little bit about how thermal sensors work in order to know when to hit that offset button and when to resist.

Updated March 2016: I made a few changes to this post now that the new low power RM9-PD is available.
There are many different types of lasers.[citation needed]
UV, visible, infrared, Terahertz.
Nanowatts, milliwatts, kilowatts.
Lasers for industry, laser for medicine, lasers for telecommunication.

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?
