The Most Versatile Sensors for Very Low Power Lasers
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.

How to Measure Broadband Spectral Sources
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?

How to Measure Low Power Lasers (Picowatts to Watts)
There are a few different ways to measures laser power, but the most common is the photodiode. Photodiodes translate light energy into electricity (current), which can be measured by a current sensor.
Ophir uses a few types of photodiodes in its PD300 series.
