Shutter Slit Systems – For Controlling Light

Most photonic industrial applications and laboratory experiments use piezo products such as ring actuators, tip-tilt stages and shutter/slit mechanics for precise nanometer light guiding and shaping. The 4-product PZS series of shutter/slit systems from piezosystem jena offers a variety of benefits including multiple opening sizes, multiple slit-edge materials, and an optional strain gauge measurement system. Datasheets and part drawings are found here:

How is laser power output measured:

One specification that is always in the description of lasers is its power level, but have you ever wondered how these laser manufacturers measure laser power?

There are a lot of different ways to measure this parameter. Three technologies are often found in industrial power detectors: photodetectors, thermopiles and water calorimeters.

Let me present how each technology works as well as their advantages and disadvantages.

Laser power measurement with photodetectors

Photodetectors are mainly used for power in the picowatt to milliwatt range. They are made from semiconductors with a p-n junction that converts photons coming from a light source into an electric current. The more photons available, higher is the current.

The wavelength range of a photodetector depends on the semiconductor used. For example, Germanium photodetectors are often used with the 1550 nm wavelength that is used in telecommunication since it is compatible with this wavelength.

Photodetectors have a short response time which makes them the preferred choice in applications where power variations need to be quickly monitored. Even if photodetectors are made for lower powers, it is possible to add attenuation, a pick-off or an integrating sphere in order to use photodetectors at higher power.

One of the downsides of these detectors is their absorption that depends on the wavelength. It is important to select the correct wavelength; otherwise, the measurement will be way off. A good example of photodetectors is our PH series.

How Do You Test Photovoltaic Solar Cells?

We’ve covered a lot of material as far as how solar cells work, and what their operation depends on. While it can seem quite daunting to try and dream up a test that captures all of the various factors we’ve discussed, the key information we need can be found in a few graphs/parameters:

1. Responsivity
2. External Quantum Efficiency (EQE)
3. IV response
4. Efficiency

The first three graphs are what we need to calculate the overall solar cell efficiency, and we’ve already introduced all of the quantities above. Essentially, what we’re after is how the solar cell responds to different wavelengths (which is given by the responsivity and EQE), as well as how it responds under different electrical conditions (which is given by the IV response). So how do we conduct tests to measure each of these things?

Because the photovoltaic industry is so large and active, there are actually standard test methods for measuring parameters of photovoltaic devices. We won’t go into great detail as far as what the tests involve, but it’s worth outlining the key elements of the tests, as well as how they’re typically done in practice.

Synchronized multichannel lock-in measurement system

The MCL1-540 is a compact multichannel lock-in amplifier measurement system which can make complex AC and DC measurements on up to ten different analog signals.

In addition it can generate excitation signals to drive the experiment, as well as measure the current delivered by these signals.

It is therefore ideally suited to making direct impedance measurements on samples such as superconductors or in material analysis, as well as for use in optical, calorimetric, AC susceptibility, and many other experiments.
