Frequently Asked Questions

Energy sensors are high accuracy devices designed to measure different levels of laser energy.

There are two main types of energy sensors: Pyroelectric and Photodiode. Pyroelectric sensors operate by measuring repetitive pulse energies and average power, while photodiode sensors measure very low energy pulse lasers. Most energy sensors connect to a compatible computer or tablet PC using designated software.

Energy sensor devices can measure as little as very few nanojoules to numerous joules per pulse. Different units are able to measure different maximum/minimum levels of energy.

Common applications for energy sensors include laser energy measurements in any spectral range, laser optics, spectroscopy (measuring and interpreting the electromagnetic spectrum), and basic metrology (scientific study of measurement).

Important features to consider when selecting an Energy Sensor are aperture, noise level, power capability/average power, max repetition rate, max measurable energy, absorber type, and spectral range.

Energy sensor units are built for easy operation, compactness, and durability. They operate at extremely high repetition rates and exhibit high damage thresholds (limit to which an optic is damaged by a laser). Energy sensors also have high insensitivity to electromagnetic interference, an important element when operating in lab environments. Most devices are programmed with calibration sensitivity and spectral correction factors for varying wavelengths.

There are 64 different Energy Sensors from suppliers and manufacturers listed in this category. In just a few clicks you can compare different Energy Sensors with each other and get an accurate quote based on your needs and specifications. Please note that the prices of Energy Sensors vary significantly for different products based on various factors including technical parameters, features, brand name, etc. Please contact suppliers directly to inquire about the details and accurate pricing information for any product model. Simply navigate to the product page of interest and use the orange button to directly reach out to the respective supplier with one click.

Did You know?

Laser energy meters, also known as energy sensors, are essential devices used in scientific and industrial applications to measure the output of lasers in a broad spectral range. These high-accuracy devices are designed to measure the optical energy output of lasers. Energy sensors, including pyroelectric and photodiode sensors, are commonly used for measuring the output of lasers in spectroscopy applications. Pyroelectric sensors measure repetitive pulse energies and average power, while photodiode sensors measure very low-energy pulse lasers. Laser energy meters play a critical role in general metrology, the scientific study of measurements and units, and it's important to choose the right sensor for your specific application based on factors such as power range, wavelength, and measurement requirements. FindLight offers a wide range of energy and power sensors, including pyroelectric detectors, to help you find the perfect sensor for your needs.
