The maximum pulse repetition rate depends on the internal capacitance of the detector as well as the load resistor. All detectors can be directly connected using the BNC sockets to the 1MOhm-Input of an oscilloscope. A small load resistor can be used to obtain the highest pulse repetition rate. Repetition rates of up to 100 Hz are then possible.

Each head is automatically recognized and its individual calibration data are uploaded to the system. In addition, the user may load up to 5 separate filter curves. Thus, the dynamic range and functionality of the unit can be expanded while ensuring proper calibration.

This pyroelectric detector head STPEM45KUSB respectively STPEM45USB is a combination of a robust pyroelectric sensor with a read out electronic with USB-port. It can be connected to an oscilloscope using the BNC-connector or to a PC using the USB port. In USB mode the BNC connector is an external trigger input.

This read out unit is designed to measure the output power of different lasers in combination with a thermopile detector. The maximum power is limited by the used power head. By using this read out unit it is possible to reduce the time constant of the whole measurement system to 1 second. Normally, the time constant of a power head is in the region of 15 to 25 seconds.

Designed to measure power levels from 1 - 250W, the power meter measures output power from the ultraviolet to the far infrared. This makes it the perfect tool for checking the performance of your excimer, argon, diode, YAG, and CO2 lasers, to name just a few.

The STPEM12E is a 12 mm diam. Sensor, combined with a low noise preamplifier. So it is possible to measure smallest laser energies. To use the whole dynamic range of the built in sensor element, the detector is equipped with a switch for changing the amplification. We offer this detector with two different coatings. For use at different wavelengths we recommend our reliable broadband black coating, whereas for high repetition rates and the UV range we recommend the metallic coating. Higher sensitivities and repetition rates are possible on request.

Automatic data hold and auto ranging make the power meter easy to use. Simply insert the sensor into the laser beam and hold in place for a few seconds. The easy-to-read LCD screen will then display an accurate measurement of average laser power. To take another reading, simply push the reset button, and the power meter is ready to go.

These detectors are a combination of our standard sensors with a flat housing. In these smaller housings the BNC connector is replaced by a SMA connector. The detectors are coated with a black absorption layer which possesses an almost constant absorption in the wavelength range from 185 nm to 25μm. Particularly beneficial is the comparatively high sensitivity of the detectors which without an additional amplifier and due to the insensitivity to interferences permits laser pulse measurements in the μJ range.

4. DATA LOGGING - Save your data to the internal memory and then transfer it to your PC over the USB connection.

The maximum pulse repetition rate depends on the internal capacitance of the detector as well as the load resistor. All detectors can be directly connected using the BNC connector to the 1 MOhm-Input of an oscilloscope. A small load resistor can be used to obtain the highest pulse repetition rate. Repetition rates of up to 100 Hz are then possible. Load resistors of 100 KOhm are part of the deliverable assortment. The corresponding sensitivity of the sensors is also specified.

The spectral behavior is flat in the VIS and NIR but for longer wavelengths the absorption properties have to be taken into account. Main application is the use at one wavelength. The metallic coating of the two UV types is more stable in the ultraviolet region than the organic black coating.
