LBTEK USB laser power meters are available in two types: thermopile-based and photodiode-based. The thermopile power meter uses a thermopile sensor made of series-connected thermocouples, making it suitable for high-power measurements, while the photodiode power meter uses a multi-channel photodiode sensor, ideal for low-power measurements.
The USB laser power meter features a wide wavelength measurement range, supporting operation from 190 nm to 25 μm. It also covers a broad power measurement range, capable of measuring continuous laser power from 1 nW to 200 W. In addition, it offers multiple choices for detector area, with maximum incident beam diameters ranging from 9 mm to 25 mm. Users can select the product that best fits their requirements but must ensure that the maximum power density of the chosen sensor is not exceeded during operation.
The LBTEK USB photodiode laser power meter (with attenuator) uses a multi-channel photodiode sensor based on the photoelectric effect. It features a fast response time but is prone to current saturation, making it suitable for low-power continuous laser measurements. Multiple power ranges are available, allowing the detection of continuous laser power from 1 nW to 1 W. When connected to a PC via the provided USB data cable, the software displays real-time measurement data, statistical data, and stability values. It also shows measurement curves with up to 40,000 data points and supports basic operations such as zooming, saving, and opening recorded data. The LBTEK USB photodiode laser power meter (with attenuator) is available with two effective detector area options: 9.5 mm and 10 mm.
