STXF Series Laser Power Meters

The STXF series laser measurement products include laser power meters and laser energy meters. Some models support both power and energy measurement, and are also called laser power and energy meters. These products measure laser power and energy values, providing data support for the magnitude and stability of laser parameters.

Laser power meters are classified into two types:

  • Display type: Equipped with an LCD display and built-in battery. It can display readings in real time without relying on a computer.

  • OEM type: Integrated into laser systems, powered by the equipment itself (no built-in battery), and transmits data to the computer via communication interfaces such as USB and serial ports.

Our power meters consist of a sensor and a processing unit. For the display types, these two units correspond to a sensor and display unit; for OEM types, they correspond to a sensor and data processing unit.

The power sensor receives high-energy laser beams, making it prone to contamination and damage. Regular calibration is required if high measurement accuracy is needed. Our power meters support user self-calibration, thereby simplifying the calibration process and providing operation flexibility.

STY Series Hand-held CO2 Laser Power Meter

The hand-held laser power meter STY-HLP-200B is a CO2 laser power meter. Its measurement range is maximum 200W with the resolution 0.1W. A button battery is used as the power supply and thus it is very easy and portable used in production, QC and laboratory. A mount hole is alternatively used to be fixed instead of hand-held for better stability.

Remarks:

  • All above sensors can be used as sensors to measure laser power, also can be used as beam dumps. However, if you just need a beam dump and not measure laser power, please just buy the beam dump at lower prices. The part number of the beam dump is ended with BD at the corresponding sensor. For example, the sensor is STCH-W5000-CA-55 and the corresponding beam dump is STCH-W5000-CA-55-BD.

  • A complete laser power meter may be a sensor + a display unit, or a sensor + a USB output (the USB output can be connected to PC). All the display unit can be connected to PC.

  • All the accessories such as sensor supports are optional.

  • We can custom-design and -make the sensors and powermeters according to your specific requirements and please contact us for more discussions.
