Their compact structural design and stable signal transmission capability make them indispensable core detection components in industrial automated production lines.

Core Product Highlights and Technical Advantages

High-Precision Measurement Performance with Accurate and Reliable Data

The STXF series products excel in measurement accuracy, with electrical accuracy up to ±0.25% and power measurement accuracy as low as ±3%, while energy measurement accuracy remains stable and controllable. The sensors adopt a wide-spectrum design: most models cover a spectral response range of 0.19~11μm, and some homogenized light models (suffixed with J) cover 0.28~1.1μm, perfectly adapting to the measurement needs of multi-band lasers such as infrared and ultraviolet. Linearity is strictly controlled within ±1%, ensuring numerical accuracy across the entire measurement range and providing a solid guarantee for scenarios with high data precision requirements such as precision machining and scientific research experiments.

Full Power Range Coverage with Diversified Model Adaptability

To meet laser applications of different power levels, the STXF series has built a complete product matrix ranging from milliwatt to kilowatt class, covering multi-specification power segment sensors:

• Low-power segment (2mW-12W): Includes the STXF-TP10 series and STXF-USB/RS232-2~12 series, suitable for the accurate measurement of small laser equipment and low-power laser sources in laboratories.

• Medium-power segment (10mW-600W): The STXF-TP50~TP600 series sensors adopt natural cooling or conduction cooling methods, adapting to mainstream application scenarios such as industrial laser processing and medical laser equipment.

• High-power segment (0.5W-3500W): Covers the STXF-TP1000~TP3000 series and water-cooled models (suffixed with W). Among them, the water-cooled sensors can withstand continuous laser power up to 3500W, ensuring stable operation under high-power working conditions with the help of an efficient water cooling system, and are suitable for industrial heavy-duty scenarios such as large laser cutting and welding equipment.

User-Centered Design Concept with Convenient and Efficient Operation

Display-type products are equipped with a 3.5-inch true-color LCD screen, supporting three display modes: numerical, bar chart, and line graph. With a 480*320 high-definition resolution and multi-level backlight adjustment, they ensure clear data reading under different lighting conditions. The Stellar V2 display unit has a built-in 3600mAh high-capacity lithium battery, supporting 24 hours of continuous operation after 12 hours of charging, fully meeting the needs of long-term on-site measurement. It also supports connection to PC-side monitoring software via a USB-B interface to realize data storage, analysis, and export, with a maximum capacity of 10,000 data points or 1667 hours of continuous measurement records.

All products in the series support user self-calibration, greatly simplifying the calibration process and reducing long-term maintenance costs. Some models are equipped with a self-stabilizing zero circuit design, eliminating the need for manual zero calibration, further improving operational efficiency, and effectively reducing the interference of environmental factors on measurement results.

Robust and Durable Structure with Optimized Heat Dissipation Design

As core detection components, the sensors adopt an optimized and upgraded heat dissipation design: low and medium-power models combine natural cooling and conduction cooling methods, featuring high heat dissipation efficiency and easy maintenance; high-power models are equipped with a professional water cooling system, and some water-cooled models have a minimum water flow requirement of only 1.0L/min, significantly reducing supporting costs while ensuring heat dissipation efficiency. The sensor housing is made of wear-resistant and corrosion-resistant materials, with probe apertures available in multiple specifications such as 19mm, 25mm, and 50mm, which can match the laser measurement needs of different spot sizes. The cable length is uniformly 2m, balancing installation flexibility and signal transmission stability.

Model Naming Rules and Selection Guide

The STXF series products adopt a standardized model naming system, facilitating users to quickly identify core parameters:

• Display-type model format: STXF-TPX-YY-Z, where "X" represents the power range (e.g., 10=10W, 500=500W), "YY" represents the probe aperture (e.g., 19=19mm, 25=25mm), and "Z" represents special configurations (J=Homogenized Light, W=Water-Cooled).

• OEM-type model format: STXF-USB/RS232-X-YY-Z, with core parameter identifiers consistent with display-type models, and the prefix clearly indicating the communication interface type.

Three core factors should be focused on during selection: first, the laser power range and measurement mode (continuous/pulsed); second, the laser wavelength and spot size (which need to match the sensor's spectral range and probe aperture); third, the specific application scenario (display-type is preferred for standalone use, and OEM-type is suitable for system integration scenarios). For example, the STXF-USB-200-25 model can be selected for online monitoring of industrial laser cutting machines, and the Stellar V2 display unit can be paired with the STXF-TP50-19J sensor for pulsed laser experiments in laboratories to achieve accurate measurement.
