The XLPF12-3S-H2-D0 Thermopile Laser Power Detector by Gentec-EO is a precision instrument designed for accurate laser power measurement up to 3 watts. This advanced device is engineered to deliver the noise level of a photo detector while maintaining the large bandwidth and high power capacity of a thermal device, making it an ideal choice for professionals who require reliable and precise laser power measurements.

One of the standout features of this thermal detector is its minimal thermal drift, which is only 6 µW/°C when used with the IR filter. This ensures consistent performance and accuracy even in varying temperature conditions. The detector also boasts high sensitivity, with a rating of 200 mV/W without the IR filter, allowing it to detect even the slightest changes in laser power.

This model is particularly suited for low power lasers with ultrashort pulses, thanks to its VP (volume absorber) version. The inclusion of an IR filter in the XLPF12 model effectively removes unwanted IR interference, enhancing the accuracy of measurements. Additionally, the isolation tube feature eliminates power fluctuations caused by air turbulence, ensuring stable and reliable readings.

Physically, the device is compact and lightweight, with dimensions of 73H x 73W x 28D mm (80D mm with tube) and a weight of just 0.32 kg. It features a 12 mm aperture diameter and an H2 absorber, making it versatile and easy to integrate into various setups. The device is compatible with a range of displays and PC interfaces, including MAESTRO, TUNER, UNO, and several S-LINK and P-LINK options, providing flexibility in data management and analysis.
