The XLP12-3S-VP-D0 is a precision thermopile laser power detector designed by Gentec-EO, offering reliable measurement capabilities for laser power up to 3 watts. This advanced device is engineered to provide the noise level of a photo detector while maintaining the large bandwidth and high power capacity typical of thermal devices. Its robust design ensures minimal thermal drift, with a drift rate of only 6 µW/°C when equipped with the IR filter, making it an ideal choice for precise and stable measurements.

One of the standout features of this thermal detector is its high sensitivity, rated at 200 mV/W without the IR filter. This makes it particularly suitable for low power lasers with ultrashort pulses, such as picosecond and femtosecond lasers, thanks to its VP (volume absorber) version. The inclusion of an IR filter in the XLPF12 model effectively removes unwanted infrared interference, ensuring accurate readings.

To further enhance measurement accuracy, the detector is equipped with an isolation tube that eliminates power fluctuations caused by air turbulence. This thoughtful design feature ensures that this thermal power detector delivers consistent and reliable performance in various environments. The device is compatible with a range of stands, displays, and PC interfaces, including the MAESTRO, TUNER, UNO, and various P-LINK and S-LINK models, providing flexibility and ease of integration into existing systems.

Physically, the XLP12-3S-VP-D0 thermal detector is compact and lightweight, with dimensions of 73H x 73W x 20D mm and a weight of just 0.32 kg. Its 12 mm aperture diameter and VP absorber make it a versatile tool for a wide range of laser power measurement applications. With its combination of high sensitivity, minimal thermal drift, and robust design, the XLP12-3S-VP-D0 stands out as a premier choice for professionals seeking precision and reliability in laser power measurement.
