Features


  • Low Power Thermopile: Combines the low noise level characteristic of photodetectors with the broad bandwidth and high power capacity of thermal devices.

  • Minimal Thermal Drift: Exhibits exceptionally low thermal drift at only 6 µW/°C with the IR filter, ensuring stable performance across a range of temperatures.

  • High Sensitivity: Provides high sensitivity of 200 mV/W without the IR filter, making it highly responsive to low power laser emissions.

  • Designed for Ultrashort Pulses: The VP (volume absorber) version is specifically engineered for low power lasers emitting ultrashort pulses in the picosecond (ps) and femtosecond (fs) ranges.

  • IR Filter: The XLPF12 model includes an IR filter to eliminate unwanted infrared interference, enhancing measurement accuracy.

  • Isolation Tube: Incorporates an isolation tube to negate the effects of air turbulence on power measurements, ensuring consistent results.

  • Compatibility: Fully compatible with various stands, displays, and PC interfaces, offering flexibility in setup and integration.


These features make the XLPF12-3S-H2-D0 detector a versatile and reliable choice for precise laser power measurement across a range of applications, particularly those involving low power lasers and ultrashort pulse durations.
