User manual 11XLP12
Low Power Thermopile
Noise level of a photo detector with the large bandwidth and high power capacity of a thermal device
Minimal Thermal Drift
Only 6 µW/°C (with the IR filter)
High Sensitivity
200 mV/W (without the IR filter)
Special Model For Ultrashort Pulses
VP (Volume Absorber) version is perfect for low power lasers with ultrashort pulses (ps and fs)
IR Filter (XLPF12 model)
Removes unwanted IR interference
Isolation Tube
Eliminates power fluctuations created by air turbulence
Smart Interface
Containing all the calibration data
 
 

11XLP12-3S-H2 Extreme Low Power Laser Detector best suitable for low power im both the µW and mW regimes with very low thermal drift. Featuring broadband flat spectral response, minimal thermal drift and a noise equivalent power as low as 0.5 µW the 11XLP12 is ideally suited for measuring any pulsed or CW low power laser.
