Deviation from calibration -3% at 30,000 inch/s scan rate on sensor. Damage Threshold W/cm2 10 10 50 Max Pulse Energy ìJ 1 1 NA Noise Level pW 2 ±1mLux 5ìW Response Time with Meter s 0.2 0.2 Two modes of operation: Hold: holds highest reading for 5s then updates. No Hold: updates reading 3 times per second. Beam Position Dependence ±2% for broadband light sources NA – source overfills detector ±2% Background Subtraction NA NA Background is automatically subtracted from both scanned and static beams.
