L50(300)A-PF-65

產品型號：L50(300)A-PF-65
產品說明：

The L50(300)A-PF-65 is a thermal power/energy laser measurement sensor for high peak power pulsed lasers. It has a 65mm aperture and can measure from 400mW to 300W intermittently and to 50W continuously. It measures energy from 200mJ to 300J. It has a damage threshold of up to 3J/cm² for ns pulses and covers the spectral range from 0.15 to 20µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Notes: (a) Long pulses (0.5 – 4s) can be used to measure power of high power lasers by measuring the energy of a short exposure. The StarBright, Juno, Juno+ and Centauri meters have a Pulsed Power mode where the user may specify the pulse width and get a reading directly in units of power for this short exposure energy measurement. (b) Above 1.1μm there is an additional calibration uncertainty of up to 2% (c) Calibrated for 0.25 – 2μm, 10.6μm (d) For 10-50Hz, derate as follows: Wavelength Derate to value 1064nm Not derated 532nm Not derated 355nm 70% of stated value 266nm 15% of stated value 193nm 10% of stated value (e) Damage threshold 1.5J/cm2 for wavelengths <500nm
