L50(150)A-LP2-35 Low-Medium Power Thermal Sensors for High Power Density and Long Pulse Lasers

L50(150)A-LP2-35

產品型號：L50(150)A-LP2-35
產品說明：

The L50(150)A-LP2-35 is a thermal power/energy laser measurement sensor for high power density and long pulse lasers. It has a 35mm aperture and can measure from 100mW to 50W continuously and to 150W intermittently. It can measure energy from 40mJ to 3000J. The sensor is able to measure high power lasers of up to 4000W by measuring the energy of 0.4 - 4s exposure to the laser. The high damage threshold LP2 absorber covers the spectral range from 0.25 to 2.2µm. The sensor comes with a standard 1.5 meter cable for connecting to a meter or PC interface.

Note: (a) Above 1.1μm there is an additional calibration uncertainty of up to 2%. (b) 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. (c) Powers up to 4000W can be measured. Recommended exposure times and 1/e2 Gaussian beam diameters for very long pulses. Total energy for a series of measurements should not exceed 15kJ. Recommended time between shots 12s.
