L40(250)A-BB-50

Product catalog summary
Specifications and Features:
  • The document details specifications for medium power large aperture thermal sensors with apertures of 50mm, suitable for continuous, long pulse, and Excimer lasers.
  • Models include L40(250)A-BB-50, L40(250)A-LP2-50, L40(200)A-EX-50, and L50(250)A-BB-50.
  • These sensors have a thin profile and can handle CW to 50W, intermittent to 250W, and pulse energies up to 10,000 Joules.
Recommended Usage:
  • Recommended exposure times and 1/e² Gaussian beam diameters are provided for very long pulses, with a total energy limit of 20kJ for a series of measurements.
  • Cooling down time before another 20kJ series is less than 10 minutes, with a recommended time between shots of 12 seconds.
Performance Parameters:
  • Power range is from 300mW to 250W, with maximum intermittent power specifications detailed for each model.
  • Energy range varies by model, with scales provided for different energy levels.
  • Maximum average power density and response time with meter are specified, along with power accuracy and linearity with power.
Additional Features:
  • Cooling is achieved through convection or ballistic methods, and fiber adapters are available for certain models.
  • Compliance with CE and China RoHS standards is noted.
Notes:
  • Additional calibration uncertainty is mentioned for wavelengths above 1.1µm, with specific details for long pulse measurements.
