High Power Thermal Sensors

Product catalog summary
Overview: This document provides technical specifications for two high power thermal sensors, models L250W and L300W-LP1-50, designed for general purpose and high power density applications respectively.
Specifications:
  • Model L250W: Suitable for general purpose use with a broadband absorber type. It operates within a spectral range of 0.19 - 20 µm and has a power range of 1W - 250W. The maximum average power density is 10 kW/cm² at 250W.
  • Model L300W-LP1-50: Designed for high power densities and long pulses with an LP1 absorber type. It covers a spectral range of 0.35-2.2 µm and 10.6 µm, with a power range of 1W - 300W. The maximum average power density is 23 kW/cm² at 300W.
Energy Mode:
  • L250W: Energy range from 120mJ to 200J with energy scales of 200J / 30J / 3J.
  • L300W-LP1-50: Energy range from 200mJ to 300J with energy scales of 300J / 30J / 3J.
Cooling and Accessories:
  • Both models require water cooling with a minimum flow rate of 1 liter/min. The water temperature should be between 18-30°C with a rate of change less than 1°C/min.
  • Accessories for high power sensors are available on pages 59, 60, and 61.
Additional Notes:
  • LP1 sensors have a calibrated spectral curve for accuracy across their spectral range. When used with Nova, Orion, and LaserStar meters, accuracy is ±3% for 1.06µm and 10.6µm, and ±6% for other wavelengths in the 600-1100nm range.

LP1 sensors have relatively large spectral variation in absorption and have a calibrated spectral curve at all wavelengths in their spectral range to the above specified accuracy. Nova, Orion and LaserStar meters do not support this feature and when used with those meters, accuracy will be ±3% for 1.06µm and 10.6µm, and ±6% for other wavelengths in the spectral range 600-1100nm. Water temperature range 18-30°C. Water temperature rate of change <1°C/min. Water Connector R1/4-20 BSW x6 deep Water Connector for 1/4" Plastic Hose For latest updates pleas
