OPTICALPOWERMONITORING UV POWER METERC8026/H8025 SERIES For absolute optical power measurement Left: Control Unit C8026 Right: Sensor Head H8025 Series (sold separately) OVERVIEW FEATURES The Hamamatsu UV industrial power meter is designed to measure absolute optical power in the UV to Va-
cuum UV region, in real time mode (mW/cm ● Stable performance at deep UV since no optical filters are used 2 ) or in-tegration mode (J/cm 2 ). The sensor head employs a UV sensor (UV phototube) calibrated based on the NIST standard, allowing UV measurement with a high degree of accuracy and stability over extended periods of use.
This UV power meter is ideal for monitoring and controlling the absolute quantity of UV light in vari-
ous applications such as cleaning, sterilization, cur-
ing and semiconductor process which utilize excimer lamps or low-pressure mercury lamps. Specific UV light can be directly detected without any optical filter. ● Wide light incident angle Acceptable light incident angle is close to cos θ , even without using diffusers. ● Absolute optical power monitoring (mW/cm 2 ) Sensitivity-calibrated data at each wavelength (126 nm, 146 nm, 172 nm, 222 nm, 185 nm, 254 nm) is supplied with the power meter. We also append a Certificate of Calibration. ● Exchangeable sensor heads Six major UV line spectra (126 nm, 146 nm, 172 nm, 222nm, 185 nm, 254 nm) can be monitored by simply exchanging the sensor heads. ● Thin, flat sensor head: 18 mm thickness Allows the sensor head to be used closer to a light source. ● External control The main unit has RS-232C interface for external control.
