The UV image intensifier is one kind of electric vacuum imaging device based on principle of photoelectronic imaging.
To achieve solar-blind detection, its spectral response characteristic is extremely desirable. A broad spectrum response
measurement system is developed. This instrument uses EQ-99 laser-driven light source to get broad spectrum in the
range of 200 nm to 1700 nm. A special preamplifier as well as a test software is work out. The spectral response of the
image intensifier can be tested in the range of 200~1700 nm. Using this spectrum response measuring instrument, the
UV image intensifiers are tested. The spectral response at the spectral range of 200 nm to 600 nm are obtained. Because
of the quantum efficiency of Te-Cs photocathode used in image intens ifier above 280nm wavelength still exists,
especially at 280 nm to 320nm.Therefore, high-performance UV filters is required for solar blind UV detection. Based on
two sets of UV filters, the influence of solar radiation on solar blind detection is calculated and analyzed.
