    The spectral response, cathode sensitivity, gain, resolution and signal-to-noise ratio of the super second-generation and the third-generation image intensifier were measured at the short wave cut-off of 550 nm, 625 nm and 675 nm for A luminant. Under 10-1 lx illumination, the resolution of the third-generation image intensifier does not decrease after undertaking 675 nm short wave cut-off for A luminant, while the resolution of super second-generation image intensifier drops to 94% of the initial value; however, under 10-4 lx illumination, the resolution of the third-generation image intensifier decreases to 90% of the initial value after undertaking 675 nm short wave cut-off for the A luminant, while that of the super second-generation image intensifier decreases to 85%of the initial value. In addition, the resolution decreases with the decrease of illumination. For the super second-generation and third-generation image intensifiers, although the parameters are the same under the illumination of A luminant, but when used in different short wave cut-off wavelengths, the performance of the third-generation image intensifier is better. Although the decline proportion of parameters for super second-generation image intensifier is higher than that of third-generation image intensifier under different short wave cut-off wavelengths, the difference is not obvious, so the performance difference during use is not obvious.
