Scope

GB/T 45618-2025 is the English-translated version of 日盲紫外像增强器技术要求.

GB/T 45618-2025 is the Chinese national standard covering the tube that turns an ultraviolet image into one the eye can see — the photocathode response in the 200 to 280 nanometre band that the ozone layer strips out of sunlight, which is what lets a weak source be seen against a daylit background, the fibre optic faceplate and the phosphor screen, the high voltage supply, and the low temperature, damp heat, vibration, shock and salt spray tests. First edition, under the Ministry of Industry and Information Technology. In force from 1 November 2025. Issued on 25 April 2025, it has been in force since 1 November 2025.

3 Terms and definitions

The terms and definitions defined in GB/T 4597-2012 and the following apply to this document.

3.1 The wavelength of light forms a spectral region

The.200nm~280nm spectrum light in the solar radiation is strongly absorbed by the atmospheric ozone layer, making it almost invisible in the solar background near the Earth.

3.2 Image intensifier

It can convert and enhance the radiation image of solar-blind ultraviolet photons projected onto the photocathode and display it on the fluorescent screen to adapt to the human eye.

Observe the visible light image of the vacuum optoelectronic imaging device.

3.3 High-voltage power supply

The DC low voltage is converted into multiple high voltage outputs through a transformer to provide working voltage power to each pole of the solar-blind ultraviolet image intensifier tube.
