It is suggested that a photoexposure meter "Photon-1" (TU-4-72) be used for the determination of exposure in microphotography. The photoelement of the apparatus is overlaid on the eyepiece of the photo device. The regulator of the apparatus is set in a position corresponding to the film sensitivity. The exposure meter shows exposure time in seconds.
建议使用“光子 -1”型（TU - 4 - 72）曝光计来测定显微摄影中的曝光量。该仪器的光电元件覆盖在照相设备的目镜上。将仪器的调节器设置在与胶片感光度相对应的位置。曝光计以秒为单位显示曝光时间。
