摘要 |
FIELD: the invention refers to optical measuring technique. ^ SUBSTANCE: the portable device for measuring of power of alternate-reflecting light designed for control of quality of light-reflecting articles has a source of light in a light-proof body for lighting of light-returning sample, an arrangement for stationing the sample under a given angle of lighting, a photo receiver for receiving alternate-reflective radiation and a half-transmitting mirror providing coordination of spatially dispersed channels of radiation and photo-receiving with the channel of lighting-reflective sample. The input opening of the photo receiver is fulfilled on a removable light-tight screen and its zones of light transmission are displaced from the axle of the photo receiver on a distance proportional to the required angle of divergence. At that a collecting lens is located between the screen and a light-sensitive element of the photo receiver. ^ EFFECT: increases accuracy of measuring. ^ 3 cl, 6 dwg |
