Abstract

The low transmittance mechanical chopper simulator relates to the low transmittance measurement and calibration technology of the glucometer. In order to solve the problem that there is no low transmittance simulator for the glucometer in the prior art, the low transmittance mechanical chopper Adjusting the balance adjusting screw and locking screw in the wave simulator can make the low transmittance mechanical chopper simulator horizontally balanced, and the lower cover and front baffle of the chopper protect the fan-shaped chopper rotating at high speed during operation. In use, the high-speed DC motor drives the fan-shaped chopper to divide the light intensity of the light source in the measurement light path to achieve the effect of simulating low transmittance. The angle of the fan-shaped chopper is selected according to the required transmittance. The invention can realize the low transmittance test condition of the polarimeter.

Description

technical field [0001] The invention relates to a low transmittance measurement and calibration technology for an optical polarimeter. Background technique [0002] When evaluating the measurement performance of the low transmittance measurement of the optical polarimeter, it is impossible to carry out reproducible simulation of the low transmittance test conditions for dark color samples and low transmittance samples. The research on the low transmittance simulator of the sugar meter and the research on the low transmittance calibration technology of the polarimeter are still blank. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the prior art cannot perform reproducible simulation of low transmittance test conditions when measuring low transmittance samples, and cannot evaluate the measurement performance of the optical polarimeter under the condition of low transmittance , thus providing a low transmittance mechanica...
