AI Technical Summary

Technical Problem

Most of the existing haze transmittance instruments have large sizes and a single measurement diameter, which cannot adapt to samples of different sizes. The lighting spots fail to strictly comply with optical standards, resulting in low measurement accuracy.

Method used

A multi-diameter small haze transmittance meter with interchangeable lens is designed, using integral spheres, photoinductors, swing arm assembly and removable measuring aperture and light source lenses, providing multiple specifications of measuring aperture and light source lenses through Magnetic and thread fixing methods make it easier for users to choose the right configuration and ensure the exact matching of the lighting spot with the measuring aperture.

Benefits of technology

Various requirements for samples of different sizes are achieved, the adaptability and accuracy of measurement is improved, the uniform distribution of light and measurement accuracy are ensured, and the recognition and replacement of lenses are simplified.
