The "GCMS series" is an angle-variable spectrophotometric color measurement system that can measure colors that change due to differences in observation angles and light incidence angles, as spatial distributions of reflected and transmitted light. The "GCMS-3B" and "GCMS-4B" accurately control the incidence and reception angles, performing spectral distribution measurements at each angle.

This device is a system for monitoring the haze value of film sheets on a production line. By adopting a method that receives and calculates light at 0° (parallel light) and nearby diffuse light without using an integrating sphere, it enables highly stable monitoring. 【Non-contact haze value measurement】 Traditionally, measuring haze values required determining the transmittance of diffuse light using an integrating sphere. However, the integrating sphere device necessitates close contact with the sample, making continuous online measurement impossible. Furthermore, in measurements using an integrating sphere, there is a time lag between the 0° measurement and the diffuse light measurement, which can lead to discrepancies in measurement positions for continuously produced samples, resulting in inaccurate values. Additionally, the integrating sphere requires high reflectivity and uniformity, posing maintenance challenges for long-term stability and reproducibility. Therefore, we developed a unique measurement method through years of experience and data accumulation, effectively resolving these issues. 【Installation benefits】 Online haze management for plastics, optical films, and glass Cost savings on sampling Improved productivity through rapid feedback during haze value fluctuations
