The transparency of substances with narrow scattering properties, such as plastic films, may not be measurable with a haze meter or may not correspond to visual perception. The CL-1 model allows for easy comparative measurement of the transparency of these narrow scattering materials due to its unique optical system. Additionally, since the measurement section can be rotated, it is also possible to measure the changes in transparency of anisotropic samples at different angles. ■ It demonstrates its power in measuring the transmittance of highly transparent samples (haze value of 1 or less) where no differences can be detected with a haze meter. ■ By adopting an LED light source, the lifespan of the conventional light source has been extended to 20 times longer (40,000 hours). ■ The design of the housing has been completely renewed, allowing for the measurement of the center of A4 size samples, which was not possible with the old model. ■ By using optional software, data measurements such as maximum transmittance, minimum transmittance, and average transmittance can be performed. * The rotation mechanism cannot be used during liquid measurements.

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
