rhopoint id

The Worlds First Imaging Transmission Meter Measures Optical Appearance Correlated To Human Vision

Rhopoint ID (Illumination Diffusion) Transmission Appearance Meter is designed and built in response to an industry call to find an improved method for characterising the transmission characteristics of transparent materials. It uses Optical measurement of transparent materials that correlates to human perception.

The cloudy, “hazy” appearance of transparent materials is an important attribute that determines their suitability for applications. For example, packaging materials are typically required to be maximally transparent in order to reproduce the vivid colours and finer details of the product, while for cosmetics a high opacity may be desired. The conventional methods for quantifying the appearance of transparent materials typically employ a dedicated “haze-meter” instrument configured to quantify the amount of light scattered over a certain range of angles from the direction of the incident beam.

Rhopoint ID is available in 2 models

  1. Rhopoint ID-E : Contact model
  2. Rhopoint ID-L :  Contact and Non-contact
