Yes. However, for LED retrofitting to meet industry standards, color- calibrated LED modules must be used for accurate color rendering. We usually do not recommend customers to modify it themselves, as this can affect the accuracy of the color and cause unnecessary losses
The haze meter test assesses the degree of light scattering that occurs when light traverses a transparent or translucent material, producing a percentage that quantifies example or cloudiness.
An inappropriate viewing angle may lead to reflections or color shifts in the light. The correct angle of 45 or 0 will provide the real color of the assessment without the distraction of glare.
Make sure the light sources are calibrated, keep extraneous light sources away, have the correct viewing angles, and handle the samples in a clean and uniform manner.
The number of reflected light is a measure assigned by a gloss meter as a gloss unit (GU). It is a normalized quantity in which 100 GU is normally a perfect reflection at 60°, and 0° GU is a full diffusion.
Usually you will find haze and transmittance standards of ASTM D1003, ISO 13468, & JIS K7105.
You can choose a colorimters depending on the substrate you are measuring the color of, whether it is opaque, translucent or transparent. In short, you can consider the following factors for choosing the right 3NH colorimeter for your needs: Sample Opacity, Physical Form, Optical Properties needed, Measurement Methods required, Scales and Indices needed, Instrument Standards Conformance (ASTM/ISO/Other), Instrument Geometry, Instrument Performance, Location (laboratory, portability, in-process) and Sample Handling requirements.
By systematically addressing these factors, you can select a colorimeter that optimizes accuracy, efficiency, and value for your specific application.Learn more from our ultimate guide on colorimeter selection. If unsure, consult the 3NH manufacturer for personalized recommendations based on your sample and workflow.
