Color measurement for coated glass
Multiple layers of silver on glass panels give features modern building fronts. Thermal insulation or solar control glass used in all over the world, to reduce the cost of heating or cooling. So far a d: has been used in the laboratory 8 ° meter with gloss (SPCI) to measure glass. Because the surface of the glass panes do not spread, and only the low illumination from the glancing angle at-8 ° provides an useful illumination, all other lighting angle are useless. X-Rite has developed a measuring geometry under the illuminated the glass at an angle and measuring exactly on the other side takes place directly in the gloss. The non-contact measurement allows you to measure without having to mechanically adjust the Messkopf washers of varying thickness.
X-Rite offers two measurement geometries:
Version ERX54 the glass is illuminated with + 15 ° and measured with-15 °. This measurement delivers the same results as in the laboratory with a ball geometry measurement (d: 8 °, SPCI). Not just the reflection can be measured with 2 devices from both sides of the disc but also di transmission.
Version ER56: This instrument offers three measurement geomhttps://www.erx50.com/en/applications/glasetries: + 15 °:-15 °, -45 °: + 45 ° and + 60 ° :-60 °. The 15° measurement delivers same results as in the laboratory with a ball geometry measurement (d: 8 °, SPCI). Measurement provides important information about colour changes under different angles the 45 ° and the 60 °.
