Outlining the Applications of a VIS Spectrophotometer
A VIS spectrophotometer is a quantitative tool for analyzing the visible spectral properties of a sample with outstanding degrees of accuracy. It can acquire the intensity of a light source at wavelengths of between 380 – 780 nm, with integrated processors capable of running independent calculations and providing rapid assessments of a lighting product’s spectral output. Multiple configurations of VIS spectrophotometers exist to enable precise measurements of visible spectra from numerous lighting products requiring specific metrics.
Display Measurements with VIS Spectrophotometers
The hardware of a VIS spectrophotometer can accurately assess the correlated color coordinates according to CIE definitions of a display. The main application for measuring displays with spectrophotometers is to calibrate relatively faster colorimeters used in production lines on target displays, to ensure an overall uniformity between screens of different batches.
LED Measurements with VIS Spectrophotometers
Light-emitting diodes (LEDs) are one of the most broadly used components in the world, with applications in industrial, commercial, and domestic sectors. While LEDs are easy and affordable to produce, differences between batches are inevitable due to the production processes. Binning LEDs is useful to ensure uniformity and consistency in lighting products.
Light Bulb Measurements with VIS Spectrophotometers
The color rendering index (CRI) refers to a light source’s capacity to accurately reproduce the colors of objects respective to natural (day)light. A high CRI value is attractive for applications where accurate color reproduction is required. This may not only be important for general interior lighting but in particular for (fashion) retail.
