Modification to LED colorimeter

Open-Source Colorimeter

The high cost of what have historically been sophisticated research-related sensors and tools has limited their adoption to a relatively small group of well-funded researchers. This paper provides a methodology for applying an open-source approach to design and development of a colorimeter. A 3-D printable, open-source colorimeter utilizing only open-source hardware and software solutions and r...

How to Turn your Scanner into a Colorimeter

We describe a method for converting conventional threechannel flatbed scanners into colorimeters. The method is based on the simple idea of placing a color filter between the image and the scanner sensors and making an additional scan.

Application of a colorimeter for turbidity measurement

Development of Filters for a Thermoelectric Colorimeter

Filters have been designed for use with phoLocells and pho totubes in t ris Limulus colorimeters, but because of the variation in spectral response of t hese detecLors from one Lo t he other, it has not been worthwhile to attempt to achieve the best possible dup li cation or the CIE t ristim ulus func t ions. In t he case of a thermoelectric detector, however, th e response is so nonselective t...
