PDMS molded glass cell holder with light block (molding and 3D printing).
LED light source in RGB color drived by ATTINY (output).
RGB photo diode sensor sampled by ATTINY (input).
Data sampling in PC (programing and communication).
This is simple optical measurement system for laboratory. The chamber is holder for
glass cell (10mmx10mmx45mm) that contains sample solution. The meter can measure "ABSOBANCE" that
means the absorbing light properties calculated by Log(paased light / injected light).
In this system, three wavelengthes were used for measurement, 450, 520 and 620nm in wavelength.
The embeded micropocessor board controls LED and photosensor, calculated asobance and
send result to PC via USB or wireless connection.
