Microtiter Plate Reader
We are interested in using our spectrometer to build an optical reader for microtiter plates. This page shows our work to build one that incorporates our WheeTrometer spectrometer with an x-y stage and a 1 x 8 matrix of white LEDs. This prototype is not ready for market, but I wanted to show you where we are going. I think that all of the hardware shown works, but we are a long way from having software ready for it.
The reader will move the spectrometer and plate to read specific wells, turn on the led directly beneath that well, and record the spectrum of that solution.
The instrument uses the Teensy 4.1 to control the spectrometer and the x-y stage and the leds. The motors are controlled using tmc2209 motor drivers.
