I am looking for optoelectronics that will work next to each other at different wave lengths so that they will not have cross-talk. That is, I would like to use two IRLED/Phototransistor pairs next to each other as close as I can get them.
Does anyone sell them at different frequencies such that the phototransistors can be real close to each other and not see the other IRLED's signal? Are there filters that I could use to minimize cross-talk?
This application is for liquid level measurement through a quartz container :idea: .
