The idea is to make a cheap, robust, reliable alternative to a dedicated and expensive device. The initial brain storming is to take a 600 nm source, (or a broad wavelength source of light which includes 600 nm and use a BP filter) and a level detector, and calibrate it to match 0.4 at OD600 on a proper spectrophotometer.. | The idea is to make a cheap, robust, reliable alternative to a dedicated and expensive device.
