I would like to know if any one know about a Monochromator and Stepper Motor?
Answer:
Dont know what a monochromotor is, but monochro- is one time (synchronous) and a stepper motor is a motor where there are individual coils that u actuate to move the axle one step at a time, like a sixth of a turn. Also, monochrom can mean one color, but that doesnt seem to make sense here
I know about stepper motors. :)
A monochromator takes light of many frequencies as input and outputs a narrow range of output. A prism could do this if you used shields to block off the wavelengths that are too long or too short.
Steppers are used to rotate a motor a specific amount of arc.
Last time I used a monochromator was in an UG lab investigating the photoelectric effect. (Relationship between different wavelengths and energy of emitted electrons.) As far as I can recall it consisted of a prism rotated manually. Suppose you could use a stepper motor to control and fine tune/automate the process.
