danbeavers "It is supposed to be a Raman spectrometer. What are the capabilities of that technology with 1 stimulus frequency? This is beyond my knowledge. " | Read more » over 10 years ago

danbeavers "Chris, I am referring to the rotational alignment between the slit axis and the grating's ruling. What is the effect when the angles are rotated? " | Read more » over 11 years ago
danbeavers "Great investigation! Another question is slit to grating angle. What effect does that have? What are the symptoms of misalignment? " | Read more » over 11 years ago
danbeavers "I conjecture that you just have an alignment problem. My suggestion would be to fix the laser and scope alignment and then move the spectrometer a..." | Read more » over 11 years ago
