Under sampling › Forums › Spectroscopy › What wavelength error is acceptable with an Alpy? › Under sampling 31 October 2018 at 12:20 pm #580151 Dr Andrew SmithParticipant The error is about 1/2 a pixel. I wonder if it is due to undersampling in which case it will be a practical limit unless you use smaller pixels. Somewhere I have a paper on this and I will try to find it. Regards Andrew
