Microscope

hello,
Please if you have any information, is it required make validation of a microscope and in which the document is it indicated ?

I would assume to write a validation of a microscope would just be a IOQ - Verification of a the installation, all components, location etc… The OQ would test all of the functions of the microscope, verifying the calibration if applicable and verify all the lenses with a calibrated slide… etc. Again I am just assuming as I have never had to write one, but that is how I would go about it and start.
