A lot of variables will dictate the value of the mirror and I would never purchase the cell for the price University charges for it. Nor would I ever purchase an optic from Newport. I am curious as to why you would purchase a mirror and not a corrector blank if not a lense. Anyway a quality crown blank can be expensive a water white plate glass less so. What type of coating what quality of figure?
