METHOD AND SYSTEM FOR STANDARDIZING MICROSCOPE INSTRUMENTS
First Claim
1. A calibration instrument for sampling illumination of an excitation light source of a microscopy system, comprising a calibration surface positioned along an optical path to substantially uniformly scatter illumination from the excitation light source toward a detection portion of the microscopy system.

Abstract
Methods and apparatus for standardizing quantitative measurements from a microscope system. The process includes a calibration procedure whereby an image of a calibration slide is obtained through the optics of the microscope system. The calibration slide produces a standard response, which can be used to determine a machine intrinsic factor for the particular system. The machine intrinsic factor can be stored for later reference. In use, images are acquired of a target sample and of the excitation light source. The excitation light source sample is obtained using a calibration instrument configured to sample intensity. The calibration instrument has an associated correction factor to compensate its performance to a universally standardized calibration instrument. The machine intrinsic factor, sampled intensity, and calibration instrument correction factor are usable to compensate a quantitative measurement of the target sample in order to normalize the results for comparison with other microscope systems.
