System and method for correcting spectral response using a radiometric correction filter
First Claim
1. A method for correcting transmission inefficiency of an instrument, the method comprising:
- generating an optical response from a spectrometer-based instrument;
comparing the optical response to a predetermined spectral response for the instrument;
calculating a transmission inefficiency between the optical response and the predetermined spectral response; and
correcting the transmission inefficiency of the optical response by inserting into the instrument a correction filter including a thin film interference filter having a plurality of thin film layers arranged in a predetermined configuration.

Abstract
The present disclosure provides for a correction filter that may be configured to comprise a predetermined arrangement of thin film layers. This arrangement of thin film layers may be such that it effectively enables a correction filter to generate a predetermined spectral response, wherein said predetermined spectral response is substantially the same as a determined instrument response correction associated with an instrument. The invention of the present disclosure therefore provides for effectively compensating for transmission inefficiencies associated with an instrument without the need for separate reference measurements to determine and correct for instrument response.
