Optical system calibration verification

摘要

A sample processing apparatus (102) includes a reference carrier region (106) that supports a reference carrier (108), which includes one or more reference substances that emit radiation with unique and known spectral characteristics in response to being irradiated with radiation having a wavelength in a predetermined range of interest. The sample processing apparatus further includes a carrier receiving region (110) configured to alternatively receive a sample carrier (104) or the reference carrier for processing by the apparatus. The sample processing apparatus further includes an optical component (114, 116, 118) that emits radiation, having a wavelength in a predetermined range of interest, that irradiates the carrier in the carrier receiving region, and that detects the radiation emitted from the carrier. The apparatus moves the reference carrier from the reference carrier region to the carrier receiving region for processing by the apparatus.

1. A sample processing apparatus, comprising:
a reference carrier region that supports a reference carrier, which includes one or more reference substances that emit radiation with unique and known spectral characteristics in response to being irradiated with radiation having a wavelength in a predetermined range of interest; a carrier receiving region configured to alternatively receive a sample carrier or the reference carrier for processing by the apparatus; and an optical component that emits radiation, having a wavelength in a predetermined range of interest, that irradiates the carrier in the carrier receiving region, and that detects the radiation emitted from the carrier, wherein the apparatus moves the reference carrier from the reference carrier region to the carrier receiving region for processing by the apparatus, and wherein the apparatus includes a DNA sequencer.
