Optical Component Spectral Characterization

Traditional component measurements generally do not reflect sensor operating temperature and optical conditions. To determine a sensor’s spectral response, programs usually rely on modeling, simulation, and analysis to apply corrections to component measurements. SDL has designed and fabricated test equipment to measure spectral transmittance and reflectance of optical components under temperatures and optical configurations identical to the sensor design conditions.
