In a low-cost consumer camera, stray light may be only a minor annoyance, but in a space-based telescope, it can result in the loss of data worth millions of dollars.

Home Calibration Quality Control. Ankur Choudhary Print Question Forum 1 comment. Ensure that the connections of the spectrometer are proper. Measure the absorbance of potassium dichromate solution at the wavelengths given below. Acceptance criteria Wavelengths nm. Resolution power Record the spectrum of a 0. Acceptance criteria The ratio of the absorbance at the maximum at about nm to that at the minimum at about nm is not less than 1.

It is imperative that optical system designers understand its consequences on system performance and adapt the design process to control it. This book addresses stray light terminology, radiometry, and the physics of stray light mechanisms, such as surface roughness scatter and ghost reflections.

Method of controlling optical surface roughness based on stray light requirements. SPIE Therefore, the optical designers are required to provide a roughness index for describing the specific surface or even all surfaces to ensure the final imaging performance. The surface root-mean-square RMS roughness is a common index to quantify surface topography.
