Participants in the 2022 Manufacturing Problem Contest were challenged to fabricate an optical filter with a specified stepped transmittance spanning three orders of magnitude from 400 to 1100 nm. The problem required that contestants be versed in the design, deposition, and measurement of optical filters to achieve good results. Nine samples from five institutions were submitted with total thicknesses between 5.9 and 53.5 µm with between 68 and 1743 layers. The filter spectra were measured by three independent laboratories. The results were presented in June 2022 at the Optical Interference Coatings Conference in Whistler, B.C., Canada.
