FIGURE 1. The target spectral-transmittance curve for the optical filters entered in the 2013 OIC Manufacturing Problem Contest is shown in black. The actual performance of the winning filter sample (S1), as measured by the participant, ODA, and NIST, is shown in blue, green, and red (they overlay well enough that the colors are hard to distinguish). This sample, one of the three contest winners, was designed and fabricated at JDSU (Santa Rosa, CA); it had 123 layers and was 8.580 μm thick. The other two winning filters were created at Advanced Thin Films (Boulder, CO) and Nikon Corporation (Tokyo, Japan).
