Optical Interference Coatings Conference

The Optical Interference Coatings conference sponsors three contests in the areas of design, manufacturing, and measurement.  Following are the descriptions and submission information for each of the three contests.

Design Contest

An exciting component of the Optical Interference Coating (OIC) topical meeting is the design contest. The contest traditionally presents two challenging design problems to the optical thin-film community. The participating designers can use whatever design software or design techniques they prefer in order to meet the specifications called out in the problem statement. Web-based evaluation software will be provided to participants to check their results. An examination of all of the design techniques and submitted solutions provides valuable insights and helps to advance the knowledge base of the optical thin-film community. The design contest results will be presented at the OIC conference. The designs and associated designer list will be disclosed.

Manufacturing Contest 

The purpose of the Manufacturing Contest is to demonstrate the state-of-the-art in optical thin film manufacturing by challenging participants to manufacture a demanding optical filter. The contest has attracted many participants in the past from industries, research organizations and universities since it was first held in 2001. Participants can use any optical design, deposition technique and measurement equipment to manufacture the filter on supplied blank substrates according to the specification in the contest description. Three independent laboratories will evaluate the submitted samples only for the required performance rating and samples will be returned to participants at the OIC conference. The manufacturing contest results will be presented at the OIC conference. As in the previous contests, only the participant with the top-rated sample will be named. All other participants will be acknowledged, but not associated with a specific sample.

Blank substrates: Available in early November 2021
Submission deadline: 11 February 2022


Measurement Contest 

The ability to measure accurately the performance of optical coatings is essential to the successful design and manufacturing of optical coatings, especially for demanding applications. The OIC Measurement Contest challenges participants to use whatever techniques or equipment available to them, to measure the performance of supplied coating samples according to the specification in the contest description. The samples supplied by the contest are fabricated by durable deposition process and have passed a durability test before being distributed to participants. The submitted measurement results by participants will be presented at the OIC conference in an anonymous manner. All participants will be acknowledged.
