A popular optical engineering course equips students with technical and professional skills while putting them on the radar of industry-connected alumni.

professor gave the nearly 40 undergraduate and graduate optics students enrolled in OPT 544: Advanced Lens Design two daunting tasks. First, design the best zoom lens for to explore Jupiter鈥檚 moon. Then, design the ideal zoom lens to record the mission as it blasts off into space.

Bentley鈥檚 students worked on the project collaboratively and competitively throughout the fall semester. They broke into teams to explore the myriad factors that would influence the final lens designs, including the different fields of view, sensors, packaging constraints, and photon budget. Some students helped build tools in programming languages like Python and MATLAB that were first developed in the class more than 10 years ago and each cohort improves upon. Others conducted market research to see what available products could feasibly meet the project requirements.

The result was that the students learned as much about project management, teamwork, and communication as they did about optics. Joanna Rosenbluth 鈥�24, who served as the class鈥檚 lead project manager, found that she loves leading in that role and studied Bentley鈥檚 style closely.

鈥淪he鈥檚 very particular in a good way about wanting everything to be correct, and that really went into my project management style,鈥� says Rosenbluth. 鈥淚t鈥檚 pretty clear when things are wrong and running behind time, so I had checks along the process to make sure no one was getting off track. I learned from her teaching style that if you get a little off track, you can be totally in the weeds, so by keeping everyone moving, we were all able to find a successful design.鈥�

Bentley started teaching the course annually nearly 20 years ago with fewer than 10 students enrolled. , director of the , says the course has grown to become one of the institute鈥檚 most popular, with Bentley teaching her largest cohort ever in the fall. He notes that everyone from third-year undergraduates to PhD students line up to take the class and that it poses a challenge for all.

鈥淚t鈥檚 one of the few courses where they really can compete on equal footing,鈥� says Brown. 鈥淭he undergraduates and graduates take all of the lectures together and put their best foot forward on the project.鈥�

Examples of past projects include exploring lens designs for non-destructive art analysis (2013), underwater zoom cameras for observing coral bleaching (2021), and zoom cameras for canopy animal photography in Africa (2022).

This year鈥檚 project culminated in a marathon four-hour presentation where the small groups outlined the constraints of the project, and each student showcased their final lens design.

And although the class is demanding, Bentley keeps the mood balanced with her trademark sense of humor, peppering constructive feedback with lighthearted jokes. During a pizza break midway through final presentations, she had optics senior Samuel Erdogan 鈥�24 sing one of his parody songs based on Bentley鈥檚 classes鈥攚hich range from 鈥淟ens Design鈥� set to the tune of 鈥淪ilver Bells,鈥� to 鈥淚鈥檓 Sorry Ms. Bentley,鈥� a twist on Outkast鈥檚 鈥淢s. Jackson.鈥�

The work-hard, play-hard mentality seems infectious, and the students know that if they can excel at the challenging class, they might catch the eye of prospective employers.

鈥淲e had about 50 people from 30 different companies in the Institute of Optics鈥� program who listened to the final presentation,鈥� says Bentley. 鈥淭he audience includes former optics students who鈥檝e gone on to work as lens designers at great places. People I know through industry are very interested in these students and get to watch how they perform. We had a bunch of people from NASA as well as Garmin, Optikos, Excelitas, and others. Our students are excited because they want to go get jobs at these companies.鈥�
