Generating a Set of Zoom Lenses to Control the Divergence of a Laser Beam
Project Site: HNu Photonics LLC
Mentor: Dan O’Connell, Nathan Sabin
The goal of this project was to make a set of two zoom lenses from SF-11, a soft flint glass with a high index of refraction. There are many steps involved in making lenses. The first step was to edge down the pieces of raw substrate to the proper diameter. The next step was to generate the proper radius of curvature into the pieces and make sure they were the proper thickness, leaving room for the grinding and polishing processes. Then came the grinding process, which took out any damage done while the lenses were being generated. After this, the lenses were ready to polish. When the polishing process was finished, the lenses passed all testing specifications and were sent out to be coated. The result was a set of two lenses that, when put together, form a meniscus lens that causes the divergence of a laser beam. As they are moved apart they start to cause the laser beam to converge. In this way they can adjust the divergence of a laser beam. The processes and tests involved will be discussed in detail.
