A beautiful new DM

By Thomas G BifanoAugust 11th, 2018

My friends and colleagues at Boston Micromachines Corporation (BMC) just delivered a flawless 2000 actuator deformable mirror to NASA, as part of the Wide Field Infrared Survey Telescope (WFIRST) technology development program. WFIRST is an  observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. Congratulations BMC!

Extended depth-of-field microscopy with a high-speed deformable mirror

By Thomas G BifanoAugust 28th, 2017

Paper in Optics Letters:

We present a wide-field fluorescence microscopy add-on that provides a fast, light-efficient extended depth-of-field (EDOF) using a deformable mirror with an update rate of 20 kHz. Out-of-focus contributions in the raw EDOF images are suppressed with a deconvolution algorithm derived directly from the microscope 3D optical transfer function. Demonstrations of the benefits of EDOF microscopy are shown with GCaMP-labeled mouse brain tissue.

Summer design project: Keep EpiPens cool

By Thomas G BifanoAugust 28th, 2017

EpiPens need to be kept within narrow temperature limits. They cannot be refrigerated, nor are they allowed to exceed 86°F. This summer we developed a low-cost, do-it-yourself solution for keeping EpiPens cool on summer outings. A short YouTube video highlights the results.

Photonics Center Launches New Neurophotonics NRT led by Professor Thomas Bifano

By Beth MathisenJune 22nd, 2017

The Photonics Center was awarded a NSF National Research Traineeship (NRT) by the National Science Foundation.  The NRT: Understanding the Brain: Neurophotonics, is led by Professor Thomas Bifano.  This is a university-wide community of doctoral students in biology, neuroscience, biophysics, biomedical, and mechanical engineering with focused professional development and graduate training in neurophotonics.  Learn more about the program.
