Tandem Solar Cell Demonstrates 29.15% Efficiency
Scientists at Kaunas University of Technology have achieved 29.15% efficiency in a solar cell made of perovskite and silicon. This value was certified by the CalLab of the Fraunhofer Institute for Solar Energy Systems. It represents a new world record for a tandem solar element, the KTU researchers said.

Hybrid Microscope Improves Tissue Pathology
Researchers at the University of Illinois at Urbana-Champaign have paired infrared capabilities with high-resolution optical microscopy and machine learning to bring cancer diagnostics into the digital era. The researchers developed the microscope by adding an infrared laser and a specialized microscope lens called an interference objective to an optical camera.

Portable Device Uses Photomultiplier to Detect Foodborne Illness
Researchers at Purdue University have developed a bioluminescence-sensing assay coupled with a portable light detection device that works with smartphones and laptops to do on-site testing for E. coli in food samples. To facilitate the use of a silicon photomultiplier (SiPM) in a portable, field-deployable device, the researchers designed an electrical circuit consisting of an amplifier, comparator, and microcontroller.

Optical Design and Fabrication: Considerations for Going Custom
Tue, Feb 25, 2020 1:00 PM - 2:00 PM EST
This webinar will address the items to consider when designing and fabricating a custom lens for any given system. Presenter Stuart Singer, chief executive officer at Schneider Optics, Inc., will review the basic parameters and specifications required to analyze a possible commercial off-the-shelf (COTS) lens solution, a modified COTS lens solution, or lens solutions that are fully modified to meet your requirements. He will review basic optics principles and provide practical guidance on optical specification, and will address custom lens design fabrication tolerances with regard to cost and feasibility for single application as well as serial mass production. You will learn how to convey your requirements to an optical design/fabrication company to obtain meaningful quotes and a full understanding of your options. Sponsored by LaCroix Precision Optics, Applied Optics Center, ZYGO, and Precision Glass & Optics.
