Design and test of fast laser driver circuits

In laser sensor and measurement applications the challenges of the design of fast driver circuits is a very demanding task. This white paper describes the design of fast driver circuits, PCB layouts and optical measurement considerations, as well as a solution to achieve an ideal design for pulses as short as 2.5ns

AC conductivity of CdSSe-doped borosilicate glasses

We report measurements of dynamic (ac) electrical conductivity in borosilicate glasses doped with the semiconductors CdSxSe1-x and AgI in a wide range of frequencies and temperatures. The concentrations of homogenously dissolved dopants are governed by the heat treatment conditions of the glass samples leading to a creation of CdSSe and AgI nanocrystals. The ac conductivity rises with increasing average size of the CdSSe nanocrystals, in contrast to the case of the metal halide doped borosilicate glasses.

Volcano research enhanced with FLIR thermal imaging cameras

Thermal imaging cameras allow researchers to not only see volcanic heat, but also to get non contact temperature readings from a safe distance, which keeps the researchers out of harm’s way.

World-record 100MHz trigger rate photon counter for telecom wavelengths

The id210 is the first photon counter for telecom wavelengths that works at frequencies up to 100MHz, can also operate in free running mode, and does not require cryogenic cooling

Thermal Imaging Scenes with Wide Temperature Differences

This paper introduces and demonstrates the technique of 'superframing'. The technique of superframing consists of varying the exposure, or integration time of a thermal imaging camera from frame to frame in a cyclic manner and combining the resulting subframes into single superframes with greatly extended temperature ranges, thereby allowing the user to visualize scenes featuring wide temperature differences

Near-field goniophotometry supports the development of energy efficient luminaires and solid state lighting

The measurement of luminaires has traditionally been performed with a photometer placed in the far-field, which measures the illuminance from the light source one angle at a time. A near-field goniophotometer exploits the latest advances in imaging photometry and represents a more affordable and flexible option compared with a far-field instrument

Providing Thermal Solutions for R&D and Science
