How did we do it? We tell you about it in these success stories. But first, we want to share with you the most essential points to consider every time a light source is tested at extreme temperatures while in vacuum conditions:
- Perfect alignment of the light source with a light receptor.
- Thermal conductivity between samples and vacuum pot.
- Provide all electrical/optical paths properly to the inside of the vacuum pot.
Sometimes, customers request some particular test over their components, looking to know how they behave in extreme conditions (under vacuum, extreme temperatures, and even in different atmospheres when components are part of interplanetary missions).
Our Optoelectronics department knows how to fulfill this need.
One of our customers requested that we carry a thermal cycling test at extreme temperatures (between 93ºC and -178ºC) over some VIS-NIR calibration sources (five samples at a time). At the same time, these sources were tested in vacuum conditions, and electro-optical characterization at different temperatures during cycling was requested. To go even further, the components needed to be tested in a clean environment.
After ending his studies in 2010, Alejandro started to work as a Test engineer, where he has accumulated more than 10 years of experience. He has developed a career focused on the design/development/execution of test systems for the most leading technology sectors like Aerospace, Aeronautics, and Automotive.
Since he joined Alter Technology in June 2016 as part of the Optoelectronics and New Technologies Department, Alejandro has been in charge of developing complex electronics designs based on FPGA/uP for Image sensors and mixed-signal ICs testing. Still, at the same time, he has been responsible for test setup development and test execution for all kinds of optoelectronics components. Within his framework, he is currently qualifying components for ESA projects like JUICE.
