Optoi has developed hermetic optocouplers, in previous activities funded by ESA.
On a first project, the devices have been subjected to a full ESCC campaign following ESCC 2265000. This activity allowed the determination of the device’s functional boundaries and included a radiation campaign.
Laser screening tests are done to comply with users’ requirements; two different challenges must be addressed. First, high-power lasers (30watts in this case) require specific test setups and important safety considerations to avoid dangerous situations in case of DUT/setup failure.
Exposure to vacuum may cause changes in filling isolating materials even at room temperature conditions. HV Optocouplers are used to connect two different circuits while maintaining high electrical isolation between them.
