Radiation Detectors


Radiation detectors utilise silicon photodiode technology but with the addition of a crystal or membrane of scintillator material. Scintillators convert the higher energy x-rays into the visible spectrum, which can then be detected by a photodiode.

Custom detectors:
• Designed to suit customer-specific applications
• Excellent response to Gamma, Beta and X-ray radiation
• Design, test and manufacture of complementary ASICS for use with your radiation detection system

Standard Packages:
• TO can packages
• Surface mount LCC packages

Custom Packages:
• Scintillators
• Filtering
• Signal conditioning electronics
• Multi element arrays
