Sensitivity Across the Spectral Range
Accurately monitor the dynamic range of your low light cameras with the HELIOSPlus L Family dual detector set up. The SD-S1 and SD-L1 silicon detectors are large active area detectors featuring extremely stable output over a wide range of temperatures and light levels. The L1 offers extremely low light level capability.
Automate Your Testing Routines
Automate your low light testing routines with responsive Hunt & Seek feedback loops using attenuators, detectors, and spectrometers, or impliment Scripting functions for simple programs inside and outside the HELIOSense GUI. HELIOSense Software is the primary interface for HELIOSPlus components and systems. It is a flexible architecture where any hardware built into the Labsphere API (LSAPI) can be recognized and used in HELIOSPlus systems.
