Flexible, Adaptable, Adjustable
Evolve your testing with the flexibility of the HELIOS®Plus V Family. The core of all HELIOS®Plus V Family systems is a halogen external source (HES) lamp. The HES sources are the operative solution to translate light levels without changing current and spectrum when combined with the manual variable attenuator on the V Family systems. These optimized light units are thermally stabilized, quiet, almost completely light tight and provide a stable spectrum at 3000K from 300 – 2400 nm.

Automate Your Testing Routines
Simplify your R&D testing routines with HELIOSense. 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.
