Variable Output Systemsfor Basic Testing Needs
HELIOSPlus-VM V FAMILY

Dynamic manual systems with variable levels
The HELIOSPlus-VM, V Family systems are simple
yet complete turn-key systems with excellent
dynamic range. A single lamp, manual attenuatorand detector give you ability to completely
characterize your sensor/imager over its fulldynamic range. The V Family is based on the same
components as the more advanced D, A and L familysystems allowing for easy upgrades as your test needs
expand. The V Family systems are robust foundation
for starting your testing lab.

Value:• Great all-round source system for simple

sensor testing• Straight-forward operation with high performance• High level of absolute characterization• Spare ports and future upgrade capability• Easy to upgrade to other system options

or family configurations

Performance:• 3000K QTH 250 - 2500 nm black-bodylike spectrums• Good Dynamic Light Range:>Albedo 1.5 (AM 1.5) down to moonlight levels- Cameras and sensors >14bit,
actual 15bit (93dB)- Manual level control
