HELIOS® Plus-VM Variable Manual Systems

Simple, complete turn-key radiance sources with excellent dynamic range.

Features:

·      Broadband 3000K black body like spectrums
·      Great well-rounded radiance source for simple sensor testing
·      Spare ports and future upgrade capability
·      Manual Micrometer Variable Attenuator, VA-MM, on all systems
·      Angular uniform FOV 35° +/-2.0%

The HELIOSPlus-VM, V Family systems are simple and complete turn-key systems with excellent dynamic range. A single lamp, manual attenuator and detector give you the ability to completely characterize your sensor/imager over its full dynamic range from moonlight levels to albedo 1.5.

NOTE: Depending on the application and the desired uncertainty levels, custom calibrations may be required to characterize the system under different operating conditions. Our application engineers would be happy to discuss this with you and help define the best system and calibrations to meet your requirements.
