The FS2 Systems integrating sphere, coated with Labspheres proprietary highly reflective diffuse Spectraflect, delivers exceptional spatial integration, critical for the uniform, repeatable and reproducible measurements required by the new standards. The system provides lab conditions as specified in the standards, including the ability to calibrate showing traceability to NIST standards.
ANSI FL 1-2009 requires manufacturers to determine and report Run Timethe amount of time elapsed (under continuous operation) at which the devices light output reaches a level when users will commonly replace the batteries. The FS2s unique V-block sample holder ensures the device mates with the measurement port easily, the same way, every time, complying with the requirement that the device to sensor distance be identical for initial and end point measurements. The system software gathers periodic light measurements and records corresponding time values during the Run Time testing.
Labspheres FS2 system determines Total Luminous Flux (Lumens) the total quantity of emitted overall light energy as measured by integrating the entire angular output of the portable light source, as required by the ANSI standard. In addition, the system assesses Total Spectral Flux (Watts/nm), Total Radiant Flux (Watts), Colour (CCT), Lamp Performance vs. Time, Peak and Dominant Wavelength, Spectral Purity, Colour Rendering Index (CRI), Chromaticity Coordinates and Half-Bandwidth.
The systems MtrX-Flashlight measurement software provides a user-friendly, intuitive platform for calibrating the system and analyzing measurements. All measurement results are captured instantly with real time graphics and the ability to generate and export reports.
Labspheres experienced engineering staff are able to specifically address the unique needs of each customer, designing a custom FS2 system for the type of flashlight application under study.
