MKS Announces Ophir® FGC100, NIST Traceable LED Calibration Standard

MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, announces the Ophir® FGC100, a NIST-traceable LED calibration standard designed to calibrate the Ophir® FluxGage™ system.

FluxGage is a compact, all-in-one LED luminaire measurement system that measures flux, color, and flicker, important quantities for evaluating the performance of LED-based products.

FluxGage is used instead of large, cumbersome integrating spheres during development and production, and for incoming inspection and quality control of new and replacement parts, allowing LED luminaires and modules to be sorted for consistency.

The FGC100 is a current- and temperature-stabilized LED source that calibrates total spectral radiant flux from 390 to 800 nm. It includes a lamp unit and controller. The lamp unit is a forward emitting source.

A special fixture in the FluxGage cover ensures repeatable mounting and calibration.

To ensure reliability, the FGC100 is calibrated at Ophir using a NIST-traceable source. The spectral flux data is provided on USB drive.

The FGC100 controller includes an hour meter that indicates the total working time of the unit. After 50 hours, the FGC100 should be sent to Ophir for recalibration.

The FluxGage system measures LED luminaires and, therefore, needs an LED calibration standard as opposed to the typical tungsten standard.  This does away with a number of major calibration uncertainties. There are no longer spectral and angular distribution mismatches between the tungsten standard and the measured LED sources. Stray light in the spectrometers is eliminated by removing the excess infrared radiation emitted by tungsten sources.
