FM-100
The FM-100 Flash Measurement Photometer System allows maintenance personnel to measure flashing light sources such as aircraft anti-collision strobes, highway safety strobes and barricade lighting, to ensure they meet output requirements.
The FM-100 measures the illuminance of each pulse in a string of light pulses at a rate of up to 700 per second, at pulsewidths from 1 nanosecond to 30 milliseconds. Sensitivity of the pulse luminance intensity measurement ranges from 11 millicandela-seconds at one meter to over 50,000 candela-seconds at 15 meters without additional detector attenuation. The FM-100 selects the optimum pulse measurement time for varying pulse widths.
The easy-to-use Windows 95/98/NT software interface allows direct logging of effective light intensity. A unique optional high-speed sensor connects to an oscilloscope for light-flash shape and analysis.
The FM-100’s ability to control a temperature-stabilized detector assures best agreement with NIST standards. Detector match to human eye response is guaranteed better than 3 percent using the CIE f1' method

TIA-3000
The TIA-3000 Measurement Systems are detector-based absolute standards for a variety of high-accuracy measurements. Off-the-shelf configurations include thermo-electrically cooled silicon and indium gallium arsenide (InGaAs) detectors. Options include high-accuracy photometric correction filters (f1' ~0.8%), flat-response filters, trap detectors and ANVIS-compatibility filters with field-of-view lenses making the TIA-3000 the standard for any light measurement requirement.
The heart of the TIA-3000 is its transimpedance amplifier. The state-of-the-art design of the transimpedance amplifier allows for extremely low dark-current levels (3 femptoamps, 3x10 -15 amps, at room temperature with the silicon detector) and excellent stability. This stability and sensitivity is 10 times more sensitive than anything else previously available, making it the ultimate tool for any standards lab.
Standard calibrations, directly traceable to NIST, are available for any configuration of the TIA-3000 from Gamma Scientific’s world-renowned standards lab.
