TIA-3000 Reference Standard Detector System

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.

Standard calibrations, directly traceable to NIST, are available for any configuration of the TIA-3000 from Gamma Scientific’s world-renowned standards lab.

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, 3×10 -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.
