Ultra-Sensitive Instrument Detects As Little As 10-6 Candelas Per Square Meter Of Luminance And As Little As 0.3 FW Of Optical Power

Gamma Scientific, a leading provider of precision light-measurement instruments, today announced the release of the TIA-3000, a new multi-application, transimpedance-amplifier system. This ultra-precise luminance, night-vision and general-radiometric light-measurement system features interchangeable lenses and filters that enable the user to quickly tailor the system to a wide range of applications.

Luminance Measurement System-TIA-3000Developed under a contract from the National Institute of Standards and Technology (NIST), the TIA-3000 is the most sensitive primary-standard, light-measurement instrument on the market today.

In its luminance configuration, the instrument detects as little as 10-6 candelas per square meter (cd/m2) of luminance and features a temperature-stabilized detector that maintains 0.01% linearity over a dynamic range of more than a 1,000,000 to 1. Total dynamic range spans eight separate decades. Moreover, the optical system enables the user to select any one of six different spot sizes, from 5.0° to 0.1°.

When configured for night vision, the instrument detects as little as 0.3 femtowatts (0.3 x 10 -15 W) of optical power and features a temperature-stabilized detector that maintains 0.01% linearity over a dynamic range of more than a 1,000,000 to 1. Total dynamic range spans eight separate decades.

“The new TIA-3000 is an order of magnitude more sensitive than any similar instrument previously available,” said Richard Austin, president of Gamma Scientific. “This unprecedented sensitivity can lower measurement uncertainty by a factor of ten, enabling faster measurements and ultimately decreasing the cost of performing luminance and night-vision display measurements.”
