High prisicion Optometer

  • Product No:S400 Series
  • Manufacturer:Gamma Scientific

Our flexoptometer is available with a single head or with up to four interchangeable detector heads for optimal flexibility.

Highly configurable via the USB, RS-232, RS-485, and IEEE-488.2 computer interfaces, it is easy to integrate into existing lab instrument architectures. The new light-measuring instrument offers faster, more accurate measurements than any previously available optometric system.

The electronic design is based on Gamma Scientific’s advanced performance, highly reliable, TIA-3000 measurement systems, which have become the primary working standards of several National Standards Labs. The transimpedance amplifier design gives very stable DC measurements down to the femtowatt (10-15 Watt) level. It also includes a pulse-integrator for pulsed energy measurements.

The instrument is designed as a laboratory grade optometer, with the robustness to operate flawlessly on even the most rigorous production lines. The optometer can be configured with Gamma’s extensive collection of optical detectors making it suitable for a wide variety of light measurement applications. Simply put, the flexOptometer is the ideal instrument for measurement applications such as display, LED, laser power, fiber optics, strobe or signal measurements and more.
