The Ultimate Portable Light Spectrometer

 An upgraded version of the very successful Spectis 1.0 Touch spectral light meter, this new variant takes portable light measurement to a new level. This innovative new light spectrometer instrument can now measure flicker of light in addition to the extensive range of standard photometric and colorimetric values available on the Spectis 1.0 Touch for color and intensity…all within seconds.
The Spectis 1.0 Touch light flicker meter is now equipped with additional electronics and fast photodiode to measure flicker frequency, flicker index and flicker ratio. Designed and developed in consultation with industry leaders and standards committees, this device provides all the measurement quantities required to accurately measure and understand flicker.

GL SPECTIS 1.0 Touch + Flicker Usage

 Every Important Metric, One Device

When the first “flicker-free” football stadium lighting was installed at Chelsea Arena in the UK, GL Optics was asked to provide a device which could be used as an auditing tool to check the newly installed lighting. The contractor needed to evaluate the photometric and colorimetric values including illumination (lx), color temperature (CCT), color rendering properties of LED (CRI), television index (TI) and additionally verify if it was a flicker-free installation.

This project triggered the development of the Spectis 1.0 Touch + Flicker, improving on our existing GL Spectis 1.0 Touch by integrating an additional electronic circuit board with the fast photodiode to capture the optical flicker characteristics. The result is possibly the best hand-held flicker spectroradiometer on market. Covering an exceptional wide range of frequencies with accuracy equal to some laboratory devices.

GL Optic takes an active part in a Philips Working Group which is focused on establishing new flicker metric standards throughout the industry. Thanks to this direct cooperation we have an opportunity to compare and evaluate our accuracy daily using the reference standard provided by Philips. We are also able to include the latest flicker metrics like Flicker Index, Flicker Percent and the Flicker Ratio together with the latest SVM (Stroboscopic Visibility Measure) – a new standard to assess how the lighting installation might influence human visibility performance.

The GL Spectis 1.0 T Flicker meter is an intuitively operated touch screen portable light spectrometer, equally suited to the lab as it is in the field. With a range of software analysis capabilities and extensive suite of accessories, this device is in a category all its own.

GL Spectis 1.0 Touch + Flicker Meter Features

Reliable, precise and intuitively operated spectral instrument

The Spectis 1.0 Touch Flicker meter delivers reliable and accurate optical performance, and intuitively operated spectral instrument for light measurement. Dependable light assessment is no longer restricted to only experts or external laboratories. Our preconfigured, individually calibrated measurement instruments deliver fast and precise results, and the included software includes extensive analysis and automation capabilities that deliver the results that matter.

 Spectral and Photodiode Measurement

GL Optic light spectrometers are designed and preconfigured for light measurement applications. The B class cosine corrected measurement head is a standard accessory allowing for precise measurement of light. Now, with the addition of a photodiode placed next to the standard diffusor with fast readout electronics, optical flicker signal response is captured at the same time. Directly on the touch screen you can check the values and the graph showing the wave shape, height and frequency and you can even zoom in to check details. Extended analytical and reporting capabilities are possible with the optional GL Spectrosoft PRO license.

 Plus all of the core features of the Spectis 1 Touch:
  • Self Contained Handheld Spectrometer
  • Automatic Accessory Detection
  • Dark current compensation
  • Trigger Socket
  • Photometric and Radiometric calibration
