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.

Tommorrow’s Metrics, Today

Stay ahead of the competition by incorporating flicker measurements in your suite of optical testing. While still only an emerging requirement in many areas, characterizing flicker will soon become the norm. New metrics like SVM and California Title 24, we have it covered!

A True All-in-One Instrument

Why use multiple measurement devices to characterize your light when it can all be captured with a single portable light spectrometer. Less devices to carry, and less reports to combine. Get it all with the push of a button. Use it to collect spectral and flicker data in the lab or field. Need additional analysis or reporting capabilities? Use our optional Spectrosoft Analysis Suite

Flexibility Re-Defined

The Spectis 1.0 Touch light flicker meter offers a great standalone solution, but can also be paired with a range of accessories. From integrating spheres to goniometers, in the lab or the field, this system has you covered. Configure the system to measure illuminance, flicker metrics or luminous flux and even luminance of LEDs using an optional optical probe.


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.
