GL SPECTIS 1.0 Touch + Flicker
Flicker measurement simplified
The ultimate portable light spectrometer
An upgraded version of the very successful GL SPECTIS 1.0 Touch spectral light meter. This variant takes portable light measurement to a new level. This innovative light spectrometer instrument can now measure flicker of light in addition to the extensive range of standard photometric and colorimetric values available on the GL SPECTIS 1.0 Touch for color and intensity… all within seconds.
The best choice for flicker measurement
GL 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! Read more about flicker measurments and new requirements on GL blog.
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 GL SPECTROSOFT M.
Flexibility for leading industry
GL 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 Optic 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 GL 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 handheld flicker spectroradiometer on the market. Covering an exceptional wide range of frequencies with accuracy equal to some laboratory devices.
GL Optic takes an active part in a Philips (currently Signify) 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 flicker frequency together with the latest SVM (Stroboscopic Visibility Measure) – a new standard to assess how the lighting installation might influence human visibility performance.
GL SPECTIS 1.0 Touch + Flicker meter is an intuitively operated touchscreen 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 Features
Reliable, precise and intuitively operated spectral instrument
GL 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.

* Dynamic range is spectrum related and should be calculated separately for any light source. Estimated dynamic range for typical 4000 K white LED. Range estimated for optical system made to default specification. Alterations of that are often possible. Please consult technical support if you are looking for specific parameters.
** Spectral range of the sensor. Actual spectral range of system may be reduced due to limitations of used optical accessory.
*** Absolute measurement uncertainty immediately after calibration. The expanded uncertainty corresponds to a coverage probability of 95% and the coverage factor k = 2. Parameters valid in laboratory conditions 25°C, relative humidity 45%.
**** Applies only within the spectral range of the given model.
***** In moderate use – continuous measurements and WiFi significantly increase energy consumption.
