ILLUMINATION MEASUREMENT [lx]
Irradiance measurement [mW/m2 ]
All spectrometers offered by GL Optic are calibrated and provide absolute values.
The cosine corrected measurement head is designed for the precise measurement of illumination levels and conforms to the requirements of DIN 5032 Part 7 Class B. According to Lambert’s Cosine Law the radiant intensity observed at a “Lambertian” surface is directly proportional to the cosine of the angle between the incoming light and the normal to the surface.
Therefore it is absolutely necessary for the illuminance meter to include a cosine correcting head to eliminate measurement errors which may arise when the light source is not directly above the sensor, but at any angle within the hemisphere of measurement.
What is illuminance?
It is the total luminous flux incident on a surface, correlated with the human brightness perception.
How is it measured and which unit is used?
It is measured using a spectrometer with a cosine-corrected measurement probe called a diffuser. It is placed on an examined surface and measures the luminous emittance in lux [lx].
What does it give us?
It is a very practical method of determining the level of light on surfaces like work tables, pavements, roads or shelves.
Illuminance is inversely proportional to the square of the distance from the source.

+ LUMINOUS FLUX MEASUREMENT [lm] Radiant power measurement [mW]
GL OPTI SPHERE 48
Measure radiant power, luminous flux, color temperature, color coordinates and color rendering index (CRI) of LEDs.
GL OPTI SPHERE 48 for single LEDs
GL Optic offers a unique solution for luminous flux measurements, color CRI and TM30 rendering properties of LEDs of single LEDs.
GL OPTI SPHERE 48 is an accessory that can be combined with our spectrometers to create a portable measurement set.
Did you know that electric current, electronic drivers and even heat may negatively affect the lighting properties of LEDs?
These are some of the reasons why you would need an integrating sphere to measure the performance of single LEDs once they are installed on the PCB.
This compact and portable set can be carried in a case, so you can bring it to meetings with your suppliers or customers.
What is luminous flux?
It is the total measurement of the perceived power of light in relation to the spectral sensitivity of the human eye.
How do we measure it?
Luminous flux is measured with a spectrometer connected to an integrating sphere. This method allows us to determine the total amount of energy emitted by an examined source in all directions.
The SI unit of luminous flux is lumen [lm].
What does it give us? It allows us to determine the total amount of light emitted by a source in every direction, taking into account the sensitivity of the human eye.
Such a measurement provides a basis for calculating other parameters and can be used for comparing different light sources
+ LUMINANCE MEASUREMENT [cd/m2 ]
Luminance and Radiance
Available luminance optical probes can be connected and calibrated with our device to measure flat emitting surfaces like displays, screens and back lights.
The coding system installed in our spectrometer will automatically download calibration file and measure cd/m2.
GL OPTI PROBE 1.0.10 LUMINANCE for display measurements
GL OPTI PROBE 1.0.10 LUMINANCE is an accessory which is designed to be used with our GL SPECTIS 1.0 Touch for luminance measurements of flat displays, LCD and LED panels, as well as plasma FPDs.
It is also the perfect solution for testing projection displays as well as OLED light sources.
The measurement provides accurate readings of luminance [cd/m2 ] and color coordinates (x, y, Y) conforming to CIE standards.
This accessory connects to the spectrometer with fiber optic connection and can be installed on a tripod at a distance from the test device or put directly on the LED or OLED surface to measure cd/m2, SPD and radiance.
What is luminance?
Luminance is a photometric measure of luminous intensity of light that is emitted or diffused by a particular area.
How is it measured and what unit is used?
It is measured with a lens directed towards the examined surface. The SE unit is candela per square meter [cd/m²].
What does it give us?
It allows us to assess the brightness of a particular surface and is especially useful when measuring the brightness of screens and displays, airport aprons and runways, roads lit with street lamps, etc.
GL SPECTIS 1.0 Touch + Flicker Usage
Every Important Metric, One Device
TV and Studio Light Flicker
Use our GL Spectis 1.0 Touch light spectrometer + Flicker to measure very high frequencies up to 12 kHz which are important for broadcasting and studio lighting evaluation. This will also include CCT, CRI and TLCI indices verified.
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.
