goniophotometer robogonio

Quick. Precise. Highly flexible.

We invite you to visit the opsira lightlab and watch the robogonio measurements live. Just contact us to fix a date. We are looking forward to meeting you.

Its degrees of freedom enable the robogonio to combine several goniophotometer types in a single instrument (DIN 5032-1, DIN EN 13032-1,
CIE 121). In the far field, the robogonio measures the luminous intensity distribution, while conventional data such as EULUMDAT or IES are generated directly. In the near field, the robogonio generates ray data with high precision, and even polychromatic depending on the detector. Angular dependent luminance measurements, for example, form the basis for glare ratings. Mounted on the robot arm, the detector can scan any geometry, including planes, by means of an add-on also the total luminous flux of the non-rotating light source or luminaire.

One system, six good reasons
What the robogonio can do - overview

1. Highest flexibility

Goniophotometry in near and far field, various detector systems – combined in one instrument.

2. Extremely quick scans

The class L photometer reduces the measurement time. This means for example: Half-space within approximately two minutes.

3. Variable sizes

The robogonio is available in seven basic variants (6, 10, 16, 30, 60, 120, 240 kg), special models of up to 1,000 kg are possible. Our experienced partner for robotics: KUKA Roboter GmbH

4. Maximum precision

The robogonio offers the highest angle repeatabilities of 0.005° along with a photometer of the highest class (L).

5. Intuitive operation

The robogonio is easy to use. Complicated and error-prone measurements with mirror goniophotometers are a thing of the past.

6. All-round carefree package

We're always there for you — from the complete planning of your system to competent after-sales support.

The right size and configuration for every task.

The robogonio is available in seven basic sizes for different payloads: 6, 10, 16, 30, 60, 120 and 240 kg. Even payloads of up to 1,000 kg are possible upon request. The smaller models are designed for measuring the luminous intensity distribution of luminaires and LED PCBs as well as for generating near-field ray data. The larger models are suitable for systems such as street lights, stage lights, and headlights.

safety & innovation under high time pressure

The robogonio for automotive.

The robogonio is the perfect device to cover two central requirements of the automotive industry: It quickly provides authoritative results since the high-end photometer performs classic goniometric measurements within minutes. For standard-compliant verifications of cut-off lines, measurements with extremely fine angular resolutions of down to 0.01° are possible.

Due to its spatial flexibility, the robogonio can also cover different headlight functions such as high beam, low beam, or direction indicators in a single measuring run. All measuring points according to ECE and SAE are scanned by the system automatically.

On top: For measuring elongated light guides, the robogonio scans the light guide with a high-resolution camera and thus conveniently provides high-precision results on the luminance distribution.

shorter r&d cycles, eulumdat & ies in view

The robogonio for lighting.

Accelerating the development of new products, providing far-field data according to EULUMDAT and IES for light planning, and quickly generating LED data: These are the robogonio's strong points in the field of lighting. While the luminaire is warming up in operating position, the run-up curve (DIN EN 13032-4) is provided by the auxiliary photometer. Then the luminous intensity distribution can be measured through any angle in the C-plane system since the robogonio moves freely in space. After measuring, the robogonio puts the luminaire back into the specified burning position for the final measurement according to the standard EN 13032.
Color-over-angle measurements are possible with the optional spectrometer. So optics designers can determine how the color changes at certain angles, and whether unwanted color effects occur. Luminous flux efficiency in lumen/watt and energy efficiency classes can also be determined directly.

On top: The robogonio also helps with the glare rating of luminaires.

Light on the spot, reliable and accurate

The robogonio for signal lights.

For measuring traffic lights, railway signals, beacons, or signal towers for production, the focus must be on luminous intensity distribution. An additional challenge presented by certain applications: The front and back light exit windows have to emit the exact required quantity of light. Since it can control the luminous intensity distribution in both directions using arbitrary centres of rotation in space, the robogonio carries out all necessary measurements easily and precisely. The robogonio scans standard-relevant test ranges according to ICAO, FAA, and DIN EN 12368 fully automatically.

On top: User-defined measuring processes can be integrated in the robogonio as well as the numerous updates of standards.

Realistic simulation of optical systems

The robogonio for optics design.

All lights are different – a dilemma many optics designers are familiar with in the preliminary development. At the same time, systems are getting smaller and smaller – the key word here is LEDs. The robogonio measures light sources with a high-resolution luminance camera from 10,000 different angles. This leads to reliable near-field ray data that can be used in all standard optics simulation environments.

On top: The robogonio is the only goniophotometer available that can do actual far-field and near-field measurements in one single instrument. Thus, the robogonio accompanies developers and producers from the first idea throughout the development and to the finished product.

all angles covered

One goniophotometer - all coordinate systems.

The high flexibility of the 6 axes enable the goniophotometer robogonio to combine several goniometer types (DIN 5032-1, DIN EN 13032-1 und CIE 121) into one single device. Especially Type 1.1, 1.2 and 1.3, where the detector remains in its position while the sample (light source, luminaire, display, etc.) is moving around the vertical and horizontal axis, can be realized by the goniophotometer robogonio extremely easily and precisely.

The robot's variability allows the detector to be fixed anywhere in the lab room. Larger distances between detector and sample are possible thus. Even large luminaires can be measured easily and still very precisely within the far field. Goniometer types 2, 3 and 4 are also able to be realized if required.

multiple light measurement applications

one goniophotometer - multiple light measurement applications.

The high flexibility of the 6 axes enable the goniophotometer robogonio to combine several light measurement applications into one single device. The measurement of luminous intensity distributions of luminaires in the far field and the generation of all conventional far field data such as Eulumdat, IES and others is as easy as the precise measurement of ray data of light sources in the near field, also polychromatically depending on the detector. Many users will also be interested in the angle-dependent luminance information, which can be used to evaluate glare.

Besides the conventional goniometer movements, the scanning of planes or other shapes is also possible by mounting the detector on the roboter arm, which scans the desired shape. This is very helpful to evaluate the luminous intensity distribution of luminaires and flood lights.
And all of it in only one device: one investment - multiple solutions!
All measurement applications run with the same easy to use software.

flexible and scalable

the goniophotometer with flexible sizes, weight and measures.

There's the right size for you whatever you need:
Whether you need to measure large linear luminaires, small LEDs, heavy sun simulation flood lights or bulky street lamps. The robogonio goniophotometer's scalability is almost unlimited, whether you work with the typical nominal payloads of 6, 16, 30, 60 or 90 kg or with high nominal payloads of 1000 kg - and the robogonio still measures with high precision! The angle repeatability of a 16 kg nominal payload robogonio lies at 0,005°, certified by the Technical Service for Testing of Lighting Devices (TÜV).

Furthermore, various mounting positions can be realized, e.g. wall-, floor-, ceiling- or even rail system mounting.

All this makes the goniophotometer robogonio a flexible and efficient assistant in terms of the evaluation of all necessary lightsource and luminaire parameters. With its excellent cost-performance ratio the goniophotometer robogonio introduces the next generation of goniophotometry.
