Goniophotometer - gonio'2pi and gonio'4pi

opsira's goniophotometers record angular dependent photometric parameters around a light source, a luminaire, a detector or a material sample. We offer uniaxial In-Plane goniophotometers as well as 3D-goniophotometers up to 4-axis. The compact construction of our goniophotometer type gonio'2pi allows a measurement of the hemisphere. The 4-axis goniometer even enables a fully automated complete measurement of an anisotropic scatter sample. The gonio'4pi is available for full sphere measurements without turning the sample. About 99,5% of the complete 4π solid angle can be measured. All goniophotometer types work with an angular accuracy of 0,0001º. The solid construction as well as the direct drive concept introduced and consequently implemented by opsira guarantees a very high accuracy and precision from our goniometer systems. Photometers and radiometers, the luca luminance measurement systems, the spectral measurement systems spec'3 and SPR'3 as well as high-quality photomultipliers are available as detectors.

Goniophotometer robogonio - The new generation of goniophotometers

(Back to Top)

Fusion of industrial robotics and optics design

With the new, multifunctional goniophotometer robogonio a new era of goniophotometry has started. The high flexibility of the solid industrial robot combines several goniophotometertypes and light measurement applications into one single high-precision system. Luminous intensity distributions of luminaires in the far field (Eulumdat, IES, etc.), ray data of light sources in the near field, angle- dependent luminance information (glare etc.) or scanning measurement system, the goniophotometer robogonio does it all in one device! With the same precision conventional goniometers show - certified by the Technical Service for Testing of Lighting Devices "TÜV". "robogonio is completely state-of-the-art and due to its construction offers a nice finishing touch – extremely wide scope at and an extraordinary cost-performance ratio", so General Manager Juergen P. Weisshaar. The goniophotometer robogonio can serve as goniospectrometer as well, depending on the configuration. Besides the geometrical flexibility the use of the solid industrial robot is advantageous in respect of scalability, reliability and asset protection - worldwide.

Gonio'2pi-mini - The compact near-field goniophotometer

(Back to Top)

The fast-paced world of LEDs demands actual light source data for detailed optics simulations. Besides the datasheet parameters, ray data play an increasingly important role in optics simulations with respect to the small size and the narrow distance between the optics and the light source. opsira's gonio'2pi-mini is a compact system at a favourable price for measuring ray data mono- and polychromatically.

gonio'2pi-mini provides all possibilities its big brother gonio'2pi offers, however at a clearly smaller size. The dark box option enables the operation of gonio'2pi-mini outside of the dark lab. gonio'2pi-mini uses the same high-quality opsira detectors as the "big" goniometers of the gonio'2pi series and the robogonio series. The modular system of detector adapters makes a fast and precise change of the detector systems possible.
