Goniophotometer
GMS2000
In this goniophotometer, the tested luminaire rotates in the prescribed burning position and around the vertical axle and a reflecting mirror rotates around the horizontal axle, meanwhile, a synchronous axle will rotate toward the opposite direction synchronously. The combined motion of the luminaire and mirror permit luminous measurement at the direction of any horizontal or vertical angle without tilting the luminaire, therefore, the luminous intensity will be not variation. The photometer head located at a fixed position of the limiting photomet- ric distance in front of the reflecting mirror to gather the light in each direction.

Photometers & Colorimeters
Instrument Systems Optische Messtechnik GmbH
A photometer is used to measure the photometric quantities of illuminance (lx), luminous intensity (cd), luminous flux (lm), and luminance (cd/m²). The integral method and the fast response time of silicon photodiodes means that photometers can achieve an outstanding measuring speed. They are therefore ideal for performing fast goniophotometric measurements. We take great care in the development and production of photometer heads and use innovative amplifier technologies.

Goniophotometer
A goniophotometer is a system to measure the luminous intensity of the source (or illuminance from the source at a given distance) in many different directions from the source. Compared with the sphere method, the goniophotometer method is theoretically free from errors due to differences in intensity distribution of the light source under test. It is applicable to acquire the luminous intensity distribution, luminous flux, spatial color distribution, and luminance distribution of lamps and luminaires.

Photometric Radiometric Transmitters
HD2021T6 / HD2021T7
The transmitters allow converting the photometric quantity “equivalent veiling luminance” – HD2021T7 – or a photometric quantity Luminance (cd/m2) – HD2021T6 – into a current (4…20 mA) or a voltage (0…10 V) signal according to the version chosen. If the acquisition station is far from the probe (>50m), it is necessary to use the current output version.The probe is used for the control of street lighting, in particular, the measurement of equivalent veiling luminance is essential to determine the threshold luminance at the entrance of the tunnels (UNI 11095:2011).

Photometric Probes for Illuminance
LPPHOT03… Series
The probe LPPHOT03 measures illuminance (lux), defined as the ratio between the luminous flux (lumen) passing through a surface and the surface area (m²). The spectral response curve of a photometric probe is similar to the human eye curve, known as standard photopic curve V(λ). The difference in spectral response between LPPHOT03 and the standard photopic curve V(λ) is calculated by means of the error f’1.

Integrating Sphere
The simpler way to measure the total luminous flux of lamps and luminaires is to use an integrating sphere photometer system. It is a device to perform spatial integration of flux optically, thus the total luminous flux can be measured with one fixed photometer head and measurement can be instant. An integrating sphere photometer is calibrated with a total luminous flux standard lamp. A test light source is measured by comparison to a standard lamp calibrated for total luminous flux.
