Measurements

Radiometry

The Laboratory instrumentation can provide:

• Sources Spectroradiometry and spectrophotometry (from 380 to 780 nm).
• Sources Radiometry between 200 and 2000 nm.
• Chromatic coordinates of luminous sources.
• Color temperature of sources and luminaires.

Characterisation of Materials

The Lab has a Perkin-Elmer Lambda 900 and a Perkin-Elmer Lambda 1050 double ray spectrophotometers with various accessories that allow to perform different kinds of measurements. Among these it is possible to obtain:

• Regular transmittance of transparent and semi-transparent samples
• Diffuse transmittance of transparent and semi-transparent samples
• Specular reflectance
• Diffuse reflectance

The measurements of diffuse reflectance or trasmittance can be realised with or without the regular component

Colorimetry

The Lab is equipped with instrumentation for the measurement of color and color difference for sources and materials.

With the Minolta CM-2002 colorimeter is possible to perform tests on opaque materials.  The Perkin-Elmer Lambda 900 spettrophotometer is employed for precise color determination both in transmission and in reflection. The Minolta CS-1000 spectroradiometer measures source color and color temperature.
The colorimetric data can be provided in one of the CIE reference systems (xyz, Lu'v', CIELAB, CIELUV).

Goniophotometry

The Lab is able to measure the radiation lobe of small sources (LED or optical fibers) or of the sources with dimensions up to about 30x30 cm with two differents measurement systems.  The angular range is included between -85 and +85 deg along a direction and within -90 and +90 in the other direction.

Luxmeters Calibration

The calibration procedure utilizes a certified luxmeter and a benchmark with 7,5 m of length.  We are able to supply to the customer, in addition to the experimental data, the formula for adjusting the measurement made by their own instrument.

Custom Measurements

The Lab is also available to examine measurement configurations with layouts and non standard procedures, in order to individuate and propose specific solutions
