The activities of the Photometry Laboratory of the NTUA concern:

• Scientific research (funded and non-funded).
• Quality assurance tests and measurements on lighting equipment, material and apparratuses.
• Conduction of seminars about lighting and photometry.
• Laboratory training of NTUA students.

The technical capabilities of the laboratory are the following:

• Measurement of luminous flux and luminous efficiency of every type of lamp (incadescent, fluorescent, metal hallide, etc.) with the use of photometric arrangements and standard lamps.

• Measurement of lamps life-time.

• Diagrams of polar distribution of luminous intensity.

• Measurement of efficiency of lighting fixtures.

• Water-tightness tests on lighting fixtures, under artificial rain.

• Measurement of glare characteristics of lighting fixtures.

• Measurement of reflectivity, absorbance and transmittance of several materials.

• Measurement of sun radiation (intensity and spectral composition).

• Luminance and illuminance measurements in road and tunnel lighting systems

• Illuminance measurements on lamps and lighting fixtures.

• Luminance measurements on surfaces, lamps and lighting fixtures.

• Measurements of electrical characteristics of ballasts by means of standard ballasts.

• Tests on lamp receptacles under controled conditions (voltage, temperature, humidity).

• Colorimetric measurements on lamps and lamp covers.

• Colorimetric measurements on industrial products (plastics, textiles, etc.).

• Calibration of instruments and apparratuses with the use of standard lamps.

• Calibration of photometers with the use of standard lamps.
