OL 754 spectroradiometer (upgraded from OL 752) from Optronic Laboratories, Inc. is able to measure the spectrum of different light sources from 250 to 800 nm or from 200 to 400 nm depending on the calibration. The system saves the measured values in an ASCII-file on a laptop computer from where it is easy to calculate various lighting quantities directly after the measurement or on a later stage.
The Lighting Laboratory has three different optics heads to be used with the spectroradiometer:
- an integrating sphere reseptor which can be rotated 360 degrees
- an attachment piece for the integrating sphere to be able to measure the luminous flux of through-hole LEDs with a diameter between 3 to 10 mm (see picture above)
- an optics head for measuring the luminous intensity of through-hole LEDs (diameter 3 to 10 mm)
