New spectroradiometers

Distributor Pro-Lite Technologies has introduced two new spectroradiometer products from Labsphere and Ocean Optics.

The TOCS series of integrating sphere spectroradiometers, produced by Labsphere, provide complete thermal, optical and electrical characterisation of LEDs and LED modules in accordance with the IESNA standard methods LM-79 and LM-80. TOCS systems are based on a 20, 40, 65 or 76-inch interior access sphere with provision for both 2π forward and 4π total flux measurements.

The TOCS systems comprise of an interior access integrating sphere coupled to a fast CCD spectrometer. The device under test is held on a temperature controlled electrical socket which is placed at the external source port on the sphere for 2π flux measurements. The systems includes a choice of calibration source (external 2π, internal 2π or 4π), auxiliary lamp for correction of sample absorption and power supplies for the calibration and auxiliary lamps. The systems are controlled by a Windows PC using Labsphere's menu driven TOCS application software.

Also added to Pro-Lite's range is the USB2000+IRRAD modular spectroradiometer system based upon the USB2000+ spectrometer produced by Ocean Optics. This system has the flexibility to measure spectral radiant flux, intensity and irradiance as well as derived photometric (illuminance, luminous intensity) and colorimetric (chromaticity, colour temperature and colour rendering) properties. Using interchangeable collection optics and integrating spheres, users can configure the system to measure solar irradiance or the output of lamps, LEDs, optical fibres, lasers, or any other type of light source.
