Aurora Nephelometer

In 2002 Ecotech developed the M9003, its first single wavelength integrating nephelometer. The unique feature of this instrument was the LED (Light Emitting Diode) light source (US Patent Pending). The lambertian distribution of the light source was achieved by adjusting the intensity of each of the 7 LEDs which would diffuse through a glass diffuser.

• The single wavelength light source (used in the Aurora 1000) now included 15 LEDS with improved electronic control of each LED
• A new 3 wavelength light source (used in the Aurora 3000) was designed which included 3 light source boards in the one housing.  This had 45 LED’s in total.

With rapid improvements in LED technology, it has been possible to obtain higher intensity outputs from smaller LED packages. As such, Ecotech released its opal glass light source in November 2008. This light source utilizes  an opal glass diffuser fitted in front of a small array of only 3 high intensity LEDs (per wavelength) to create a lambertian distribution Aurora 3000 nephelometer.
