The i-trometer™ features a Back-thinned CCD Array with a pixel format of 2048 x 1 element @ 14um x 14um with effective (Active) pixels > 2000. Each pixel represents a portion of the spectrum and as the incident light strikes the back of this thinned piece of substrate, individual pixels across the CCD are then translated by the electronics and their intensity displayed using our software, BWSpec™. By using this Back-thinned method, the Quantum Efficiency (QE) is increased by > 30% compared to most Front Illuminated Linear CCD arrays. This detector also has very low read out noise allowing for low-light level detection (long integration times) for achieving a wide dynamic range.
