Back-Thinned L3Vision CCDs From e2v Set Unprecedented Standards In Low Light Sensitivity

		The back-illuminated CCD60 was the first CCD to offer sensitivity close to the theoretical maximum for a silicon imaging sensor, with quantum efficiency greater than 90% and read noise less than one electron. The back-thinned CCD60 provides a 128×128 pixel format at frame rates up to 1kHz and extends the scope of CCD sensor applications to include confocal microscopy, single molecule imaging, photon counting and adaptive optics. Complementing the back-thinned CCD60 in the L3Vision™ product portfolio is the recently launched back-illuminated CCD97. Delivered in a 512×512 frame transfer format, this new 30fps frame rate imager is ideal for high resolution scientific imaging at low light levels. The sensor uses a novel electron multiplication output amplifier circuit that can operate with read noise of less than one photoelectron at pixel rates in excess of 11 MHz.
Cliff Weatherup, L3Vision™ Programme Manager at e2v comments, "L3Vision is a breakthrough technology, extending the boundaries of CCD sensitivity and enabling photon counting performance in an imaging sensor. These improvements in high speed, low light imaging open a new window of opportunity and we look forward to providing solutions for customer requirements."
