Teledyne-e2v designs and manufactures a wide range of sensors for space and astronomy applications. This includes high performance CCDs for x-ray, visible and near-IR wavelengths. In this paper we illustrate the maturity of CMOS capability for these applications; examples are presented together with performance data. The majority of Teledyne-e2v sensors for these applications are back-thinned for highest spectral response and designed for very low read-out noise; the combination delivers high signal to noise ratio in association with a variety of formats and package designs. The growing Teledyne-e2v capability in delivery of subsystems and cryogenic cameras is illustrated-including the 1.2 Giga-pixel J-PAS camera system.

Teledyne e2v has a well-established heritage of designing and supplying high performance sensors for professional astronomy. These CCD and CMOS image sensors are back-thinned for maximum quantum efficiency, designed for lowest read-noise, and optimised for high frame rate use. CCDs are appropriate cost-effective solutions for modest formats (e.g. 240 X 240 pixels) but CMOS architectures are required for larger formats at high frame rates. We describe key elements of a major proposed sensor design for the E-ELT; this "LVSM" detector has 800 X 800 pixels in a design that is optimised for ELT use. High rate CMOS sensors use multiple parallel ADC blocks and deliver very low pixel noise coupled with very low noise ADC circuits. These sensors provide high sensitivity at low signal levels for natural and laser guide star applications. We present examples of sensor designs ranging from 80X80 to 1600X1600 pixels in simple and more complex Peltiercooled packages. Sensor performance considerations such as intra-pixel response, cross-talk, uniformity, data paths, and others are discussed.
