​Key Advantages: 

  • ​Bandgap engineered 

  • Tuneable wavelength 

  • Substrate removed, deep depleted and fully depleted (low dark current) MCT 

  • Simultaneous UV, visible, IR light detection 

  • On-FPA signal processing 

  • In house HgCdTe growth

With in-house capabilities in the US and UK, Teledyne is able to meet any detector requirement from Photodiodes, to high rate production of IR FPAs, including large custom FPAs for the most demanding applications.

  • Detector through to camera level and standard through to custom solutions

  • Offering a range of application tuned solutions from Visible to VLWIR 

  • Custom solutions: CMOS, ROIC and diode packages 

  • Full packaging design and test capability 

  • A range of Cryogenic and Thermo Electric Cooling (TEC) methods 

  • High Operating Temperature (HOT) technology 

  • Low SWaP (Size, Weight and Power consumption)  

  • Enabling power efficient systems 

  • Reduction in cooler/dewar capacity requirement 

  • Reduced maintenance and total cost of ownership 

All of Teledyne’s cooled IR FPAs are hybrid CMOS image sensors which are made by hybridizing a detector array to a readout integrated circuit (ROIC) that is optimized for the imaging application. Teledyne’s hybrid CMOS ROICs are optimized for two main applications:​

  1. ​HAWAII analog ROIC

    Designed for low light level, long exposures of astronomy

    Very low power. For example, the H2RGs operate on the James Webb Space Telescope with 0.5 mW of power (not a typo, only 1/2000th of a watt!)​

  2. GeoSnap digital ROIC

    ​Designed for higher light level, fast frame rate applications of Earth observation and defense applications​

​The James Webb Space Telescope

Uses 15 Teledyne H2RG 2048×2048 pixel infrared detectors

Teledyne supplied 63 million IR pixels for three of JWST’s instruments: Near Infrared Camera (NIRCam), Near Infrared Spectrograph (NIRSpec), and the Fine Guidance Sensor (FGS)

​Euclid Space Telescope

Uses 16 Teledyne H2RG 2048×2048 pixel infrared detectors for the Near Infrared Spectrometer and Photometer (NISP), which u​ses a 4×4 matrix of 2040×2040, 18 µm pixel detectors. Also includes 36 Teledyne CCD273-84 visible sensors in a 6x6 mosaic of 4096×4132m, 12 µm​ pixel for a total of about 600 megapixels.​

​Plato (PLAnetary Transits and Oscillations of stars)

Uses 26 cameras to find and study terrestrial exoplanets in orbits in the habitable zones of Sun-like stars. Each of the 26 cameras uses four Teledyne visible CCDs; each CCD has 4510x4510 pixels (18 µm pitch). Each camera has more than 81 million pixels, and there are a total of more than 2 billion CCD pixels in the 26 cameras of the PLATO mission.

​Nancy Grace Roman Space Telescope

The infrared sensor chip assembly (SCA) developed for Roman is the H4RG-10, 4,096×​4,096 pixels, and each pixel is 10 by 10 microns in size. (A human hair is about 100 microns wide.) 18 H4RG-10 SCAs are in the focal plane mosaic of Roman, totalling over 300 million pixels. This is by far the largest infrared focal plane ever made, for space or ground-based facilities.​ In addition to the infrared arrays, Teledyne also produced three visible light CCD311-20 detectors that will be used in the coronograph instrument of the Roman Space Telescope.
