Astronomy Solutions
For more than 40 years, Thales has delivered high accuracy optics for ground-based Astronomy all around the world. These optics range from single, but challenging, unmounted optical components up to fully integrated opto-mechanical systems. Our design heritage and past experience in this field cover the design, manufacture and AIT activities of many optics and sub-assemblies used in Telescope instrumentation, such as focal plane assemblies as well as the direct production of telescope mirrors themselves. Several major achievements of Thales ground-based Astronomy products were the Optical wide field corrector for the Dark Energy Survey (lien), the Reference Body for future Deformable Secondary Mirror of the VLT (lien) and different challenging spectrograph optics (Collimator and Cameras) for different Observatories (lien). One advantage Thales has with this activity is that most part of the manufacturing steps involved (i.e. opto-mechanical design, milling/grinding, lightening, polishing and coating) are directly under our control in our own facility. Our current capabilities for the production of optics for ground-based Astronomy are from a few centimeters size up to 2 meters. Thanks to the continuous efforts in R& D and investments into new production machines, Thales is now ready for future industrial challenges including the optical production of some key elements of the E-ELT, GMT and TMT programs.

Electron Multiplication (EM) Standard Image Sensors
EM (Electron Multiplication) is a technology that uses on-chip gain in the charge domain to effectively eliminate read noise from an image sensor. This enables advanced ultra-low light applications that require extreme sensitivity at fast frame rates. Examples include life science applications such as single molecule detection, super resolution microscopy and spinning disk confocal microscopy along with physical science applications such as nanotechnology imaging, Bose Einstein condensates and soft X-ray spectroscopy, and astronomy applications such as adaptive optics and lucky imaging. The inclusion of an additional conventional output allows further flexibility for applications such as true 24 hour surveillance.

Far Infrared Systems
Far-Infrared and terahertz (THz) radiation is the spectral region at the long wavelength end of the infrared and the short end of the microwave region, also known as the sub-millimeter wavelength spectral region. Recently, there has been an explosion of interest in THz applications as the radiation generated can penetrate various materials. THz light is commonly used in materials science, security, pharmaceutical com- pound analysis, biomedical imaging, superconducting materials, astronomy, and particle physics research.

Frequency Multiplier
SMZ
R&S®SMZ frequency multipliers combine easy handling and precise output levels in the frequency range from 50 GHz to 170 GHz. They can be used in diverse applications, e.g. in the automotive sector with distance radars, in astronomy with sophisticated telescopes and in radar interferometry for analyzing the earth’s surface.The frequency multipliers are available in the R&S®SMZ75 (from 50 GHz to 75 GHz), R&S®SMZ90 (from 60 GHz to 90 GHz), R&S®SMZ110 (from 75 GHz to 110 GHz) and R&S®SMZ170 (from 110 GHz to 170 GHz) models. An optional attenuator (available for R&S®SMZ75, R&S®SMZ90 and R&S®SMZ110) can be integrated in the same housing as the frequency multiplier, simplifying handling. The R&S®SMZ can be controlled via USB.

Low-Noise DC Bias
Imaging devices, such as CCDs, IR FPAs, and CMOS image sensors, require DC bias with very low electrical noise to prevent contamination of the image. Image quality can also be enhanced by carefully tuning each bias voltage to extract the maximum signal/noise ratio out of an array. Pulse Instruments has decades of experience providing DC bias supplies with the flexibility required tocharacterize and test a variety of devices while maintaining the noise immunity required for satellite and astronomy applications.
