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.

Microwave Wideband Synthesizer w/ Integrated VCO
ADF5356
-
The ADF5356 allows implementation of fractional-N or integer-N phase-locked loop (PLL) frequency synthesizers when used with an external loop filter and an external reference frequency. The wideband microwave VCO design permits frequency operation from 6.8 GHz to 13.6 GHz at one radio frequency (RF) output. A series of frequency dividers at another frequency output permits operation from 53.125 MHz to 6800 MHz. The ADF5356 has an integrated VCO with a fundamental output frequency ranging from 3400 MHz to 6800 MHz. In addition, the VCO frequency is connected to divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allow the user to generate RF output frequencies as low as 53.125 MHz. For applications that require isolation, the RF output stage can be muted. The mute function is both pin- and software-controllable.

Load Testing vs. Stress Testing
-
A load test is a planned test to perform a specified number of requests to a system in order to test the functionality of the system under specific levels of simultaneous requests. A load test ensures that a web system is capable of handling an expected volume of traffic, and therefore is sometimes referred to as volume testing. The goal of a load test is to prove that a system can handle the expected volume with minimal to acceptable performance degradation. The threshold of acceptable performance degradation must be defined by the testers as some value considered acceptable to the end user so that users will not bounce from the site.

Counters, Timers, And Ratemeters
-
ORTEC offers the broadest range of nuclear counters, timers, rate meters and multichannel scalers. Counters simply count the number of input pulses received during the counting period. Timers count pulses generated by an internal or external clock and are used to measure elapsed time, or to establish the length of the counting period. Rate meters provide a readout of the pulse count rate. Multichannel scalers count the number of events that occur during a specified time interval, referred to as the dwell time, resulting in a time-histogram of counts. “Standalone” and programmable computer controlled versions are available.

Viscometers
-
A viscometer, viscosity meter or rheometer is a measuring instrument used to determine a fluid's internal flow resistance or viscosity. The term viscosity typically refers to shear viscosity, i.e., how a material reacts to being sheared. Rotational viscometers with rotating spindles or rotors, also known as "cup and bob" or Searle viscometers, are the most common tools used to measure the shear viscosity of fluids. However, a fluid's viscosity also may be measured on the basis of stretching. The technical term to refer to this is extensional viscosity.A viscometer is frequently used in laboratories, but it also has practical applications in factories and other industrial environments. A viscometer can be an important component in process and quality control. Companies can save money by placing a viscometer in a production line and making fluid viscosity measurements in real time.PCE Instruments offers a variety of handheld, portable, benchtop and in-process, real-time viscometer products that measure the absolute / dynamic (shear) and kinematic viscosity of fluids. Handheld or portable viscosity meter devices allow users to take simple, single-point measurements in the field and in the lab. Benchtop or stationary viscometer devices are complex rheological measuring systems that allow for a more detailed examination of liquid samples.
