Menlo systems – View into the universe

gil — Wed, 07 Oct 2020 08:52:28 +0000

Italian researchers synchronized two remote radio telescopes by transferring time signals, derived from Italy’s atomic clocks, to their individual local clocks.

The up- and down-conversion of microwave and optical signals in use was carried out by two FC1500 optical frequency combs and a PMWG-1500 ultrastable microwave generator system.

This technique will significantly enhance the precision of observations of radio emission sources in the Universe.

Why do you need an optical clock?

Avantes – LED

roshussl_admin — Thu, 11 Jun 2020 07:09:10 +0000

The measurement of LEDs presents unique application requirements for which Avantes has the appropriate instrumentation and applications experience to assist our customers in configuring a system. Avantes’ many years of working with LED application has prompted us to develop a variety of system configurations that meets most LED metrology requirements

Light Emitting Diodes can be measured in a wide variety of colors and brightness. Accurate measurement of the LEDs therefore is essential. This can be done in two ways: photometry and radiometry. We have two specific LED measurement set ups (bundles) created, you can find them HERE

Photometry relates to visible radiation alone, just as the response of the human eye. Radiometry goes beyond these limitations. In both photometry and radiometry, the LED can be characterized in emitted power or in intensity. Emitted power is all the power (flux) emitted from the LED in lumens or Watts, collected and measured without regards to the direction of the flux. The intensity is the ratio of the flux, leaving the source and propagating in the element of solid angle containing the given direction, and is expressed in candelas.

For basic measurements of photopic parameters and irradiance (excluding flux) a system is typically configured with the AvaSpec-ULS2048-USB2-FCPC spectrometers, a 25 or 50 µm slit and 300 line/mm grating covering the range from 360-1100 nm and provides 1.4 -2.4 nm full width half maximum (FWHM) resolution. A 2 meter fiber-optic cable (FC-UV200-2-FC-SMA) is mated to the instrument and terminated in a cosine function diffuser (CC-UV/VIS/NIR) which has 3.9 mm diameter surface area. The entire system is irradiance calibrated with an NIST source over the specified wavelength range for spectral irradiance (µW/cm2/nm). This calibrated system can be operated using Avantes proprietary AvaSoft-IRRAD software which provides the following parameters: X, Y, Z, x, y, z, u, v, CRI, Color Temperature, Dominant Wavelength, Complementary Dominant Wavelength, FWHM, Centroid, Peak Wavelength & Purity. Additionally raw data in scope mode is displayed, as well as the X-Y chroma-ticity diagram. Optionally, the system can be configured with longer fiber lengths and the AvaTripod to hold the diffuser in place during measurement. The system can be controlled via Avantes dynamic linking library (DLL) interface through LabView, C#, C++ and a number of other programming environments.

Avantes also offers two system configurations to enable the CIE Average LED Intensity (ALI) measurements which are specified in the CIE Publication No. 127.

Labsphere – Coatings & Materials

roshussl_admin — Thu, 11 Jun 2020 07:06:17 +0000

Diffuse reflectance is used to calibrate spectrophotometer and imagers, scatter light, control light levels and make light insensitive to directionality. Labsphere makes some of the best diffuse reflectance materials on earth and in space. Here are just a few applications of our renowned materials

Awaken the Force for Your Space Applications

Labsphere’s Space-Grade Spectralon® Reflectance Material has gained wide acceptance as a reflecting diffuse material for terrestrial remote sensing applications for both field and laboratory applications. Space-Grade Spectralon combines high reflectance with an extremely Lambertian reflectance profile.

Space-Grade Spectralon has undergone extensive testing for UV exposure, Proton bombardment, atomic oxygen exposure, a-Lyman radiation, outgassing and static charge testing by national laboratories, such as Jet Propulsion Laboratory, Goddard Space Flight Center, TRW, and CSEM. This testing has led to the development of a stringent manufacturing process that eliminates potential contaminants which lead to UV degradation.

Lightweight and Durable Diffuse Reflectance Targets

Repeatable, durable targets to characterize and calibrate LIDAR sensors over a broad range of ambient conditions. Highly Durable, Lightweight Targets up to 125 x 245 cm.

No other options compare
• Lightweight • Tailorable • Uniform • Durable • Easy to Clean

Applications
• Time of Flight • Ground Truth • Imager Calibration • Sensor/Source Compensation • LIDAR

Why grey painted cards, fabrics and paper may put you at a disadvantage…

For imaging applications your grey target solution must work for a wide variety of lighting environments and still maintain its appearance. Most importantly it has to have uniform spectral response. It also must be thermally and physically durable, UV light stable, thermally color stable, no gloss, no polarization and no fluorescence. If your grey target solutions do not meet these requirements, you need Permaflect.
