Reflectance data for Acktar black light-absorbing coatings have been incorporated into the libraries of the major optics simulation software packages Zemax and TracePro and soon will be incorporated into ASAP and FRED. Kiryat- Gat, Israel (PRWEB) December 10, 2013 A central application of these simulation packages is in design to reduce the negative effects of stray light from bright objects outside the field-of-view and from thermal emission within the system itself. Stray light which is...

What Is The 'Golden Spider'
2012-08-24 09:47:51

What looks like a giant golden spider weaving a web of cables and cords, is actually ground support equipment, including the Optical Telescope Simulator (OSIM), for the James Webb Space Telescope. OSIM's job is to generate a beam of light just like the one that the real telescope optics will feed into the actual flight instruments. Because the real flight instruments will be used to test the real flight telescope, their alignment and performance first have to be verified by using the OSIM....

Image 1 - NASA Material Absorbs Light Across Multiple Wavelength Bands
2011-11-09 04:23:46

NASA engineers have produced a material that absorbs on average more than 99 percent of the ultraviolet, visible, infrared, and far-infrared light that hits it -- a development that promises to open new frontiers in space technology. The team of engineers at NASA's Goddard Space Flight Center in Greenbelt, Md., reported their findings recently at the SPIE Optics and Photonics conference, the largest interdisciplinary technical meeting in this discipline. The team has since reconfirmed the...

Measurements of the intensity of light at different wavelengths can be made more accurately now, thanks to a new, simple method for correcting common instrument errors. The new method, developed by researchers at the National Institute of Standards and Technology (NIST), will benefit fields such as color measurement, lighting development, remote sensing, biotechnology and astronomy. The NIST method improves the measurement accuracy of spectrometers, devices that measure optical radiation at...

Word of the Day
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
