Ultrablack Coatings Achieve Broadband Absorption for Precision Optics
SHANGHAI, March 21, 2024 — A broadband, ultrablack film from the University of Shanghai for Science and Technology and the Chinese Academy of Sciences could enhance the performance of telescopes among other applications in space exploration and precision optics. In tests, the film achieved an average absorption as high as 99.4%, within a wavelength range of 400 to 1000 nm. Optical devices that require ultrablack coating for stray light suppression often exhibit significant curvature and intricate shapes,
Ophir-Spiricon Opens New Cleanroom
LOGAN, Utah, June 28, 2011 — Ophir-Spiricon, a member of the precision laser measurement equipment provider Ophir Photonics Group, has opened a cleanroom at its new facility in Logan. The 840-sq-ft cleanroom is used for manufacturing the solid-state, pyroelectric detector...
High-Throughput Optical Coating
Aug 1, 2008 — Sputtering processes for thin-film deposition are naturally energetic and generally do not require additional heat input to generate good morphology. As a result, sputtering is a suitable deposition technique for heat-sensitive substrates such as...
Folded Spectrometer Offers Range, Resolution and Speed
Mar 1, 2006 — Spectrometer design usually involves compromises among acquisition time, spectral resolution and wavelength range. A spectrometer that was developed at Fudan University in Shanghai, China, using a two-dimensional back-thinned silicon CCD has...
Industrial MicroscopyGets Down to Work
Aug 1, 2004 — It's a three-dimensional world for industrial microscopy these days, whether it is used to help monitor thin-film deposition processes or to inspect bumps on a circuit board. Regardless of the technique, building the 3-D image usually involves...
