Holographic and Ruled diffraction gratings are available from Optometrics for use in high-level spectroscopy, alongside our Echelle, Filtered and Transmission gratings. One of the few gratings ...

I HAVE recently described 1 a method of ruling diffraction gratings on cylinders by a method which gives results substantially free from the periodic errors otherwise difficult to avoid; and by ...

Visual demonstration of the performance of the diffraction grating. The zeroth order transmission refers to light that goes straight through the grating without undergoing diffraction (which should be ...

A variety of ultrathin nanomechanical diffraction gratings that have been fashioned from the “wonder material” graphene have been created by an international team of researchers. The team wanted to ...

Inprentus, a Champaign, Illinois, company filed paperwork with the SEC on Friday that it had completed a raise of more than $1 million. Inprentus makes blazed diffraction gratings used at synchrotrons ...

When ordering a plane grating, please use the following example format: P 1200 W x H x Thk 700-900 nm (TM+TE)/2 (-1) constant deviation angle 10° Groove densities: Spectrogon manufactures 600 ...

FROM an article in No. 2, vol. xxii., of the Astro-physical Journal, we learn that Mr. R. J. Wallace, of the Yerkes Observatory, has attained great perfection in the production of replicas from plane ...

Synergy 4 Combines the Features of Filter- and Monochromator-based Systems As assays and detection technologies have advanced in microplate format, space-saving and user-friendly multimode (or ...

The spectrum of laser technologies available to hackers has gradually widened from basic gas lasers through CO2 tubes, diode lasers, and now fiber lasers. One of the newer entries is the MOPA laser, ...

— A silicon device with thousands of slats of tiny mirrors lined up to resemble a jalousie window could speed the efficiency of NASA’s next-generation space telescope, the Constellation-X Observatory, ...
