When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording ...

Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of grooves ...

Diffraction gratings are curious things. Score a series of equally spaced tiny lines in a surface, and it will cause reflected or transmitted light to bend and separate into its component wavelengths.

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 ...

The aluminumcoated gratings are for use in spectrometers, spectrophotometers, and monochromators. Ion-beam etching creates the sawtooth design common to ruled gratings and eliminates the need for ...

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 ...

Using a novel method, beams of laser light can be deflected using air alone. An invisible grating made only of air is not only immune to damage from the laser light, but it also preserves the original ...
