while the incident angle on the normal diffraction grating stays the same. Each set of fringes stays in the same position but the relative intensities of the colours in each fringe change. The ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

The absorption grating provided moiré fringes of 32% visibility ... The slits are essential for separating the diffraction orders of the phase gratings in a far-field interferometer.

It’s the same effect you see on the bottom of a CD! You can 3D print a functional diffraction grating, too, with the right techniques, as it turns out! The average 3D printer can’t recreate ...

Consider a transparent phase grating, that is a diffraction grating that transmits ... appropriate magnification shows that the original and regenerated caustics (and associated diffraction fringes ...

The diffraction grating of a spectrometer partially determines the optical resolution that can be achieved by the spectrometer and also determines the wavelength range. Selecting the correct grating ...

The front end of the instrument is just a handheld diffraction-grating spectroscope, of the kind used in physics classrooms to demonstrate the spectral characteristics of different light sources.

Rotating the diffraction grating controls which wavelengths of light reach another mirror, which in turn focuses these wavelengths onto a photodetector, such as a charge-coupled device.

McPherson's SXR spectrometer, Model 251MX, is now available with improved efficiency over a wider range. A new diffraction grating is available! The new Gold coated diffraction grating is ideal for ...

The Dittoscope is essentially a huge diffraction grating: a flat surface that is grooved in a regular pattern. (A cross-section would look like a series of regular waves.) Astronomers have used ...
