CBG diffractive optical element is a reflecting Bragg grating with a period gradually varying along direction of beam propagation. This feature results in reflection of different wavelengths from different holographically recorded planes inside the grating . OptiGrate products based on CBG elements are;Optical axis gratings (OAGs) are gratings of optical axis of a birefringent material. In OAGs, the birefringence of the material is constant, while the direction of optical axis is periodically modulated in a fixed direction.;Mbuzi means goat, and this beautiful device is used to grind coconuts in Tanzania . Made from one piece of wood. More info in the video!;Gratings are basically periodic layouts that may contain chirp or apodization. The wave inside the grating may be complex: Scattered field, transmittedFigure 2: Silver Grating .

What is an optical grating ?Quora
In optics , a diffraction grating is an optical component with a periodic structure that splits and diffracts light into several beams travelling in different directions. The emerging coloration is a form of structure colouration. The directions of these beams depend on the spacing of the grating and the wavelength;Grating writing in structured optical fibres and their properties and applications are reviewed. To date, most gratings have been written in aAlthough grating writing has been demonstrated in a range of structured optical fibres, the rotational variance of these fibres, however, leads to variations in the;The diffraction grating of a spectrometer determines the wavelength range and partially determines the optical resolution that the spectrometer will achieve.Thus, for spectroscopic applications (such as UV spectroscopy) where the detector response is poorer and the optics are suffering more loss;Tanzania Measurement & Analysis Instruments Optical Instruments Companies in Tanzania .
