Custom Grating Sizes Available HANDLING OF GRATINGS The surface of a diffraction grating can be easily damaged by fingerprints, aerosols, moisture, or the slightest contact with any abrasive material. Gratings should only be handled when necessary and always held by the sides.;Holographix works closely with our customers to assist them in the development of custom grating-based solutions from concept to production. We have successfully advanced our design and manufacturing processes allowing us to produce custom surface-relief transmission gratings that consistently meet or exceed the performance of volume phase holographic (VPH) gratings, but at a fraction of the cost!;A label-free optical biosensor is described that employs a silicon-based high-contrast grating (HCG) resonator with a spectral linewidth of ~500 pm that is sensitive to ligand-induced changes in ;VPH gratings are created by imaging a periodic structure of high and low index of refraction into dichromated gelatin hermetically sealed between two optical windows. This process allows us to generate very high quality diffraction gratings in volumes of 1 to 1000 pieces or more.;The tool calculates grating performance using a scalar theory of diffraction 1. Reference papers used in the development of this calculator can be found in the Bibliography at the end of this note. Grating Principles. An optical grating acts as a wavelength dispersive element by diffracting or refracting light from a periodic structure.;A label-free optical biosensor is described that employs a silicon-based high-contrast grating (HCG) resonator with a spectral linewidth of ~500 pm that is sensitive to ligand-induced changes in
