Exempel på hur man kan använda DICHROIC i en mening

• 4th Century Rome: The Lycurgus Cup was crafted using dichroic glass which is a product of nanoengineering.
• An interference filter, dichroic filter, or thin-film filter is an optical filter that reflects some wavelengths (colors) of light and transmits others, with almost no absorption for all wavelengths of interest.
• In optics, a dichroic material is either one which causes visible light to be split up into distinct beams of different wavelengths (colours) (not to be confused with dispersion), or one in which light rays having different polarizations are absorbed by different amounts.
• With the crystals aligned, the sheet is dichroic: it tends to absorb light which is polarized parallel to the direction of crystal alignment but to transmit light which is polarized perpendicular to it.
• Herapathite, or iodoquinine sulfate, is a chemical compound whose crystals are dichroic and thus can be used for polarizing light.
• For observing the Sun, a much narrower band filter can be made from three parts: an "energy rejection filter" which is usually a piece of red glass that absorbs most of the unwanted wavelengths, a Fabry–Pérot etalon which transmits several wavelengths including one centred on the H-alpha emission line, and a "blocking filter" -a dichroic filter which transmits the H-alpha line while stopping those other wavelengths that passed through the etalon.
• To display images, LCD (liquid-crystal display) projectors typically send light from a metal-halide lamp through a prism or series of dichroic filters that separates light to three polysilicon panelsone each for the red, green and blue components of the video signal.
• GALEX used the first ever UV light dichroic beam-splitter flown in space to direct photons to the Near UV (175–280 nanometers) and Far UV (135–174 nanometers) microchannel plate detectors.
• A trichroic prism assembly combines two dichroic prisms to split an image into 3 colours, typically as red, green and blue of the RGB colour model.
• Hiltner that the recently detected polarization of starlight was due to dichroic extinction by interstellar dust grains aligned with the ambient magnetic field.
• A flat, tertiary, dichroic mirror was used to deflect the infrared part of the beam to the Nasmyth focus where it can be analyzed.
• Typical components of a fluorescence microscope are a light source (xenon arc lamp or mercury-vapor lamp are common; more advanced forms are high-power LEDs and lasers), the excitation filter, the dichroic mirror (or dichroic beamsplitter), and the emission filter (see figure below).
• A slot in the body of the unit for the insertion of metal gobos to change the pattern of the light in most cases is present, this slot can also hold a glass gobo, dichroic colour roundel or an effects unit such as a gobo rotator or iris.
• Before the pulse reaches the sample, some of the light is reflected by a dichroic mirror and gets detected by a photodiode that activates a delay generator controlling a gated optical intensifier (GOI) that sits in front of the CCD detector.
• Liquid-coupled projector CRTs have a curved-inwards face with coolant and (on the side that faces the CRT's electron gun) a screen that is curved towards the inside with a dichroic coating, the coating increases light output while the curvature conforms it to the curved back lens of the projector, reducing image halos.
• This light is collected by the same objective and, because it is red-shifted with respect to the excitation light it passes the dichroic mirror reaching a detector, typically a photomultiplier tube, an avalanche photodiode detector or a superconducting nanowire single-photon detector.
• The introduction of alkaline diuranates (like sodium diuranate) into glasses leads to yellow by transmission, green by reflection; moreover these glasses become dichroic and fluorescent under ultraviolet rays.
• The commercial title of "dichroic" can also display three or more colors (trichroic) and even iridescence in some cases.
• Ocean Optics has indicated that their patented dichroic filter CFA process (alternating thin films of ZnS and Cryolite) can be applied to spectroscopic CCDs.
• Because UVC can be deadly, a special dichroic filter glass (usually purple) is required that will filter out the UVC and UVB.
