About This Product
■Summary
As the light travels, it causes a diffraction phenomenon that hits the edges of obstacles and is broken down into spectra, resulting in the appearance of beautiful rainbow colors from white light. Can be used as science teaching materials, spectrometer production, and art teaching materials at school. This product, which has a film thickness of only 76 μm, is used to split white light into a rainbow-colored spectrum and as a monochromatic beam splitter such as a laser.It is inexpensive and can be easily used for educational and experimental purposes. Available.
There are two types of linear films, one with a grating frequency of 1,000 lines/mm and one with a grating frequency of 500 lines/mm, and both have a holographic diffraction grating type SIN wave shape in cross-section, so compared to the blazed type. It has the advantage of generating less stray light. As the grating frequency increases, the obtained fractional angle also increases.
Therefore, a film with a grating frequency of 1,000 lines/mm disperses the spectrum over a wider range than a film with a grating frequency of 500 lines/mm, and the higher the grating frequency (number of lines), the higher the resolution, and the more clearly the absorption and emission spectra can be seen. It will look like this. When you are looking for the effect of viewing the spectrum using a kaleidoscope or spectroscope, the more lights you use, the better the effect you can expect. Conversely, a 500 lines/mm film is used when higher diffraction orders are required than can be obtained with a 1,000 lines/mm film.
Cross-type (530 lines/mm) film has a spectrum that looks like a cross, creating a more fantastical effect than a straight line, and may be the best material for a kaleidoscope.
