  2. Prism compressor - Wikipedia

    en.wikipedia.org/wiki/Prism_compressor

    A prism compressor is an optical device used to shorten the duration of a positively chirped ultrashort laser pulse by giving different wavelength components a different time delay. It typically consists of two prisms and a mirror. Figure 1 shows the construction of such a compressor. Although the dispersion of the prism material causes ...

    en.wikipedia.org/wiki/Dichroic_prism

    Dichroic prism. A dichroic prism is a prism that splits light into two beams of differing wavelengths (colour). 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. They are usually constructed of one or more glass prisms with dichroic optical ...

    Automated lamellar keratoplasty ( ALK ), also known as keratomileusis in situ, is a non-laser lamellar refractive procedure used to correct high degree refractive errors. [1] This procedure can correct large amounts of myopia and hyperopia. However, the resultant change is not as predictable as with other procedures.
