... The near-UV prism (NUVOP) transmits only above 1600 with a wavelength dispersion / around 100 at 2500 . ... The wavelengths determined from objective prism spectra using these dispersion curves should have a / error of <1% for f /96 spectra. ... 4000 . ... Overall, photometry of objective prism spectra should have errors of about 10% or less for wavelengths below 4000 for NUVOP spectra and below 2500 for FUVOP spectra, provided that the position of the undispersed target is known to within a pixel. ...

. Light bounces differently through binoculars according to the juxtaposition of the prisms. Porro-prism binoculars are generally preferred for astronomical use because they provide total internal reflection. Rick Johnson

... The XMM Optical Monitor can produce data in two modes: Imaging and Fast (timing). The omgchain package reduces the OM Imaging mode data taken with either the UV or Optical grism filters (prism filters with diffraction gratings on the back which facilitate low-resolution spectroscopy). There are two filter positions of the filter wheel in front of the OM detector which are occupied by grisms (hereafter called grism-filters), one designed for the UV spectral range and another for the visual. ...

Halo around the Moon. Halo arises when the light beams refracted on the high clouds icy chips ina form of a six side prism. As a result we see a small halo circle with a 22°-radius. The big circle is formed by the beams paased through the side edge and the base of prismochips. Its radius is equal to 46° (nearly). The big circle is observed rarely and is shining weaker but it is easier to observe it near the Sun, if comparing with the small halo invisible in the bright Sun light. ...
