1. Introduction
Optical Filters . ... In addition to the above complement of broad and narrow-band filters, WFPC2 features a set of three specialized quadrant (quad or Q) filters in which each quadrant corresponds to a facet of the pyramid, and therefore to a distinct camera relay. ... In Table 3.1 and Table 3.2 , each of the type "A" filters is equivalent to inserting 5 mm of quartz in terms of optical path length, with compensation for wavelength such that focus is maintained on the CCDs. ...

2. Descrizione tecnica NICS
... All the optical elements are mounted in a cryostat aimed at keeping components at a temperature of about 80 K. The focal plane masks (field stops or slits) are mounted on a wheel. ... The collimator is an achromatic doublet lens, which images the entrance pupil of the TNG and provides an almost parallel beam (F-number about 2000) at the pupil plane, where Lyot stops can be placed. Right after the pupil plane, two close wheels mount filters and grisms. ...

4. Optical static Fourier spectrometer
Static Fourier spectrometers are often used for spectral measurements of the ionosphere emissions. There are two main advantages of Fourier spectrometers (FS) - large geometric factor and high spectral resolution; these parameters are two orders better than for grating spectral instruments. ... In scanning Fourier spectrometer optical and electric modulation of signal is used to avoid this problem, for static Fourier spectrometer there are no such ways. ...

18. Grism data
... 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. ...
