“…This plane is an intermediate image plane of the microscope, to which the field number of the eyepiece is applied. Thus, we used FN=0.594 mm to calculate the angular field of view, or aperture, at the entrance of the LiL-CPI according to the equations in [19].…”

“…The AOTF-based add-on module 1 is inserted between the microscope body and the trinocular head. It consists of a beam-splitter, an optical coupling system, the AOTF, an imaging objective and a monochrome camera [9]. The device is designed to allow simultaneous visual observation of the Image Processing and Earth Remote Sensing A B Burlakov, A S Machikhin, D D Khokhlov, V I Kuzmin, A F Gadzaov, D L Tytik, S A Busev, V E Kasatkin and, L A Sleptsova specimen, color image registration and acquisition of spectral image series necessary for the measurement of the absorption spectra distribution.…”

“…However, the disadvantages of filter wheels included speed, size, lack of customization, and small number of bands. An alternative to mechanical filter wheels was electronic tunable filters, which were mainly acoustooptical tunable filters (AOTF), 88 90 liquid crystal tunable filters (LCTF), 62 , 63 , 91 93 or Fabry–Perot interferometers (FPI). There existed other mechanisms for manufacturing tunable filters, such as surface plasmon coupled tunable filters; 94 however, three types described earlier are still the most popular.…”

“…Both AOTF and LCTF require large external power and large optical pathway, which makes them unsuitable candidates for ultracompact systems 94 . While the size of the filters in AOTF and LCTF themselves is compact and lightweight (often <1 kg), 88 , 89 , 118 , 145 , 146 it is the weight of filter driver that adds up to the weight of these devices.
