A wavelength-tunable optical interference filter enables a small stitless monochromator to be made having a relative aperture which exceeds that of traditional slit monochromators having a comparable resolving power by 2–3 orders of magnitude. This

There are many varieties of light filters consisting of a reflecting prism and nonhomogeneous multilayers. In the present article we will consider two types of such light filters, a light filter that is selective with respect to wavelength and angle

Some results of two years of regular measurements of UV radiation at the earth's surface in Siberia (56.5o N, 85o E) are given. It is shown that the presence of snow cover increases the UV irradiation of the earth by scattered radiation by 9–15%. I

A study has been made of the influence of the geometric shape of a wavelength-tunable light filter on its following properties: 1) the tuning range of the wavelength selected by the light filter; 2) the ratio of the geometric cross sections of the in

The wavelength selected by a light filter is tuned by rotating the filter. The optimal positions are found for the rotational axis of a light filter used in different applications and meeting practical requirements.

The possibilities for expanding the range of tuning of the wavelength isolated by a tunable interference light filter, based on a combination of a nonuniform multilayer and a reflecting prism, are investigated. The degree of influence of the immersio

Tunable interference light filters [1–5] hold a special place among the multitude of light filters because they combine the advantages of light filters and dispersing prisms (diffraction gratings). Those light filters can monochromatize light in br

Correlation between total ozone content and scattered UV fluxes (A and B portions) measured in Tomsk (56.6N, 85E) during 1994 - 1998 has been investigated. It was shown that for the data corresponding to cloudless days the regression curve may be sat
