Abstract: PROBLEM TO BE SOLVED: To constitute an illuminating device for a DUV microscope so that it can supply a DUV wavelength band having the maximum transmittance and a small half value width.
SOLUTION: The illuminating device for the DUV microscope (1) is provided with an illuminating beam path (6) emitted from a DUV light source (5), and a collector (7) and a reflection filter system (9) are arranged on the illuminating beam path, the DUV wavelength band is formed by the reflection filter system, and the reflection filter system is constituted of four reflection filters (8), and also, a transmission filter is not installed between the reflection filters. The illumination beam path (6) is separately reflected by each reflection filter at the same reflection angle α, and the illumination beam path (6) coaxially extends before and behind the reflection filter system (9). According to this invention, incident angle α≤30° is established, the DUV wavelength band is provided with the half value width of 20nm maximum and a peak having a peak value S of ≥90% of the incident light intensity. A DUV objective lens for the DUV microscope (1) can be very satisfactorily corrected by the attained very narrow half value width of the DUV wavelength band.

Abstract: PROBLEM TO BE SOLVED: To enable an illuminator for a DUV microscope to supply a DUV wavelength band having maximum transmissivity and small half value width. SOLUTION: This illuminator for the DUV microscope 1 is equipped with an illumination beam path 6 emitted from a DUV light source 5, and a collector 7 and a reflection filter system 9 are arranged in the beam path 6. The system 9 forms the DUV wavelength band and is composed of four reflection filters 8. The beam path 6 is reflected by the filter 8 by the same reflection angle α, and the beam path 6 is coaxially extended ahead and astern of the system 9. Thus, an incident angle α =90% of the intensity of the light made incident. The DUV objective lens of the DUV microscope 1 is very excellently corrected according to the half value width of the very small attained DUV wavelength band.

Abstract: The invention relates to an absorbent thin-film system made up of alternate metal and dielectric layers. With this system, color-neutral absorption results in the visual spectral region are obtained, as are a defined phase shift and a defined transmission. This film system is used for contrasting methods or contrasting systems in microscopy.

Abstract: An inspection microscope for several wavelength ranges with at least one illuminating beam path and at least one imaging beam path is disclosed. Those optical elements in the illuminating beam path and in the imaging beam path, through which beams of all wavelengths pass, are provided with a reflection reducing layer, by means of which the wavelength ranges with reduced reflection are the visible VIS-wavelength range up to 650 nm, the i-lines at lambda =365 nm and the ultraviolet DUV- wavelength range from 240 nm to 270 nm. The reflection reducing layer is a sandwich structure, comprising various material combinations, such as for example, M2/MgF2 or M2/MgF2/SiO2 or M2/MgF2/Al2O3, where M2 is a mixed substance from the company Merck, comprising La2O3.3,3 Al2O3. The optical components with reduced reflectance preferably comprise quartz glass or CaF2.

Abstract: A lighting device for a DUV microscope (1) has a lighting beam path (6) going out from a DUV light source (5) in which a collector (7) and a reflection filter system (9) are located. The latter generates a DUV wavelength band and consists of four reflection filters (8) at which the lighting beam path is reflected at the same angle of reflection alpha. In front of and behind the reflection filter system, the lighting beam path runs coaxially. The angle of reflection alpha is no greater than 30 degrees. The DUV wavelength band, lambda plus delta lambda, has a half value width of 20 nano-meters maximum and a peak with a crest value of over 90% of the radiated light intensity.
