System for maintaining the sharpness of the image for the light microscope
Dokulil, Jakub ; Bouchal, Petr (referee) ; Dostál, Zbyněk (advisor)
Live imaging je klíčovým nástrojem pro moderní biologické objevy. Bez techniky pro udržení ostrosti obrazu je však stěží proveditelný. V této práci předkládám aplikaci optických vírů pro axiální lokalizaci vzorku tak, aby se obraz mikroskopu udržoval zaostřený. Experimentalní sestava pro axiální lokalizaci z předchozích experimentů byla přepracována, aby se rapidně zmenšily její zástavbové rozměry, tak, aby jí bylo možné integrovat jako modul do mikroskopu. Sestava byla následně realizována a byla úspěšně experimentálně otestována. K tomu bylo třeba také navrhnout řídící software. A připravit skript se zpětnou vazbou pro budoucí integraci do mikroskopu.
Design of projection illuminator
Přikrylová, Ivana ; Vacula, Daniel (referee) ; Antoš, Martin (advisor)
The aim of this diploma thesis is to design a suitable reflector concentrating a light beam into a circular hole in a gobo. The light beam behind the screen should have good efficiency and at the same time good homogeneity. For the reflector design and analysis a software for designing optical systems called LightTools was used. The reflector was designed by six different methods. Several smooth and several faceted reflectors were designed. The selected reflector was analyzed in combination with a varifocal lens. For selected reflector was designed mechanical store with respect to the anticipated operating conditions. This thesis serves as the basis for the producing of the reflector.
Design of an active protection system LIDAR for the detection of subsonic missiles
Gedeon, Sebastián ; Vilém, Jan (referee) ; Antoš, Martin (advisor)
The diploma thesis focuses on the design of an Active protection system LiDAR, with emphasis on the research for the operation of these systems and the components of which the system consists. It specifies the basic optomechanical parameters that the designed system must achieve. The thesis introduces a conceptual design of an optical system for ground surveillance and aviation surveillance. LiDAR systems are made of off-axis or Cassegrain telescopes. As a part of this thesis are also designs of an optical illuminating system and a zoom lens for infrared imaging.
Mechanical and optical design of spectroscopic system for reactive ion etching system
Šilhan, Lukáš ; Dostál, Zbyněk (referee) ; Šerý, Mojmír (advisor)
Measurement of absorption spectra of plasma during reactive ion etching enables characterization of etched species and control over the etching process. Aim of this diploma thesis is to design spectroscope with Czerny-Turner configuration for reactive ion etching system. Developed spectroscope achieves 1 nm resolution in 350-800 nm range. Device was tested during reactive ion etching of silicon.
Optical design of telecentric F-theta objective
Perháč, Timotej ; Zámečník, Jan (referee) ; Antoš, Martin (advisor)
This thesis deals with optical design of f-theta lens for purposes of precision micromachining using a laser beam. Optical design consists of creating a nominal design according to specifications given by Meopta – optika s.r.o company and a tolerance analysis, which describes manufacturability of given design. Specifications given are most importantly diffraction limited image quality, correction of distortion throughout the field and telecentricity of systém in image space. F-theta lens in this thesis was created using an optical design software called Zemax.
Design of the telescope spectrograph for distant object analysis
Drobil, Tomáš ; Pořízka, Pavel (referee) ; Novotný, Jan (advisor)
Meteor spectra obtained from orbit include many spectral lines in the ultraviolet region, which is mostly absorbed by the atmosphere and thus cannot be observed from ground stations. This bachelor thesis focuses on the design of a spectrograph, placed in a 2U CubeSat, suitable for meteor observation and its spectral analysis in the range from the ultraviolet to near-infrared region. The design includes choice of a suitable camera. Based on the required parameters, several designs have been created, and the process is summarized in the last chapter. The research study of telescopes combined with spectrometers used for meteor observations is also included.

Raman assembly for radiation analysis
Stránská, Lenka ; Ježek, Jan (referee) ; Dostál, Zbyněk (advisor)
For Raman spectroscopy is a need to introduce a laser light into an optic fiber and analyze a collected light at the same time. Therefore it was proposed a specialized optical system. This system can also be used to measure other spectroscopy methods such as photoluminescence. In the theoretical part of this theses, was discussed both mentioned methods and their instrumentations. In addition to the Raman spectroscopy, was also shown some special cases of Raman spectroscopy for enhanced measurement of Raman scattering. The problem of weak signal detection and its reading is also discussed in the theoretical part of the thesis. In the practical part of this thesis was discussed the mechanical design of the optical system and the choice of optical elements that are used in the system. Next, is introduced the manufactured system, which design is based on the parameters of the chosen optical elements. The practical part of the thesis ends with an assembly and testing of the proposed system.
SMV-2020-42: Research and development of aspheric lens
Šarbort, Martin ; Holá, Miroslava ; Lazar, Josef ; Vašátko, Albert
The aim of the contract research project was to design an optical system that generates a laser beam of a specific shape. The optical system was based on a specially designed aspheric lens. The lens parameters were calculated using an optimization algorithm. The properties of the generated beam were verified in specialized software for the design of optical systems.
