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.

Fiber guided illumination module
Kropáč, Vlastimil ; Kvasnica, Lukáš (referee) ; Dostál, Zbyněk (advisor)
This diploma thesis describes the design of the illumination system for a Coherence--Controlled Holographic Microscope (CCHM). The theoretical part mentions the history of microscopy, the principle of holography and individual types of interference microscopy. To get closer to the topic, individual light sources and an overview of current illumination systems are mentioned. The diploma thesis also describes the procedure of designing a fiber-optic illumination module for microscopy from optical design through design of construction to the last step, which is assembly and testing of the module.

Design of indoor lighting in a trend of Human Centric Lighting
Ruml, Filip ; Baxant, Petr (referee) ; Antoš, Martin (advisor)
The main tasks of the thesis lie in summary of present state in Human Centric Lighting field, in the optical design of luminaire and in practical verification of the proposal. The design is developed in software LightTools and for the verification of functionality the software Dialux EVO is employed. The luminaire is designed primarily with respect to the influence of light on the man and the physiological, psychological and behavioural responses in humans. The thesis is created in cooperation with the company Robe Lighting s.r.o. The proposal of the luminaire corresponds to the current state of knowledge in the area of light influence on humans. The designed luminaire in the trend HCL is distinguished by the high quality of emitted light but also with higher costs of the operation.

The conceptual designs of conversion lens for the OptoNS equipment
Pintr, Pavel
The company Elmarco uses a classical commercial objective with a focal length of 200 mm for a detection of shape of Taylor´s cone. This system displays a scene with the horizontal size of 23 mm and doesn´t show a scene with a required detail. The commercial solutions don´t exist for the long working distances of 550 mm. We prepared optical solutions of conversion\nlens and the one solution of a main objective. These optical solutions should fulfill required optical parameters.

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 and optimization of varifocal lens
Vilém, Jan ; Vacula, Daniel (referee) ; Antoš, Martin (advisor)
The thesis deals with the design and optimization of varifocal lens for projection illuminating purposes, its mechanical design and manufacturing drawings. It was proceed in the cooperation with Robe Lighting s.r.o., which defined requirement for a new projective objective lens. Lighting fixtures development is a very specific industry with a number of unusual conditions for design and methods of using of the optical systems. In this paper conditions for imaging quality will be defined and a new design of the lens with corrected distortion will be created based on the definition of the conditions.
