The Confocal Laser Scanning Microscope (CLSM) is an optical microscope that includes a laser light as a light source and an electronic system which helps on image processing. It obtains high-resolution and extremely thin optical image sections, removing the interference caused by the light arriving from the different optical fields across the thickness of the sample, and focusing on a single pl...

The uniqueness of polarization microscopy lies in the use of light beams with controlled states of polarization. With such beams, optical properties such as birefringence, dichroism, and optical activity are detectable, and optical constants are determinable in an exceedingly small sample volume. Since birefringence and dichroism generally reflect the arrangement or properties of material the d...

Conventional material removal of BK7 optical glass will normally result in brittle fracture at the surface, generating severe subsurface damage and poor surface finish. Subsurface damages induced by grinding strongly influence the mechanical strength and optical quality of optical glasses. However, through ductile mode grinding it is possible to reduce the surface and subsurface cracks. It is m...

in this research, the effect of 2.3 wt.% aluminum addition on the microstructure and tensile properties of high manganese austenitic steel fe-18mn-0.6c was studied. for this purpose, the samples were investment cast, homogenized and hot rolled. tensile testing was carried out at ambient temperature. microstructural investigations and fractography on the steel samples were carried out using an o...

A microscope for quantitative analysis of the birefringence properties of samples is introduced. The microscope is used to measure variations in the slow optical axis position (SOAP) across hen egg-white lysozyme, glucose isomerase and fibronectin crystals. By comparing these variations with indicators of diffraction quality, it is shown that the optical properties of a protein crystal provide ...

An elegant method is proposed and demonstrated for tracking the location and movement of nanoparticles in an optical microscope using the optical phenomenon of caustics. A simple and reversible adjustment to the microscope generates caustics several orders of magnitude larger than the particles. The method offers a simple and relatively inexpensive method for visualizing such phenomena as the f...

ZnO and ZnO:Mn nanocrystals synthesized via reverse micelle method. The size, band gap, Urbach energy, optical constants and penetration depth of nanocrystals were calculated by UV-vis spectroscopy data. The surface morphology was studied with the use of scanning electron microscope (SEM). Moreover the samples exposed to Gama ray source of 60Co and their thermoluminescence properties...
