After understanding the various components, we can start “working with the microscope.” To get the best resolution and contrast from the microscope, the practice of “Koehler Illumination” should be understood and followed by every serious microscopist. Step-by-step instructions as well as illust...
imaging system, and light detector. In conventional microscope, illumination emitted from the light source interacts with the specimen, producing absorption, scattering, or fluorescence. The resulting light from the object is collected by the optical imaging system and focused onto the image sensor, wh...
At its core, SPED light sheet microscopy consists of a simple and scalable implementation, requiring the introduction of a transparent block of material in the detection path of a standard light sheet microscope, for generating an extended depth of field by inducing uniform spherical aberrations. By...
Light sheet microscopes reduce phototoxicity and background and improve imaging speed compared to widefield and confocal microscopes. However, when equipped with Gaussian beams, the axial resolving power of a light sheet microscope and the observable fie
We foresee that a wholly fibre based light-sheet microscope would take the form of two parallel optical fibres (or a single dual-core fibre) with carefully designed termination to maintain the orthogonal orientation of excitation and collection pathways. In addition, there is a potential to reduce...

quarter-wave (λ/4) phase plate. The annular aperture is placed between the light source and condenser lens and the phase plate after the objective inside the microscope optics. Ring-shaped light that passes through the aperture is focused by the condenser onto the biological specimen to be ...
This simulation computes the amount of light being detected by the imaging sensors of the microscope relying on the principles of conservation of energy. In contrast, visually plausibility can be achieved by creating a synthetic image that has the same visual appearance of the real one using ...
An oblique light-sheet microscope was used in this observation, in which an illumination and a detection objective were arranged 45° to the samples (Supplementary Fig.1b). The direction of movement of PD-1+ cells changed with the blood flow direction in the tumor microcirculation. Similar ...
