WebThe FS Optical Fiber Stretcher is a highly customizable optic fiber stretcher based on a piezoelectric tube actuator. The selected fiber is wound onto the tube with a controlled tension. During operation, a voltage applied to the piezoelectric tube results in a change in diameter and a proportional change in the optical path length. WebStretchers and compressors are characterized by their dispersion. With negative dispersion, light with higher frequencies (shorter wavelengths) takes less time to travel through the device than light with lower frequencies (longer wavelengths). With positive dispersion, it is the other way around.

WebThe technique, known as Optical Tweezers, is nowadays employed in a multitude of applications demonstrating its relevance. Since the pioneering work of Arthur Ashkin, where he used a single strongly focused laser beam, ever more complex experimental set-ups are required in order to perform novel and challenging experiments. WebThe Optical Stretcher is a dual-beam optical trap that is used for trapping and deforming micrometer-sized soft matter particles, such as biological cells in suspension. The forces used for trapping and deforming objects arise from photon momentum transfer on the surface of the objects, making the Optical Stretcher - unlike atomic force microscopy or … shario white floating shelves

WebThe Optical Stretcher is a dual-beam optical trap that is used for trapping and deforming micrometer-sized soft matter particles, such as biological cells in suspension. Webdeformation; in contrast, optical stretcher [2] in a fiber-optical dual-beam trap leads to a relatively more uniform force distribution over the whole cell, and hence a more uniform deformation. Optical tweezers with near-infrared laser (e.g. =1064 nm) have been demonstrated for
