Optical collimator wiki
WebIn optics, a collimator may consist of a curved mirror or lens with some type of light source and/or an image at its focus. This can be used to replicate a target focused at infinity with little or no parallax . In lighting, collimators are typically designed using the principles of nonimaging optics. [2] WebOptical Density (OD) describes the amount of energy blocked or rejected by a filter. A high optical density value indicates low transmission, and low optical density indicates high transmission. Optical densities of 6 or greater are used for extreme blocking needs such as Raman spectroscopy or fluorescence microscopy.

WebCollimators are used for X-ray, gamma-ray, and neutron imaging because it is difficult to focus these types of radiation into an image using lenses, as is routine with electromagnetic radiation at optical or near-optical wavelengths. Collimators are also used in radiation detectors in nuclear power stations to make them directionally sensitive.

WebMar 15, 2024 · It covers a wide range of fiber optic devices such as optical splitters, optical combiners, and optical couplers. A fiber optic coupler is a device that can distribute the optical signal from one fiber among two or more fibers, or combine the optical signal from two or more fibers into a single fiber.
WebFocusable Collimators consist of two separate components: a fiber optic collimator and a fiber optic refocusing assembly. The fiber optic collimator utilizes a PCX lens positioned at the focal length from the optical fiber tip. These collimators are available with FC or SMA threads, and easily couple to standard 0.22 NA fiber optic cables.
