Beam aperture disks
WebContact Us Motorized iris diaphragms have 1.5 Inch Series flanges to couple directly to Oriel ® Light Sources, and a 1/4-20 mounting hole. They are driven by a fine resolution stepping motor located in the iris assembly, which can be commanded via a PC or the included controller. RS-232 and IEEE-488 communications capability are included. WebThe Airy Disk When light passes through any size aperture (every lens has a finite aperture), diffraction occurs. The resulting diffraction pattern, a bright region in the …

WebA laser beam integrator, or homogenizer, is composed of multiple Ienslets that divide the beam into an array of smaller beams, or beamlets, followed by a lens or other focusing element that superimposes the beamlets at the target plane. They can be used with both coherent laser light and other incoherent light sources. WebBeam with Gaussian intensity profile across aperture. These two extremes of aperture illumination produce slightly different answers for beam divergence, beam profile and half-power beamwidth, but make a big difference to the level of …
