Aspheric lens is being used to collimate a laser diode beam. Copyright ©2019 Go!Foton All Rights Reserved. The resulting parabolic index distribution has a steepness that is determined by the value of the gradient constant, √A. PDF. With over 35 standard lenses in LightPath’s catalog to choose from, however, this can sometimes be a confusing task. Model. A light ray that has traversed one pitch has traversed one cycle of the sinusoidal wave that characterizes that lens. Recommended Storage and Handling of Lenses.

In the world of optics, web searches are no substitute for our direct, comprehensive, customer-tailored application assistance. Simplified Mounting. Laser diode beams typically have a slow axis and a fast axis (see Figure 2). The objectives are corrected for standard laser diode cover glass and optimized specifically for collecting and collimating light output from laser diodes. Our experienced design team will offer custom laser diode collimators with desired divergence and beam size and shape. A wide variety of laser diode collimating lens options are available to you, such as optical. packages containing multiple broad emitters in an array. But opting out of some of these cookies may have an effect on your browsing experience. Laser diode collimators are used to collimate the highly divergent beam that is emitted by a laser diode.

In either case, most laser diodes require a collimating lens with a large numerical aperture (NA) to efficiently capture the widely The Pick-Up Lens is mounted in an anodized aluminum holder. It consists of a laser diode holder, a collimating lens holder, and a high numerical aperture (NA) collimating lens, with a focal length f. The len s is housed in a threaded receptacle that is screwed into the collimating lens holder. The fast-axis collimating lens shown in blue reduces the divergence of the laser diode beam to a value close to zero. Collimated laser diodes are an assembly of a laser diode with a specified collimating lens within a small package. Call us now for a Universe of optimal design solutions at. There are different collimators that are available: Some broad-area emitters are sold with a fast axis collimation lens (FAC lens) fixed to the output facet. For most laser diodes, the beam divergence is so substantial that it is advantageous to use aspheric lenses for beam collimation in order to avoid significant spherical aberrations of the collimated beam. If the desired beam radius is relatively small, a micro lens may be employed. At Universe Optics, our comprehensive value-added and custom design lens capabilities will accommodate any non-standard design or manufacturing criteria. However, many applications exist where a single lens is used to either focus or collimate the beam. 2 www.LightTrans.com. ELECTRON provide customized solutions diode laser modules to fit your requirements. The distance between the laser diode output facet and the collimation lens needs to be identical to the focal length of the lens, because otherwise the beam after the … This website uses cookies to improve your experience while you navigate through the website.
