Does Simplified: An Easy Guide To Applications, Types And More!
DOEs stands for Diffractive Optical Elements. These are optical components that are made of subwavelength structures with diverse, complicated arrangements. Diffractive Optical Elements are used for manipulating the phase of light to create an intended output for specific functionalities. In many ways, the concept and principles for DOEs are same as “diffractive grating”. NIL Technology offers you diffractive optics for diverse needs, and before you go ahead and place an order for your company or project, here are some aspects worth knowing about DOEs.
The popularity of diffractive optics has increased considerably in recent years, considering the benefits that these offer over heavy refractive counterpart. Using nanolithography and new techniques of fabrication, it is now possible to engineer and design diffractive optics in a diverse range of sizes. From diffractive optics that measure a few millimeters to the smaller ones that measure in nanometers. Older optical components have been now replaced with DOEs, primarily because the cost effectiveness and overall efficiency cannot be compared. Also, DOEs are extremely compact, something that’s really desirable in optics.
DOE applications at a glance
DOEs are used for diverse kinds of optical projects. The most common example being Laser Detection And Ranging, also called LADAR, while it is also used for Light Detection And Ranging. DOEs are also used for position sensors and motion detectors. There are companies that can customize and design DOEs for specific needs, and you can expect to improve performance considerably for each project depending on what you seek. Expect to get high definition results, better aspect ratios, steep side walls and reduced roughness on DOEs that have been designed by some of the biggest companies.
Types of diffractive optics
Diffractive optics can be classified into three broad categories based on applications. These are namely called diffusers, beam splitters and beam shapers. If you need diffractive optics, make sure that you select a company that relies on better production techniques and has experience and expertise in high-precision diffraction structures. They should also be able to combine and make the most of both diffractive and refractive optics as per the needs of the project and must be capable of handling diverse specifications. Since intensity profiles can be really complex, ensure that the company is well-versed with all aspects of advanced DOEs.
