Product Overview
Description
Product Description
The different types of DOEs (beam-splitters, pattern generators, kinoforms, beam shapers and gratings) utilize a microstructure surface relief profile for their optical function. Light transmitted by a DOE can be reshaped to almost any desired distribution,just by diffraction and the subsequent propagation. The DOE only encodes the shape of the desired intensity pattern, but maintains other parameters of the incident light source (e.g. beam size, divergence, polarization).
Due to their design flexibility, DOEs can have optical functions that can otherwise not be achieved at all, or only with
complicated optical systems. Moreover, compared to refractive optical elements, DOEs are typically much thinner and lighter,making them an attractive replacement in a number of applications.
In most scenarios the incident laser beam is collimated, or focused to a fixed distance behind the DOE. Wavelength Nanjing can offer solutions also for non-collimated or partially collimated light sources. To do so, the DOE microstructure combine pattern generation with focal power. In addition, the focusing properties of Wavelength Nanjing’s DOEs are not limited to fixed working distances. Instead, our pattern generators can provide required focal power to achieve focusing of the laser to strongly inclined target planes. In fact, the best focus location per diffraction direction can be matched to almost arbitrary surfaces.

Operation Principle
Advantages and Disadvantages
Advantages
1. Can reduce the size and weight of a camera lens. The diffractive elements in a lens are very thin and light, and work in conjunction with refractive elements to reduce the physical size of the optical path.
2. While a Fresnel lens on its own does not eliminate chromatic aberration (CA), the phase of the aberration can be different
2. While a Fresnel lens on its own does not eliminate chromatic aberration (CA), the phase of the aberration can be different
to that of the refractive elements and so, with careful design, they can cancel each other out. Therefore, diffractive-optics
lenses usually exhibit excellent control of CA.
Disadvantages
1. Cost is higher, partly due to the more challenging manufacturing procedure. There is some evidence that
optical quality control is more difficult, too. Contrast
2. And light-transmission efficiency have also been noted as being behind more conventional refractive optics. But with the
lenses usually exhibit excellent control of CA.

2. And light-transmission efficiency have also been noted as being behind more conventional refractive optics. But with the
trend in favour of lighter and less bulky photographic gear, diffraction optics is likely to be an increasingly accepted
option for the modern photographer.
