Unique Manufacturing Capabilities

Gray Scale Technology

In order to achieve the best optical performance available, Gray scale technology allows for the creation of a wide variety of shapes. Traditional binary optics rely on a "stairstep" shaped approximation of the ideal surface shape. Gray scale, however, can actually create that ideal shape. Curves, ramps, torroids, or any other shape is possible. Depending on the design, Jenoptik Microoptics can create feature sizes as small as 3 µm in gray scale and about 0.5 µm in binary products.

 

Nano-Optics

The wide range of micro and nano optical applications requires optical elements with typical structure sizes beginning at several nanometers and ending in the range of millimeters. In the case of diffractive optics, it is known from the grating equation that the feature size is proportional to Lambda/NA, which implies for applications in the UV-wavelength range to typical structure lateral dimensions in a range between 1 µm down to 100 nm and below. The fabrication of products with minimum features sizes down to the sub-micron range requires high-resolution lithography techniques. Jenoptik Microoptics Nano Lithography is a maskless process in which we are able to pattern features with critical dimensions down to 100 nm (+/- 20 nm). Positional accuracy is +/- 40 nm. This is provided on substrates up to 7" x 7" square in fused silica, quartz glass and optical glasses. These substrates can be etched with aspect ratios as high as 1:15. Products include diffractive lenses, fine-pitched gratings, polarizing optics, as well as multi-function optics.

 

Full Spectral Range Capabilities

The flexibility of our technologies processes make it possible for Jenoptik Microoptics to manufacture unique microoptics in a variety of materials. We can provide our customers with the right solution to match the high accuracy requirements of the UV region and the new developments of the IR region.

Jenoptik Microoptics also has the capability to make high-performance gray scale injection molds for plastic microoptics.

 

NIR Region, Telecom & Biomedical Applications

The near infrared region of the electromagnetic spectrum, covering a range of wavelength from 700 nanometers to 3 microns, lies just beyond the sensitivity of the eye. Applications like fiber optics in telecommunication use wavelengths in this region to achieve both high transmission and a relative low dispersion making it possible to communicate over longer distances. This region is becoming important for some surgical procedures and material processing in the biomedical and industrial markets.

Mid and Long Wave Region, Defense & Security

The mid and long wave infrared regions, covering a range of wavelengths from 3 to 14 microns, have become very important for military applications. At this region it is possible to obtain sharp images on both close and distant objects used for military surveillance and sighting. Thermal imaging capabilities are also being used for medical diagnosis and industrial monitoring.
