For simplicity, it is often assumed that the imaging system consists of a single thin lens. In the case of the barcode reader, the imaging system consists of several thick lenses and aperture stop, therefore this assumption is not valid. One of the topics of the research is to study the right position to place …

During the manufacture of semiconductor devices such as Mosfetts it is essential to inspect the device for cracks and other damage. It is required to obtain 3D images at NIR wavelength for which the semiconductor is transparent. The images should have high resolution and should be acquired at high speed. This project is carried out …

LINX is a NWO-TTW perspective programme with the aim to apply various lensless imaging techniques, from ptychography to scatterometry, while using wavelengths in the EUV and Soft X-Ray regime. This programme is a collaboration with five largest Dutch universities and major (inter)national industry partners with a budget of ±4MEuro. The aim is to generate innovative …

Through an optical system an image can be formed. But how to improve its resolution? Is there a limit? Can we reduce the number of optical elements with the same results? Can we even obtain an image without any lens? Here are some questions we are eager to solve.
Focused radially polarized beam is used to image non-fluorescent specimens to enhance the spatial resolution of conventional confocal microscopes.

In the back of a cupboard of our group, (Optics Cluster at the Imaging Physics department of Applied Sciences), a box full of interesting objects had been hiding for almost thirty years. Nestled amongst prisms and scopes, was a mysterious microscope. Most of the objects dated from the mid-20th century, but this microscope looked older …
Our Post-doc Yifeng Shao has invited our former Professor, Joseph Braat, for an interview published on Advanced Photonics to look back at his career, the development of optical storage and lithography in the Netherlands, and his transition to academia coming from Philips. You find the interview here.

Jeff Meisner, postdoc in the Optics Group of the Department of Imaging Science, has passed away on January 1st. Jeff became severely ill one year ago. The medical doctors considered his condition at the time life-threatening and decided to amputate one of his feet. Around Christmas last year, the disease returned and he was taken to the …
