X-ray optics

cosine is world leading in the development of novel X-ray optics technology. The Silicon Pore Optics technology SPO, developed by cosine for the European Space Agency, offers significant advantages for a variety of applications.

cosine is also expert in glass micropore optics technology and can develop and deliver systems based on these ultra-low mass X-ray optics. With its expertise in X-ray optics cosine can solve your X-ray imaging and focussing challenges.

Particle contamination

cosine has developed a contactless method, based on the detection and analysis of scattered light, to efficiently measure particles of a few micrometers on highly reflective structured surfaces. This high-yield technology, combining specialised light sources, line CCDs and dedicated image analsysis is successfully used on silicon substrates in high throughput stacking robots.

Silicon wafer bonding

Silicon wafers are commonly used in the electronics industry to make electronic chips, but can also be bonded together to form X-ray lenses. An X-ray lens needs a large surface, but a stack of precisely structured wafers can cause the same effect and as such makes the large surface redundant.
Bonding and stacking tens of silicon wafers is a technology initially developed by cosine for a novel type of light weight X-ray lenses. Our specialised fully automated stacking robots can elastically deform and directly bond tens of patterned silicon wafers with micro-meter accuracy on top of each other.
The silicon plates can be coated, grooved, wedged and structured with different patterns. The stacking robots have been developed in house and combine standard wafer industry technology with novel metrology solutions to achieve high accuracy and high yield stacking.
