For a long time, the diffraction limit defined by Ernst Abbe defined the natural barrier that restricts the resolution of small objects. To overcome this limitation multiple techniques like STED, STORM, PALM, TEM or others were developed, using advanced illumination and detection technologies.
In its original sense, the Abbe limit states, that the shorter the wavelength of the particle, the higher the resolution. Therefore the observability to resolve small structural features in the image is also higher.
This fundamental law applies to visible light and to all photons of the electromagnetic spectrum. That includes the high energy containing photons of extreme UV (XUV), roentgen radiation (Xray), and electrons.
While the diffraction limit is still valid, using XUV (CWL: 13.5nm), soft-Xray, and high energy containing electrons, it is possible to push the resolution higher. Thus, enabling to resolve the fine structural features and dynamics in biological processes (cells, human body) as well as materials.
To fulfill these needs and leverage the high potential of XUV/soft-Xray, XIMEA added a new MJ042MR-GP-P11-BSI-UV model to the scientific portfolio of cameras. The model is equipped with the new Gpixel GSENSE400BSI-UV (PulSar) sCMOS sensor that is combined with Peltier cooling and USB3 interface.
The camera body is extended by a standard DN 63 CF vacuum flange. Additional flange formats are available upon demand. By using the new Pulsar sensor the spectral range is extended from IR, VIS, and UV into the soft-Xray regime, covering a maximum range from 0,5 to 1000 nm.
