In-situ at-wavelength characterization is the natural way to overcome this limitation [1]. In-situ wavefront sensing performed at the optics' operating wavelength (at-wavelength metrology) can be used not only to optimize the performance of X-ray optics, but also to correct and minimize the ...
An overview of at-wavelength metrology techniques implemented at Diamond Light Source is presented, including grating interferometry and X-ray near-field speckle based techniques. Representative examples of the application of these techniques are also given, including in-situ and atwavelength calibration ...
Extreme ultraviolet (EUV) interferometry has been successfully performed for the first time at 0.3 numerical aperture (NA). Extensive EUV "at-wavelength" testing including alignment, was performed on a newly created Micro Exposure Tool (MET) optic designed for sub-50-nm EUV lithographic imaging exp...
Fused silica is the optical material of choice for deep ultraviolet (DUV) lithographic systems. However, this material is subject to irradiation-induced compaction with ArF excimer radiation. Here we report direct, at-wavelength, wavefront measurements of DUV-laser-damaged fused silica samples performe...
We present photometry, photometric redshifts and extra galactic number counts for ultra deep 15 micron mapping of the gravitational lensing cluster Abell 2218 (A2218), which is the deepest image taken by any facility at this wavelength. This data resolves the cosmic infrared background (CIRB) be...
Raster scanning of the Milky Way in the galactic longitude range 23° – 75° was performed at a wavelength 2.4 µm by a balloon-borne telescope cooled by liquid nitrogen. With the field of view 3° x 3° the galactic plane was found as narrow as 6° (FWHM). The flux at the gala...

We designed and fabricated the transmission quarter-wave plate phase retarder at 1064 nm using optical nanometric thin films of silicon oxide and titanium oxide. Final design consists of 32 layers. Transmissions of polarizations are equal and ≥99 % and their phase difference is 90°. System cons...
