The 10 milliarcsec resolution element of a 12 meter telescope [high definition space telescope] (diffraction limited at 0.5 micron) would reach a new threshold in spatial resolution. It would be able ...

A perfect 2.4-meter mirror observing in the visual (i.e. at a wavelength of 500 nm) has a diffraction-limited resolution of around 0.05 arcsec, which from an orbital altitude of 250 km corresponds to ...

The diffraction spikes so familiar to us in space images are an intrinsic property of the telescope. Reflecting telescopes have two mirrors: a large primary and a smaller secondary.

Diffraction gratings are beautiful things, ... The big dial is how the operator selects the desired wavelength, and is labeled in ‘mu’ (or milli-micro), but ...

A method has been devised that extends the resolution of X-ray crystal structures beyond the diffraction limit. This might help to improve the visualization of structures of proteins that form ...

Diffraction in this regime is possible due to the short interaction time of the projectile with the atomically-thin crystal, limiting the momentum transfer to the grating,” the researchers ...

Laser diffraction needs a smaller representative sample when compared to sieving. However, it can also use larger samples. For a dry-dispersed laser diffraction experiment, the sample size ranges ...

Lab scale: Members of Ashley Bucsek’s group can now use three-dimensional X-ray diffraction to study polycrystalline materials on campus, whereas they would previously only have been able to do this ...
