…wavelength of 266 nm, which allows
detection of smaller defects that longer wavelengths miss. This results in higher wafer yield
and better mask utilization--while saving time
in the process.
With its shorter wavelength, the Azure
can also improve disc mastering. It allows…

…output of an excimer laser
through a phase mask (essentially a diffraction grating; see Fig. 1). The phase
mask diffracts the incident laser light into
various orders, which overlap and optically interfere with each other in the mask
vicinity. This interference creates…

phase mask
can be used to produce a single target spot, which in this case causes a calcium fluorescence change
(dF/F) in four directly targeted neurons. The lower panel (b) is a statistical plot showing normalized (z-score)
fluorescence deviations using a time-varied phase mask. Here…

phase masks (uniform or chirped), automated mechanics
and control software for flexible FBG mass manufacture is
shown in figure 4.
The optical fiber is led through a fiber fixture allowing
FBGs to be written at precise positions.
