WebJun 1, 2024 · Structured light refers to the tailoring or shaping of light in all its degrees of freedom. It was the advent of the laser, however, that ushered in true control for structuring light. Better known as laser beam shaping (see “ Laser beam shaping ,” OPN, April 2003), the field took off in the late 1980s and early 1990s, driven by the ...

WebThe f/# (pronounced “F-number”) setting on a lens controls overall light throughput, depth of field (DOF), and the ability to produce contrast at a given resolution. Fundamentally, f/# is the ratio of the focal length, (f) ( f) , of the lens to the effective aperture diameter (∅EA) ( ∅ EA): (1)f/# = f ∅EA f / # = f ∅ EA WebMar 31, 2024 · OpticStudio supports 5 different models for defining fields: For the purposes of the singlet design, we will define the fields in terms of angle. Rather than having a single field representing the HFOV, three fields will be defined within the requirement of 5 degrees: (0, 0), (0, 3.5), and (0, 5).
WebThe main features of most optical systems can be calculated with a few parameters, provided that some approximation is accepted.
