Optical Surfaces Ltd has developed a new approach, using a series of pre-aligned beam collimator sub-assemblies, for Modulation Transfer Function (MTF) testing of large diameter military optical ...

The technique requires a conventional microscope along with a 1-watt laser and a fiberoptic collimator. A digital camera collects the optical data for processing. While a laser used to be exotic ...

optical switches, circulators, WDMs, in-line polarizers, collimators, patch cables, fiber optic homogenizers, and more. We specialize in the fields of light (photon) transmission, switching, ...

Sensitivity of relative Raman counts versus probe distance for different lens tube optic focal lengths ... shows the excitation spot size sensitivity as a function of excitation collimator numerical ...
