This paper describes the modeling, deposition, lithographic patterning, and testing of filters directly deposited onto the distal tip of a fiber bundle. These spectrally sharp bandpass and long pass filters allow for the detection of Raman scattering down to about 200 cm-1 . Blocking of laser radiation above OD6 is enabled by coating both the distal and proximal tips.

This article reviews optical fibers and fiber tips, coating fiber tips, testing the coated tips, as well as the performance and applications of the coated tips

This tech note describes what wavefront is, how to specify it and how it is measured it with interferometry and direct wavefront sensing methods. 

Shrinking the size of your optical system poses some unique challenges. The most important ones are outlined here.

UVC light in the wavelengths of 207-222 has been found to efficiently kill bacteria and viruses without causing damage to human cells. Omega Optical can help you in every step of designing, prototyping and high-volume production.
