As a pioneer in filter technology for more than 30 years, Omega Optical has developed intellectual property related to filter design and manufacturing technologies, resulting in significant advancements in filter performance.
SYSTEM FOR MULTISPECTRAL IMAGING OF FLUORESCENCE - PATENT #9,155,474
This 2015 patent describes a fiber-based confocal scanning system that indexes spectral information into the time domain. It enables the detection of up to 15 spectral bins within 2.5 microseconds using a single PMT detector. The technology leverages Omega's thin-film optics expertise with a serial array of coated fiber tips in the detection path. Omega has perfected the art of fiber-tip coating to accomplish this work.
3RD MILLENNIUM TECHNOLOGY—PATENT #6,918,673
A patented hermetic assembly which improves filter life and environmental stability. The elimination of optical epoxies in this air-spaced filter results in reduced auto-fluorescence, improved parallelism and flatness, and improved heat tolerance.
SPECTRAPLUS TECHNOLOGY—PATENT #5,646,781
Omega Optical's 1997 patent for a triple-bandpass coating is significant for its image enhancement capability. This coating transmits bands of pure color while eliminating the regions of “color confusion” during both image capture and image display. The technology has use in applications as diverse as HDTV cameras, sports optics, and medical lighting.
MULTI-BAND TECHNOLOGY—PATENT #5,173,808
Omega holds the 1992 patent on all filters with multiple passband and rejection bands, including dual-band, triple-band, and quad-band filters. These filter types have broad application in a variety of life science applications for visualizing multiple fluorophores simultaneously.
