Shanghai Mega-9 Optoelectronic Co., Ltd., founded in 2006, is a leading technology manufacturer in optical band pass filters and beam splitter cubes in China. Mega-9 has excellent fabricating facilities, including advanced coaters, ultrasonic cleaning line, high accuracy spectrophotometers, and super clean rooms. We have over 29 years coating research and developing experience, and the technical supporting or total solution providing is one of our strong points. Mega-9 is an ISO9001:2015 approved company, especially Mega-9 is honored as "State high and new enterprise" approved by state scientific and technological commission since 2012.
Mega-9 focuses on fabricating high end optical filters, including narrow band pass filters, polarizing beam splitter cubes, non-polarizing beam splitter cubes, solar simulation filters, high temperature filters and other edge filters. Mega-9's band pass filters are thin film Fabry-Perot interferometer structure formed by ion beam assist E-beam evaporation deposition technique. The blocking depth can be achieved up to OD 6 according to the application needs. The wavelength position of the band pass filters does not shift due to the proper ion assist process. For imaging system, to improve the imaging quality, most of mega-9's filters do not use absorptive glass to assist the blocking, but use all-dielectric multilayer coatings. A low auto-fluorescence substrate is adopted for fluorescence application fields. The narrowest bandwidth can be achieved is 2nm at present.
The typical feature for Mega-9's polarizing beam splitter cubes is the high contrast ratio between the P and S polarization, generally it is bigger than 1000:1 over specified broad wavelength range. And the feature for non-polarizing beam splitter cubes is the small separation of P and S polarization over the entire wavelength range. It is regularly smaller than 5% for the difference P and S polarization transmission or reflection.
The application fields of Mega-9's filters include PCR fluorescence, enzyme label, biochemical analysis, gel-imaging, intelligent car, drone, astronomy observation, laser interferometer, and other optical instruments.
Most Mega-9's products are exported to USA, Germany, UK, Israel, South Africa, Japan and France.
Mega-9 has ten thousands of stocked filters or prism cubes for customers to select. Free sample is available upon request. Fast delivery, high quality and expertise technical service is your best choice.
