Mega-9
Advanced optical narrow bandpass
filters and beam splitter cubes
About us
Shanghai Mega-9 Optoelectronic Co., Ltd., founded in 2006, is a leading technology manufacturer in optical bandpass filters and beam splitter cubes in China. Mega-9 has excellent fabricating facilities, including advanced coaters, ultrasonic cleaning line, high accuracy spectrophotometers,and super cleanrooms. We have over 20 years coating research and developing experience, therefore the technical supporting or total solution providing is one of our strong points. Mega-9 is an ISO9001:2008 approved company, especially Mega-9 is honored as "State high and new enterprize" approved by state scientific and technological commission.
Mega-9 focuses on fabricating high end optical filters, including narrow bandpass filters, polarising beam splitter cubes, non-polarising beam splitter cubes, solar simulation filters, high temperature filters and other edge filters. Mega-9's bandpass filters are thin film Fabry-Perot interferometer structure formed by ion assist E-beam evapoeration deposition techniques, generally with 3 to 6 cavities based on bandwidth and blocking level requirement. For most of machine vision application, the blocking level of the filters is OD3 average(T<0.1%) over 400 to 1100nm, however for most of fluorescence or enzyme label application, the blocking level is OD5 or OD6 over 200 to 1200nm. The position wavelength of the bandpass filters does not shift due to the proper ion assist process.Most of mega-9's filters do not use absorptive glass to assist the blocking, all the rejection bands are completed by coatings. Although this technology increases the fabricating cost, the imaging quality improves much compared with aborptive glass in which there are many defects such as bubbles, striation and stress.The application fields of Mega-9's filters concern machine vision,security monitoring, face recognition, liscence plate recognition, photorejuvenation, large screen multi-touch panel, biochemical analysis, distance measurement,PCR fluorescence, enzyme label, astronaumy observation, laser interferometer,and other optical instruments. For beam splitter cubes, they are formed by two right angle prisms cementing together with NOA 61 adhesive glue. All the input and output surfaces are coated with AR coatings. The available wavelength range for beamsplitter cube is from 400nm to 1600nm. Most Mega-9's optical filters and beam splitter cubes are exported to USA, Germany, UK, Israel, South Africa, Japan and France.
Mega-9 has thousands of stocked filters or prism cubes for customers to select. Free sample is available upon request. Fast delivery, high quality and economical solution is your best choice.
