美國Semrock  
Semrock公司隸屬于美國的IDEX集團。在高品質光學濾光片和鍍膜領域被公認為世界的領導者。它可提供各種標準和客戶定制的光學器件，包括窄帶濾光片、高通、低通濾光片，中性衰減片，二向色性濾光片等，具有極窄的帶寬和極佳的截止深度，透反效率>90%，在高濕環境下使用光學性能同樣得到保證。

Semrock, a Unit of IDEX Corporation, manufactures, in volume, quality optical filters of proven reliability that have set the standard for biotech and analytical instrumentation applications. ALL of Semrock's optical filters are made with hard Ion Beam Sputtered coatings – these will not degrade, be sensitive to humidity, or "burn out" with normal use, and are backed by an industry-leading five year warranty.

Semrock supports its market with three product platforms – optical filters for fluorescence instrumentation & microscopy, Raman instrumentation filters, and laser analytical instrumentation filters. Semrock's innovative catalog offerings include: the award-winning and patented BrightLine? series of fluorescence filters, which significantly improve the performance of instrumentation and microscopes for both OEM and end users; highly discriminating RazorEdge? filters for Raman spectroscopy; and the unique ultra-broadband MaxMirror? laser mirror. The versatile StopLine? series of deep notch filters has wide applicability within all three of Semrock's product platforms, as do the complementary MaxLine? highly transmitting laser-line filters. Our unique MaxDiode? laser diode clean-up filters are specially designed for popular diode lasers and offer high transmission, low ripple, and exceptional noise blocking for the cleanest diode laser output. To combine or separate laser beams use our LaserMux? filters, or to isolate popular mercury lamp lines select our efficient MaxLamp? filters. For unparalleled value try our BrightLine Basic? fluorescence filters and our EdgeBasic? edge filters.

Semrock first introduced a disruptive technology to Biotech & Analytical Instrumentation by improving and adapting the Ion Beam Sputtering (IBS) thin-film coating process, widely regarded as the premier deposition technology for making the brightest, spectrally most sophisticated and most reliable optical filters and mirrors available.

By adding many important innovations to make the IBS process suitable for use in Biotech & Analytical Instrumentation, Semrock was able to broadly introduce filters to the biotech field that have set the standard of optical performance and reliability at a level never before experienced by this community. Indeed, Semrock's advances are such that Semrock has been awarded numerous patents on its products, with more in process, and Semrock products have been recognized with prestigious industry awards. Overall, Semrock filters are brighter, far more durable, and spectrally more sophisticated than those made by other coating technologies, thus driving significant improvements for our customers and their applications, such as faster measurement times, reduced downtime, repeatable manufacturing, and lower optical component count.
 

Another key Semrock advance has been to make its unique products repeatably manufacturable in high volumes, permitting OEM customers to have a dependable supply, and catalog customers to order direct from stock. At Semrock we also adhere to high levels of internal process control and reliability testing that well exceed the norm in the industry. We have passed many quality audits by major OEM customers.

But it is not enough to have a superior technology – the filters must be optimally designed to meet our customers' true needs. At Semrock, since we focus all of our efforts on biotech and analytical instrumentation applications, we thoroughly understand our customers' requirements. We speak your language! This is why Semrock's products have been incorporated into so many important instruments made by leading biotech and analytical instrumentation makers around the world. Indeed, we have shipped hundreds of thousands of ion-beam sputtered filters to date.

Founded in September 2000, Semrock is based in Rochester, New York, a well-known center of optics, and has sales offices throughout the United States, and an international network of distributors. In October 2008, Semrock became a unit of the Health and Science Group of IDEX Corporation.
