Semrock, located in Rochester NY, USA, 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.

​

Semrock has improved and adapted the Ion Beam Sputtering (IBS) thin-film coating process to make the IBS process suitable for use in Biotech & Analytical Instrumentation. With this Semrock has been 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 repeatedly manufacturable in high volumes, permitting OEM customers to have a dependable supply, and catalog customers to order direct from stock.
