From the March 2010, BioPhotonics article, " Getting More System for Less"

"The cost of the filters in the system was reduced by mounting them in injection-molded plastic instead of putting them in machined metal. The filters were from Semrock Inc. of Rochester, N.Y., and offered what McCarthy characterized as very good performance at an inexpensive price."

"What a great company - I really appreciate the thoughtful response by Semrock and the extra effort that was involved here.
Thank you."

"We are a microscope sales and service company based in Montana. I work almost exclusively in MT, AK and Antarctica. The success with your filters and the consistent customer amazement of the quality of your filters has lead me to carry Semrock exclusively. Only on rare occasions do I deviate. When I see a failing filter set in any of my remote locations I recommend to the customer that it is not a place to buy cheap or inferior filter sets. Many of the places I get to there is no such thing as next day shipping so burned out filters are not a good risk.  Also we get world class scientists down for their once-in-a-lifetime opportunity to study in that environment, you want the best that money can buy."
