Chroma Technology

Description :

Chroma's 49009 ET - Cy5 Narrow Excitation single band filter set is composed with an excitation filter model ET640/30x center wavelength at 640nm with 30nm bandwidth, T660lpxr beamsplitter, and ET690/50m emission filter center at 690nm with 50nm bandwidth.

Chroma's 49009 serie of single band sets features our highest throughput sputter coatings (ET) which achieve the highest transmission levels for interference filters. These filters have very steep transitions from peak transmission to high optical density to best exploit the spectral properties of modern fluorochromes with short Stokes shifts. This is because steep transitions allow for very little spectral separation between excitation and emission bands. These filters offer the greatest hardness and durability against environmental factors such as high heat and humidity, and are covered by Chroma's lifetime warranty.
