49000 Series - ET Sputtered Single Band Filter Sets
This series features Chroma’s Modified Magnetron sputter coatings (ET) which achieve the highest transmission levels for interference filters. Like the 41000 series, these filters also have a very steep transition from peak transmission to high optical density to best exploit the spectral properties of modern fluorochromes with short Stokes shifts. These filters offer the greatest hardness and durability against environmental factors such as high heat and humidity, and will last much longer than soft-coatings. Additionally, use of our ET filters assures image registration between filter sets in imaging systems which are otherwise in perfect register.
**Prices are for unmounted filter sets. For the appropriate filter cubes/holders, please see our 91000 Series or contact us.**
The narrow-band excitation provided by this filter set is useful in applications where fluorochromes such as Texas Red or AlexaFluor 594 are also present in the same sample. This set will minimize bleedthrough of these fluorochromes.
