BrightLine
excitation and emission filters utilize Semrock's unique and patented single-substrate
construction, which avoids scattering, absorption, and reflection
losses that occur with the traditional multi-substrate laminated filters
based on soft coatings, which have adhesives in the optical path. When combined with Semrock's
state-of-the-art ion-beam sputtering deposition technology, the result
is the highest possible transmission of any fluorescence filters on
the market. BrightLine filter spectra also exhibit the steepest possible
edges, precise wavelength accuracy, and extreme blocking for optimal
signal-to-noise ratio performance. |

A unique design and manufacturing approach gives BrightLine dichroic
beamsplitters the steepest edges (even for unpolarized light) and
the flattest, highest reflection and transmission bands. More complete
reflection and transmission mean less stray light that causes undesirable
background and reduces signal-to-noise ratio. In contrast, conventional
soft-coated beamsplitters compromise the performance of fluorescence microscopes
and instruments by throwing away light unnecessarily and allowing
undesired background light, resulting in poorer signal-to-noise ratio. |
