Set description

This single-band filter set is perfectly optimized for brilliant, dense multi-color detection with quantum dot nanocrystals. The highly transmitting, deep-blue exciter achieves maximum quantum dot excitation efficiency while virtually eliminating any DAPI or Hoechst excitation. The emitter has high transmission, steep edges, and a narrow bandwidth to perfectly match the Qdot 655 emission with minimal crosstalk from neighboring Qdots. With its exceptionally wide and flat transmission and reflection bands, the dichroic not only accommodates all Qdot nanocrystals but does so with a wide range of possible UV and blue excitation wavelengths. And with the "no burn-out" performance shared by all BrightLine filters, this set is the ideal tool for applications that depend on the superb photostability and archivability of quantum dots.

Filter	Average Transmission	Center Wavelength	Bandwidth *
Exciter	> 90%	435 nm	40 nm
Emitter	> 90%	655 nm	15 nm
	Average Reflection	Reflection Band	Transmission Band
Dichroic	> 98%	327 - 488 nm	515 - 850 nm

* Bandwidth is the minimum width over which the average transmission exceeds the specified passband transmission; the nominal full-width-at-half-maximum (FWHM) is approximately the Bandwidth + 1% of the Center Wavelength.
