3 ports Fluorescence Mini Cube - Single Fluorophore
3 ports Fluorescence Mini Cube - Single Fluorophore
Voici une description courte popur vouir ce que ca donne seulement... Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor
Single excitation band fiber photometry measurements use an FMC with 3 ports: one port for the excitation light, one for the fluorescence detection, and one to connect to the sample. The cube has a dichroic mirror to let the excitation light through and separate the fluorescence emission and narrow bandpass filters to limit the excitation or fluorescence spectrum. E stands for fluorescence excitation, F for fluorescence, and S for the sample port on the cube's schematic. Currently, only Green Fluorophore (GFP-like) configurations or Red Fluorophore (RFP-like) are offered. Still, the filter set can be customized for other fluorophores on request.
The Intensity Adjustment Ring on the 460-490 nm LED light source reduces the source power below the LED driver's range if needed for low-power fiber photometry experiments.
Compared to Fluorescence Mini Cubes with only FC connectors on all ports, the ones with integrated photodetectors provide a 100% better signal-to-noise ratio (30% signal increase and a 40% noise reduction). Moreover, the versions where LEDs are integrated as well reduce the number of optical connections and the system’s overall footprint.
