Fluorescence filter sets
Wide-field Fluorescence Filters
These filter and dichroic mirror configurations are available when the light path is oriented towards the fluorescence filter wheel and Andor Zyla camera on the right-hand port.
Quad-band filters for fast switching to the Zyla Camera. High speed but risk of cross-talk.
Filter ID | Excitation Wavelength | Dichroic Mirror | Emission Filter (in quad) | Example Fluorophores |
|---|---|---|---|---|
| DAPI | 385 nm | 86012v2 Dapi/FITC/TxRed/Cy5 | ~ 455nm - 485nm | DAPI, Hoechst |
| FITC | 470 nm | 86012v2 Dapi/FITC/TxRed/Cy5 | ~ 510nm - 545nm | GFP, FITC |
| TxRed | 550 nm | 86012v2 Dapi/FITC/TxRed/Cy5 | ~ 590nm - 630nm | RFP, mCherry |
| Cy5 | 635 nm | 86012v2 Dapi/FITC/TxRed/Cy5 | ~ 670nm - 740nm | Cy5 |
Sedat quad-band dichroic and single-band emission filters for slower switching. Lower speed but reduced cross-talk between channels.
Filter ID | Excitation Wavelength | Dichroic Mirror | Emission Filter (in wheel) | Example Fluorophores |
|---|---|---|---|---|
| DAPI | 385 nm | 89000 Sedat Quad | 435 - 485 | DAPI, Hoechst |
| GFP | 470 nm | 89000 Sedat Quad | 500 - 550 | GFP, FITC |
| RFP | 550 nm | 89000 Sedat Quad | 590 - 650 | RFP, mCherry |
| Cy5 | 660 nm | 89000 Sedat Quad | 662 - 737 | Cy5 |
| CFP | 470 nm | 89002 CFP/YFP | 460 - 500 | CFP |
| eYFP | 500 nm | 89002 CFP/YFP | 520 - 550 | YFP |
iSIM Filters
The iSIM has the following quad-band dichroic and emission filter in its scan head. The emission filter is Chroma part number 88100bs from Pinkel set 88000v2.
