• Blue 470 nm
• Cyan 505 nm
• Green 530 nm
• Amber 590 nm
• Red 627 nm
• Deep-red 660 nm

Additional lights

• UV 385 nm
• Green 530 nm
• Amber 590 nm

GFP measurement

• Royal-blue 447 nm
• Blue 470 nm
• The GFPCam consists of a CCD camera, four to five fixed LED panels (4 + 1 additional, which is not included in the standard setup) and of a filter wheel equipped with up to 7 different emission filters. To be used in all FluorCam configurations.

NDVI measurement

• Deep-red 660 nm
• FAR 740 nm
• High-end option for measuring PAR absorptivity and NDVI reflectance index. It includes 7-position filter wheel, light panel 13 × 13 cm (installed round the camera and mounted with FAR and deep-red LEDs) and a glass filter. PAR-measurement is based on reflectance of plants in near infrared region and in the visible red range of spectrum. NDVI is used as vegetative index for predicting photosynthetic activity. To be used only with FC 800-C/1010, FC 800-C/1010-GPF , FC 800-O/1010 or FC 800-O/2020.

Multicolor fluorescence measurement

• UV 385 nm
• Multicolor Plant Module is High-end option for measuring emission spectra in plants (according to Lichtenthaler and Bushmann). It includes 7-position filter wheel, UV LED light panel (installed round the camera and mounted with 4 UV LEDs), four filters - BLUE (FF01-440/40), GREEN (FF02-520/28), RED (FF01-690/8), FAR-RED (FF01-747/33) and a special software module.
To be used only in the FC 800-C/1010, FC 800-C/1010-GPF, FC 800-O/1010 or FC 800-O/2020. This module cannot be used with the PAR-Absorptivity and NDVI Module in the FC 800-C/1010 or FC 800-C/1010-GPF.

Please note, that not all of the offered LED wavelengths are available for all FluorCam types. For more detailed information please refer to respective FluorCam chapters.

EMISSION FILTERS

All the FluorCam devices are standardly equiped by chlorophyll fluorescence emission filter. For different applications, such as fluorescence proteins detection or multicolor fluorescence detection, the 7-position filterwheel with different filters can be used:

Multicolor fluorescence measurement

• Blue 440/40
