Hello Jens,

You would need a large amount of pixels to digitally resolve your  
images with such low magnification, and a large chip to collect light  
from fluorescence. That is a difficult thing to find. One interesting  
color imaging technique is made by a company called Foveon: http:// 
www.foveon.com/ They make a 14 megapixel 3 layer CMOS chip (called  
Foveon X3) that is 21x14 mm, that might be useful to you in this  
regard. Here is a link to the PDF: http://www.foveon.com/files/ 
F13_image_sensor_Product_Flier_RevD.pdf

I have no affiliation with the company, and have not even tried it  
out, but am intrigued by the technology.

You could also get a normal monochrome CCD Camera with an electronic  
LCD trigger, like Diagnostic Instruments SPOT RT Slider from Visitron  
GmbH or QImaging Regina with a trigger from Chromaphor.

Same disclaimer as above.

Good luck on your search!

Pete

Dear colleagues,

we are looking for suitable illumination & camera/s for our Leica Z6
MacroFluo. It is used for both fluorescence and absorption contrast
samples.

Has anybody out there experience with LED illumination in combination
with a monochrome camera to generate 'true color' images?

Your advice is welcome, commercial replies off list, please.

Thank you, jens
