LED Array Modules : 445nm & 505nm

CoolLED is pleased to announce two new LED Array Modules (LAMs) for the precisExcite LED source. These are at 445nm (CFP) and 505nm (YFP) wavelengths. These complement the existing wavelengths available at 400, 465, 525, 595 and 635nm. Full details and optimal filter data can be found at the precisExcite website.

precisExcite uses high-power LED arrays which benefit from active cooling to achieve precise thermal control. This ensures maximum intensity and stability throughout their lifetime. CoolLED is constantly monitoring LED availability and will continue to introduce new wavelengths as they become available.

Dual Staining - GFP & mCherry

Dual staining applications such as GFP + mCherry are becoming common procedure. The ability to control the intensity of individual wavelengths independently means that excitation can be balanced such that one strong fluorophore is not saturating a camera, whilst another is seen as too weak. ND filters and shutters are not required when using precisExcite for this procedure.

The precisExcite unit can be specifically configured for this application. Excitation filters can be integrated within the system and an optimised double dichroic supplied. This mean that there will be no moving parts, resulting in vibration-free microsecond switching.

Please contact CoolLED if you are interested in further details on this application.

American Society for Cell Biology meeting,
Washington DC, 2-4 December

        CoolLED will be exhibiting at the ASCB meeting at the beginning
        of December. This will be an opportunity to see precisExcite
        units and appreciate the level of control and stability that is
        now possible for your fluorescence excitation. CoolLED will be
        at Booth 1045.
