NIGHTSEA Fluorescence Adapter for Stereomicroscopes(5)
NIGHTSEA’s Stereo Microscope Fluorescence Adapter extends fluorescence to standard routine stereo microscopes without disassembly or modification of the microscope. It is a modular system with 5 excitation/emission combinations to cover a broad optical spectrum. The standard emission is provided with long-pass filters.
Bandpass Emission Filter ‘green only’ for eGFP Fluorescence
For eGFP excitation and other fluorophores in this excitation range, a 'green only' bandpass filter with a transmission spectrum of approx. 500-560nm is also available for use with the Royal Blue base unit (SKU: ESFA-RB).
The primary motivation for the green-only emission filter was for the benefit of researchers using GFP in plants, such as Arabidopsis thaliana. Plants contain chlorophyll, which has a distinctive red fluorescence that can sometimes mask the GFP emission. The ‘green only’ filter is also useful for applications in which background autofluorescence reduces viewing contrast.

The NIGHTSEA Stereomicroscope Fluorescence Adapter base unit has been further developed and is also available as a triggerable or dimmable version on request. IMPORTANT: Only one of the two functions can be chosen for a device.
