NIGHTSEA (10 products in this category)

NIGHTSEATM provides practical and economical solutions enabling researchers to use fluorescence as method to gain scientific information. NIGHTSEATM equipment has been successfully used in laboratories around the world for visualizing fluorescent proteins at both, micro and macro scales for screening/sorting transgenic genotypes (C. elegans, drosophila, mouse, rat, zebrafish, plants,…), using fluorescence to aid dissection, injection and many other scientific applications.


NIGHTSEA’s Stereo Microscope Fluorescence Adapter extends fluorescence to
standard routine stereo microscopes with no disassembly or modification of your
microscope needed. It is a modular system with 5 excitation/emission combinations
to cover a broad optical spectrum.

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

NEW – now also for Keyence VHX Series:
The NIGHTSEA Stereomicroscope Fluorescence Adapter is now also available for the Keyence VHX microscope series incl. VHX-5000 and VHX-6000. For this microscope model, a special emission filter holder was developed.

Band-pass filter for GFP emission:
The new band-pass barrier filter is for use with the Royal Blue excitation source (ESFA-RB) and transmits the green part of the spectrum from approx. 500 to 560nm. 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 filter is also useful for applications in which background autofluorescence reduces viewing contrast.

NIGHTSEATM Flashlight Solutions:
NIGHTSEATM further developed a portable battery-operated Dual Fluorescence Protein flashlight  (EDFP-1) for fluorescence screenings useful in your lab/animal facility or even in the open field and the smaller BlueStarTM flashlight with single wavelength for GFP exciation.

NIGHTSEA™ Stereo Microscope Fluorescence Adapter

NIGHTSEA™ Stereo Microscope Fluorescence Adapter, with Filter

NIGHTSEA™'s new Stereo Microscope Fluorescence Adapter adds fluorescence to just about any stereo microscope (or dissecting microscope) with no modification to the microscope itself. The modular design lets you easily switch between several excitation / emission combinations to work with a variety of fluorescent proteins and other fluorophores.

The NIGHTSEA™ comes now with a BNC-connector.

NIGHTSEA™ Stereo Microscope Fluorescence Adapter for Keyence VHX Series, with Filter

The NIGHTSEA™ Stereo Microscope Fluorescence Adapter now adds fluorescence also to the Keyence VHX Series such as the VHX-5000 and VHX-6000 using a similar approach as for the standard version. The modular design lets you easily switch between several excitation / emission combinations to work with a variety of fluorescent proteins and other fluorophores. This system fits on the VH-Z00, VH-Z20, VH-Z50x and VH-Z100 series lenses.

Nightsea Modular White Light Head

NIGHTSEA™ Modular White Light Head

A LED white light head is also available as an illumination option for the Stereo Microscope Fluorescence Adapter. Now if you are using the NIGHTSEA™ system for fluorescence you do not need a separate light source for your white-light work - just exchange the fluorescence excitation light head module for the white-light module in a matter of seconds. Extremely convenient for general illumination and as a focusing aid for fluorescence imaging. Comes with a BNC connector.
NIGHTSEA BlueStar™ Flashlight

NIGHTSEA BlueStar™ Flashlight

The BlueStar flashlight combined with the matched barrier filter glasses is a convenient, powerful tool for exciting fluorescence in many subjects. The BlueStar uses the latest in high intensity LED technology (1W, 440-460nm) combined with specialized optics to produce an ultra-tight, ultra-bright 10-degree beam pattern for maximum excitation of fluorescence.

NIGHTSEA Industry Kit for Keyence VHX-Series incl. Adapter for VH-ZST Objective


The NIGHTSEA Industry Kit has been particularly developed to work with the most commonly used lenses including the VH-ZST lens. The special emission filter is inserted into the in the analyser slot of the VH-ZST lens and an adapter allows for direct coupling of the fluorescence excitation through the VH-ZST light guide for improved fluorescence signals. The kit includes the excitation light source and filters for the 3 wavelengths UV, Violet and Royal Blue.

More colors and kits for single wavelengths will be available soon.
