NIGHTSEA® Fluorescence Viewing Systems
NIGHTSEA® and Electron Microscopy Sciences... Moving Forward Together
Electron Microscopy Sciences is pleased to announce the acquisition of NIGHTSEA, a proven innovator of complete and economical solutions - light sources and matched filters - for viewing and imaging fluorescence at scales from macro to micro, featuring the NIGHTSEA Stereo Microscope Fluorescence Adapter.
Product Notice August 2026
Up to now we have offered what we call the ‘standard’ base with simple on/off operation, and a separate intensity control option, which we called DIM. As of August 2026 all systems will include the intensity control feature.
The intensity control does not degrade performance compared to the on/off switch. When first energized the unit comes on at the same full power level, while further rotation of the rotary knob reduces the intensity to about 30% of maximum.
Why would you want to reduce the excitation intensity, given that usually you want as much fluorescence response as you can get? There are situations for which it can be beneficial to reduce the excitation, and you can read about them in this article.
