Prizmatix has released an ultra-high-power 460nm light-emitting diode (LED) for fluorescence microscopy.
The ultra-high-power LED provides an almost 10-fold increase of power in comparison with similar high-power LED devices, according to the company.
The new LED can replace lasers and lamps in many power-demanding applications, such as fluorescence microscopy, machine vision and chemical reaction activation.
This latest addition to the modular Optiblocks range provides more than 1W of collimated blue-LED power on its output.
The LED driver supports continuous-wave (CW) or pulsed operation.
The ultra-high-power LED is compatible with Prizmatix's modular Microscope-LED Light Source product range.
It is suitable for single-chip ultra-high-power LED TTL external triggering and for fluorescence excitation.
The LED spectrum can be narrowed by an optional band-pass filter installed inside the head.
Features of the speckle-free instrument include: a stable, precisely adjustable power; a long life (no lamp or laser tube replacement required); and a rapid warm-up time.
Applications include: fluorescence microscopy (Auramine, di-8-ANEPPS, GFP, quantum dots); whole-body imaging; photo activation (PA); the photostimulation of Channelrhodopsin ChR1, ChR2; fluorescence recovery after photo bleach (FRAP); fluorescence in-situ hybridisation (FISH); bio analysis; and machine vision.
Optical specifications are as follows: a wavelength of 460nm; a wavelength range of +/-5nm; a spectrum half width of 27nm; and a collimated optical power output of more than 1,000mW.
