The abberior RAINBOW Detection pairs high transmission and quantum efficiency with optimal wavelength discrimination. There are no more compromises: you benefit from both maximum signal and full spectral flexibility! The superior detection efficiency of APDs compared to any other photon detector, including PMTs and hybrid detectors, guarantees that you collect as many precious fluorescence photons from your sample as possible.
full contrast, full flexibility
Many eyes see more than one. The MATRIX detector drastically improves signal-to-background ratio, resolution, and dynamic range.
Brings down the light dose on your sample and lables dramatically. Key ingredient for volume and live-cell superresolution.
Growth cone at the tip of the axon of a primary hippocampal neuron at 1 day in vitro. Microtubules (Tuj1, Abberior STAR 580, red) are bundled in the central-domain suggesting a pausing state. The molecular motor myosin IIB (confocal, Alexa488, blue) is enriched at the transition-zone, along the F-actin arcs. In the peripheral domain actin forms bundles in the filopodia (Phalloidin, Abberior STAR 635, green).

3-color STED image of primary hippocampal neurons. Please note the characteristic ~190 nm beta II spectrin periodicity along distal axons (green) which is only visible in the STED image. Labelled structures: beta II Spectrin (green, Abberior STAR635P), Bassoon (red, Abberior STAR580), Actin cytoskeleton (blue, Phalloidin, Oregon Green 488). Imaged with Abberior Expert Line with 595nm and 775nm STED laser. Sample was prepared by Elisa D’Este @ MPIBPC, Göttingen.
with ultra-high transmission
A pair of gradient-coated filters are translated within the RAINBOW Detection in order to freely define the edges of the detection window between 400 and 800 nm. Up to four RAINBOW devices can be installed or upgraded at any time and the fluorescence can be freely distributed between every detector.
Our standard detectors are avalanche photo detectors (APDs), because they have superior quantum efficiencies, up to a factor of two above hybrid detectors. This means that even when the signal levels are low, our APDs still collect plenty of photons for a meaningful image. Typical applications are superresolution STED imaging and experiments with low labeling densities designed to maintain physiological conditions. At the same time, high-signal samples are perfectly taken care of by DYNAMIC PLUS, our dead-time compensation that yields crisp images of brightly labeled samples. This way, confocal imaging is highly improved, too. Of course, you can opt between quantitative analysis of raw data or mathematical post-processing, e.g. deconvolution. Because we always give you genuine photon counts, you remain in full control of your data interpretation. Always.
