Two-photon excitation microscopy is a fluorescence imaging technique that allows imaging of living tissue up to a very high depth, that is up to about one millimeter. Being a special variant of the multiphoton fluorescence microscope , it uses red-shifted excitation light which can also excite fluorescent dyes . However for each excitation, two photons of the infrared light are absorbed. Using infrared light minimises scattering in the tissue. Due to the multiphoton absorption the background signal is strongly suppressed. Both effects lead to an increased penetration depth for these microscopes. However, the resolution remains diffraction-limited . Two-photon excitation can be a superior alternative to confocal microscopy due to its deeper tissue penetration, efficient light detection and reduced phototoxicity .

I was expecting better. Image looks faded and the houses on the image are near folded underneath. Likely throw this in the bin.

My partner proposed on our first holiday and we ate tonnes of garlic bread. This was a perfect reminder. The magnet is strong and the quality and value for money excellent. Exactly as pictured. Superb.

Excellent all round, the printing is great and the magnet is streamlined, not chunky. The actual magnet is very strong. Very good quality and the price is low. Absolutely fantastic! Crisp, bright, clean.
