A thin section was cut through a rose stem and viewed under a polarised light microscope. Introducing a retarder into the light-path interferes with the light to give the colours seen (which have not been altered in Photoshop). The individual cells in the centre of the stem can clearly be seen.
Silver coloured high quality metal keyrings with a colourful dye-sublimation printed picture of a microscope image on one side that gives a durable and scratch resistant finish.
Keyrings measure 42x25mm (measured without including ring).
Supplied in a presentation box with a label describing the image.
