Technische beschrijving Infrared glasses
We geeks are always striving to make it clear to ordinary mortals how incredibly exciting science can be. Would you have thought that every living plant glows? How can you not be excited about that! The catch is that you can't see this phenomenon, chlorophyll fluorescence, with the naked eye. These glasses give you the right perspective to actually see the glow with your own eyes.
Glowing Plants
As everyone knows, plants absorb light, which they need for photosynthesis. However, in this process, they also emit weak long-wavelength light. This chlorophyll fluorescence is usually not visible because of the rest of the light spectrum.
How does it work?
It's actually quite simple, the glasses contain a color filter starting at 700nm. This filters all visible light except for a small portion of the spectrum, the barely visible red that transitions into infrared. So we only see the red light emitted by the plants.
What is it good for?
Uh, we can see plants glow! Can it get any better? But of course, it has a practical use as well, for example, for biologists or other plant enthusiasts. By analyzing the chlorophyll fluorescence, the photosynthesis activity can be determined. This way, you know if the plant is healthy or if it is suffering from external influences or, for example, nutrient deficiency.
Important: The infrared glasses are not sunglasses and you should never look at lamps or the sun itself! However, the glasses can be converted into sunglasses with the included replacement lenses. :)
Also, be careful when dealing with all the normals who have no sense of science. Staring too long with opaque glasses in public parks could lead to misunderstandings - even if you just want to admire the chlorophyll fluorescence.
