Collection: 550nm

Light at 550nm falls within the green spectrum and has applications in various fields, some more prominent than others:

• Visible Light Communication (Li-Fi): While less common than radio waves for data transmission, Li-Fi uses light to transmit information. 550nm (green) is a potential candidate for Li-Fi as it falls within a range detectable by standard photodiodes and offers good balance between signal strength and eye safety. However, this technology is still under development.

• Biotechnology and Research:

  • Fluorescence Microscopy: Similar to other green wavelengths, 550nm light can be a useful excitation source in fluorescence microscopy. Certain fluorescent proteins or dyes used in biological research are excited by this wavelength, allowing scientists to visualize specific structures or processes within cells.

• Traffic Signals: While not as common as amber or red, some traffic light systems might utilize green LEDs with a dominant wavelength around 550nm to create a very clear and bright green signal for drivers.

• Complementary Color Mixing: As with 540nm, 550nm green light can be combined with red light (around 620-750nm) to create various shades of yellow or white light sources, particularly in LED lighting products.
