Global Rainbow 2016

Global Rainbow

Yvette Mattern’s Global Rainbow is a beautiful, highly emotional piece of art.

A new set of technical equipment facilitates future installations. The Global Rainbow is made from 7 highly collimated, low divergence, powerful laser beams. The colors of the laser beams (Red, Orange, Yellow, Green, light Blue, dark Blue, Purple) reflect Yvette Mattern’s choice.

The laser output power of each of the units is similar: this reflects the power distribution of natural rainbows (identical power in each wavelength band).

The colors are composed from primary colors as close as possible to the desired color. Because no complementary colors are used the resulting colors look very homogeneous.

The entire set consists of 7 separate laser units, one for each color. The units have identical dimensions. They are independent of each other and can be arranged in any desired manner.

Rainbow laser power: 118,400 mW

Rainbow wavelengths:

  • Red: 638 nm
  • Orange: 638 nm / 577 nm mixed
  • Yellow: 677 nm / 445 nm mixed
  • Green: 532 nm / 462 nm mixed
  • Light Blue: 488 nm / 462 nm mixed
  • Dark Blue: 445 nm
  • Purple: 638 nm / 445 nm mixed
