Red, green and blue lasers
The red (635 nanometer), green (532 nanometer) and blue (488 nanometer) lasers all have different wavelengths and thus get used for different tasks. The lasers in this class sell for between $2,495 and $11,995.
699 Ring Dye laser
A 699 Ring Dye laser. It is used for spectroscopy, or the study of how atoms emit light. Semiconductor manufacturers require these tools to test their products. The ring laser can be tuned for wavelengths of 300 to 900 nanometers.
