Collection: Mercury Lamp Filter

Mercury vapor lamps are a common type of light source that emit light at specific wavelengths due to the characteristics of mercury vapor. Here are some of the primary wavelengths associated with a mercury light source:

1. Ultraviolet:

   • 185 nm: Often used for germicidal purposes (kills bacteria and viruses).
   • 254 nm: Another germicidal wavelength, very effective at deactivating DNA in microorganisms.

2. Visible Light:

   • 365 nm: Known as "black light," it is near the ultraviolet range and is often used in fluorescence applications.
   • 404 nm (violet)
   • 435 nm (blue)
   • 546 nm (green)
   • 578 nm (yellow-orange)

These wavelengths make mercury vapor lamps useful for various applications including scientific research, fluorescence microscopy, and industrial processes. Each wavelength can be used to excite different materials or chemicals, which then emit their own characteristic light, a process used extensively in spectroscopy.
