• Product: Analytical Filters
  • Item No.: 2.6

These filters with narrow bandwidth can offer anoptimum center wavelength for atomic emission lines in both are and spark conditions. These specific lines are chosen to minimize interfaces of coexisting elements.
Our filters are manufactured using Plasma-assisted Deposition (PAD) and Ion-assisted Deposition (IAD) processes. They are abrasion resistant with a long life use for more than 10 years.
All offer excellent out-of-band blocking exceeding 6 OD which provides high signal-to-noise.
