Laser Line Interference Filters
Laser line filters are intended for either isolation or simulation of laser lines. The major laser lines of interest are listed here but if you need a filter for a different laser type please call and we will be glad to supply you with a quote. Laser line filters are offered in three different bandwidths: 1nm, 3nm and 10nm.
All our interference filters are supplied with an individual spectrophotometer trace.
