Laser Line Filters

Laser line Filter is a high precision optical filter with an extremely narrow passband centered on a standard laser wavelength. These optical filters are used to prevent the distortion of measurement signals and to increase image contrast.  They are used to screen out undesirable background radiation and ambient light. These filters have excellent blocking (an optical density of greater than 5.0) from ±1% of the laser wavelength. Custom options - please contact our sales department sales@optosigma.com
