Product Family Description

>OD 4.0 Rejection of Laser Wavelength from 355nm to 1064nm
Broad Transmission Range
OD 6.0 Notch Filters Also Available
Low Cost Alternative to Rugate Notch Filters

TECHSPEC® OD 4.0 Notch Filters are low-cost alternatives to Rugate Notch Filters. TECHSPEC OD 4.0 Notch Filters feature narrow rejection bands of just ±2.5% of the center wavelength while offering greater than 99% reflection of the laser wavelength. These optical filters are hard coated to guarantee performance that will not degrade with time, temperature, or humidity. Each optical filter has been mounted in a black anodized ring that has been engraved to ease filter handling, identification, and orientation.

Note: These filters are optimized for high spectral performance rather than high Laser Induced Damage Thresholds (LIDT). A typical LIDT for these filters is 1 J/cm² @ 532nm, 10ns. Please contact us if you require a filter with a higher LIDT value.

All mounted TECHSPEC® Optical Filters have an arrow on the side of the mount that points to the filter-coated surface for quick reference. Filter oriented such that arrow points to filter coated surface S1. Anti-reflective (AR) coating is applied to S2.
