Product Family Description

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.

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.
