Notch Filters

These deep notch filters rival the performance of holographic notch filters but are in a less expensive, more convenient and reliable thin-film filter format. Notch filters are ideal for applications including Raman spectroscopy, laser based fluorescence instruments, and biomedical laser systems. The filters have a high damage threshold and proven reliability. Rejected light is reflected, for easy alignment and best stray-light control. The StopLine E-grade notch filter offers high transmission over ultra-wide passbands (UV to 1600nm). The deep laser-line blocking (OD>6) gives maximum laser rejection.

Multi-notch filters block multiple laser lines. These include dual-, triple- and even quadruple-notch filters for a variety of multi-laser instruments. These filters have a 10-year guarantee and are available on a 30-day free trial.
