StopLine deep notch filters rival the performance of holographic notch filters but in a less expensive, more convenient, and more reliable thin filter format. These filters are ideal for applications including Raman spectroscopy, laser-based fluorescence instruments, and biomedical laser systems

Semrock introduced a breakthrough invention in thin-film optical filters: the StopLine E-grade notch filters have ultrawide passbands with deep and narrow laser-line blocking. Unheard of previously in a thin-film notch filter made with multiple, discrete layers, these patent-pending notch filters attenuate the laser wavelength with OD > 6 while passing light from the UV well into the NIR. They are especially suited for optical systems addressing multiple regions of the optical spectrum (eg UV, visible and NIR) and for systems based on multiple detection modes.

* The stunning StopLine E-grade notch filters offer high transmission over ultra-wide passbands (UV to 1600nm)
* Deep (OD > 6) laser-line blocking for maximum laser rejection
* High laser damage threshold and proven reliability
* Rejected light is reflected, for convenient alignment and best stray-light control
* Multi-notch filters are available for blocking multiple laser lines
