Notch Filters

Product Name : Notch Filters

Description :

● The stunning StopLine E-grade notch filters offer high transmission over ultra-wide passbands (UV to 1600 nm)
● Deep laser-line blocking for maximum laser rejection (OD > 6)
● 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

StopLine deep notch filters rival the performance of holographic notch filters but in a less expensive, more convenient, and more reliable thin-film filter format (U.S. Patents No. 7,123,416 and No. 9,354,370). 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: our StopLine E-grade thin-film 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 near-infrared (1600 nm). They are especially suited for optical systems addressing multiple regions of the optical spectrum (e.g., UV, Visible, and Near-IR), and for systems based on multiple detection modes (e.g., fluorescence, Raman spectroscopy, laser-induced breakdown spectroscopy, etc.).
