OD4.0 Notch Filters

High Transmission with OD4.0 Performance

Our OD4.0 notch filters feature a high optical density of OD4.0, meaning they provide 99.99% attenuation at the center wavelength while maintaining broad transmission outside the blocked range. This ensures that non-targeted wavelengths pass through the pass band with minimal loss, allowing the system to maintain signal strength where needed. This capability is crucial in applications such as Raman spectroscopy and fluorescence microscopy, where isolating a specific wavelength range is critical to the system’s performance.

In addition to exceptional wavelength blocking, Avantier’s OD4.0 notch filters deliver high transmission efficiency across the pass band, maintaining the intensity of transmitted light. Additionally, these filters are designed with robust laser-induced damage thresholds, making them suitable for use in high-power laser systems without the risk of optical damage. This balance between blocking and transmission makes them ideal for sensitive optical systems requiring both durability and precision.

Features of OD 4.0 Notch Filters

These filters are built to withstand fluctuating environmental conditions, including temperature shifts and mechanical stress. Their durability ensures that they perform consistently, even in rugged industrial or outdoor settings. By enduring such conditions without compromising functionality, Avantier’s OD4.0 notch filters offer long-term reliability, making them a robust choice for demanding optical systems.

Avantier’s OD4.0 notch filters are compatible with a wide array of light sources, including lasers, LEDs, and broadband systems. This broad transmission capability allows users to seamlessly integrate these filters into their existing optical systems, effectively isolating desired wavelengths without degrading overall performance.

Enhanced Selectivity by Avantier

The OD4.0 notch filters are engineered with steep edges to provide sharp transitions between blocked and transmitted wavelengths. This design enhances wavelength selectivity, making them especially valuable in applications such as laser-based measurement systems, where precise filtering is critical for accurate results.

Wide-Ranging Applications

From optimizing medical imaging systems to improving the precision of laser-based telecommunications, these filters are invaluable in a variety of fields. Their high optical density, customizable center wavelength and specific wavelength range, along with robust construction, make them a go-to solution for professionals requiring reliable, high-performance optical filtering.
