Product Introduction – 10nm Bandwidth Series Narrowband Bandpass Interference Filter (OD5, High Blocking & High Transmission)
Overview
The 10nm Bandwidth Series narrowband bandpass interference filter is a high-performance optical component designed for precise wavelength selection. With a full width at half maximum (FWHM) of 10nm, this filter transmits light within a very narrow spectral range while blocking all other wavelengths. Featuring an optical density (OD) of 5 (OD5) in the rejection band, it provides excellent blocking efficiency (99.999% attenuation), combined with high transmission (typically >90%) at the target wavelength. Manufactured using advanced ion-assisted deposition (IAD) or magnetron sputtering technology, these filters offer superior environmental stability, sharp edge transitions, and long-term reliability.
Key Features
1. Narrow Bandwidth (10nm FWHM)
-
Precisely selects a 10nm spectral window, enabling high-resolution spectral analysis and laser line purification.
-
Ideal for applications requiring strict wavelength discrimination, such as fluorescence microscopy, Raman spectroscopy, and LiDAR.
2. High Blocking Depth (OD5)
-
Achieves optical density ≥5 (OD5) across the entire rejection band, corresponding to >99.999% light blocking.
-
Effectively eliminates out-of-band stray light and background noise, ensuring superior signal-to-noise ratio (SNR).
3. High Transmission (T>90% at peak)
-
Peak transmittance typically exceeds 90%, maximizing optical signal throughput and minimizing power loss.
-
Balances high blocking with high transmission for demanding optical systems.
4. Steep Edge Roll-Off
-
Transition width from passband to rejection band is typically <1% of center wavelength (CW), providing excellent spectral contrast.
5. Durable Construction
-
Substrate materials: high-quality optical glass (e.g., B270, fused silica) or UV-grade quartz.
-
Hard-coated dielectric layers resist humidity, temperature cycling, and mechanical abrasion.
-
Compliant with environmental durability standards (MIL-C-48497, Telcordia GR-1221-CORE).
