532nm Ultra-Narrow Bandpass Filter for Life Sciences & Fluorescence
OD6+ Deep Blocking | < 3nm FWHM | Unmatched Signal-to-Noise Ratio
- Extreme Contrast for Fluorescence: Precision-engineered to transmit the 532nm excitation wavelength while aggressively blocking out-of-band noise up to OD6, guaranteeing crisp, high-contrast imaging for FITC/GFP fluorophores.
- Ultra-Narrow Bandwidth: With a Full Width at Half Maximum (FWHM) as narrow as 2nm - 3nm, it perfectly isolates your target signal and prevents spectral crosstalk in multiplexing instruments.
- Dense Dielectric Durability: Manufactured with high-density Ion-Assisted Deposition (IAD), ensuring zero wavelength shift under temperature fluctuations and a prolonged lifespan in rigorous laboratory environments.
- Global Export Ready: 100% Germanium-free and ITAR-free. Designed exclusively for civilian biomedical and analytical instrumentation, guaranteeing a secure and uninterrupted global supply chain.

Product Overview
Optimized for Fluorescence & PCR
In life sciences, every photon counts. Our 532nm ultra-narrow filters are the core optical engine for fluorescence microscopy, flow cytometry, and real-time PCR instruments. By completely suppressing excitation light leakage and background autofluorescence, we empower your sensors to detect the faintest emission signals with absolute certainty.
Zero-Shift Dielectric Coating
We don't compromise on coating density. Utilizing advanced IAD technology, we deposit hundreds of ultra-thin layers to create a "solid-state" filter that is impervious to moisture and thermal variations. This means the 532nm center wavelength remains locked in place, ensuring your instruments deliver consistent, repeatable test results year after year.
Compliant B2B Supply & Assembly
Navigating global optics procurement shouldn't be risky. We focus strictly on B2B civilian applications. Free from export-restricted materials like Germanium, our supply chain is transparent and stable. Whether you need bare filters or custom optical sub-assemblies for your next-gen medical devices, we deliver without the red tape.
Metrology & Performance Reports
Figure 1: Ultra-Narrow Transmittance & OD6 Blocking Curve
Target Wavelength: 532nm CWL | Application: Fluorescence Excitation/Emission
The spectrophotometer data reveals a needle-like transmission spike precisely at 532nm, seamlessly transitioning into a flatline of OD6+ blocking across the detector’s sensitive range (up to 1000nm).
Performance Validation & Metrology Analysis
- Testing Equipment: Ultra-High Resolution UV-VIS-NIR Spectrophotometer.
Target Wavelength: 532nm (Optimized for Nd:YAG lasers and green-excited fluorophores).
Performance Index: Peak Transmittance > 85% & Out-of-band Blocking ≥ OD6.
Optical Edge: The “square-wave” spectral profile guarantees razor-sharp cut-on and cut-off edges, crucial for separating closely spaced fluorophore emission peaks.
Benefit: Dramatically lowers the limit of detection (LOD) in your bio-analytical instruments, giving your end-users unprecedented imaging clarity and diagnostic accuracy.
