MultiBandpass Filter 555/660/840

The MultiBandpass Filter 555/660/840 delivers simultaneous transmission at three precisely defined wavelengths—555 nm (green), 660 nm (red), and 840 nm (near-infrared)—engineered for multi-channel fluorescence, spectroscopy, and biomedical imaging applications.

Key Features

• Triple-band spectral isolation: High transmission at 555, 660, and 840 nm with steep edge transitions and deep blocking between bands
• Rugged hard-coated optics: Ion-assisted deposition ensures long-term stability in demanding lab environments
• Optimized for multi-marker workflows: Ideal for simultaneous detection of GFP/RFP/NIR fluorophores or multi-wavelength spectroscopy
• Precision-polished substrates: Low wavefront distortion for high-resolution imaging systems
• Custom configurations available: Tailored bandwidths, blocking ranges, and substrate sizes upon request

Applications

• Multi-channel fluorescence microscopy (GFP, mCherry, Cy7)
• Raman spectroscopy with multi-laser excitation
• Biomedical imaging and phototherapy monitoring
• Flow cytometry and cell sorting
• NIR/visible spectral analysis

Each filter ships with measured transmission data and is backed by our standard quality guarantee. Perfect for researchers requiring repeatable, high-purity spectral performance across visible and near-infrared ranges.
