MultiBandpass Filter 470/575

Dual-Band Fluorescence Filter for Multi-Color Imaging

The MultiBandpass Filter 470/575 delivers precise spectral transmission at two distinct wavelengths—470 nm and 575 nm—enabling simultaneous dual-channel fluorescence detection in microscopy, flow cytometry, and multi-color imaging applications.

Key Features

• Dual-band transmission: High-efficiency passbands centered at 470 nm (blue) and 575 nm (yellow-green) for multi-fluorophore workflows
• Steep edge transitions: Minimizes spectral crosstalk between channels for clean signal separation
• Hard-coated ion-assisted deposition: Ensures long-term stability in high-humidity and high-intensity environments
• Low autofluorescence substrate: Reduces background noise for improved signal-to-noise ratio
• Precision-polished surfaces: Maintains wavefront quality for diffraction-limited imaging

Applications

• Multi-color fluorescence microscopy (DAPI/FITC, CFP/YFP combinations)
• Flow cytometry and cell sorting with dual-label detection
• Live-cell imaging and time-lapse studies
• Immunofluorescence assays requiring simultaneous detection
• Spectral unmixing and ratiometric imaging

Technical Advantages

Engineered for researchers who demand repeatable performance across imaging sessions, this filter supports quantitative fluorescence analysis with minimal drift. Compatible with standard filter cubes and emission wheels, it integrates seamlessly into existing optical setups.

All filters ship with individual spectral certification and are backed by our standard warranty for research-grade optical components.
