MultiBandpass Filter 470/545/635

The MultiBandpass Filter 470/545/635 delivers precise spectral transmission across three critical wavelengths—470 nm (blue), 545 nm (green), and 635 nm (red)—making it ideal for multi-color fluorescence microscopy, flow cytometry, and RGB imaging applications.

Key Features

• Triple-band transmission: Optimized passbands at 470, 545, and 635 nm with steep edge transitions
• High transmission efficiency: >90% peak transmission in each passband for maximum signal throughput
• Deep blocking: OD 4+ rejection between bands and in stop regions to eliminate crosstalk
• Durable hard coatings: Ion-assisted deposition ensures long-term stability in demanding lab environments
• Precision substrate: High-quality optical glass with λ/4 surface flatness for minimal wavefront distortion

Applications

• Multi-color fluorescence microscopy (DAPI/GFP/mCherry, CFP/YFP/RFP)
• Flow cytometry and cell sorting with multiple fluorophores
• RGB color separation in machine vision and spectral imaging
• Confocal and widefield microscopy emission filtering
• Automated imaging systems requiring simultaneous multi-channel detection

Technical Specifications

Each filter is manufactured to tight tolerances and ships with a certificate of conformance. Compatible with standard 25 mm filter cubes and holders. Custom sizes and wavelength combinations available upon request.
