MultiBandpass Filter 445/525/598/710

Four-Band Precision Filtering for Multi-Color Fluorescence and Spectroscopy

The MultiBandpass Filter 445/525/598/710 delivers simultaneous transmission across four discrete spectral bands—445 nm, 525 nm, 598 nm, and 710 nm—enabling efficient multi-channel imaging and detection in a single optical element. Engineered for fluorescence microscopy, flow cytometry, and multi-wavelength spectroscopy, this filter eliminates the need for filter-wheel switching and accelerates data acquisition in complex assays.

Key Features

• Quad-band transmission: Optimized passbands at 445, 525, 598, and 710 nm for common fluorophores (DAPI, GFP, RFP, Cy5.5)
• High transmission efficiency: >90% peak transmission in each band for maximum signal throughput
• Deep blocking: OD 5+ rejection between bands to minimize crosstalk and background
• Durable hard-coated surface: Ion-assisted deposition ensures long-term stability in high-humidity and high-power environments
• Precision-polished substrates: λ/4 surface quality for diffraction-limited imaging performance

Applications

• Multi-color fluorescence microscopy (live-cell and fixed-sample imaging)
• Flow cytometry and cell sorting with multiple fluorescent markers
• Spectral unmixing and FRET analysis
• High-content screening and automated imaging platforms
• NIR-extended detection workflows (710 nm band)

Technical Specifications

Available in standard 25 mm and 50 mm round formats, with custom sizes and rectangular geometries available on request. All filters ship with spectral performance data and are backed by our standard warranty. Compatible with most commercial microscope cubes, filter wheels, and optical mounts.

Ideal for labs requiring repeatable, high-fidelity multi-channel detection without the complexity of sequential filter changes.
