MultiBandpass Filter 520/580/670

Triple-Band Fluorescence Filter for Multi-Color Imaging

The MultiBandpass Filter 520/580/670 delivers simultaneous transmission across three precisely defined spectral bands—520 nm, 580 nm, and 670 nm—enabling efficient multi-color fluorescence microscopy and imaging workflows. Engineered with hard-coated dielectric layers, this filter provides high transmission in each passband while maintaining steep edge transitions and deep blocking between bands.

Key Features

• Triple-band transmission: Optimized for green (520 nm), yellow-orange (580 nm), and red (670 nm) fluorophores
• High optical density blocking: OD >5 rejection between passbands minimizes crosstalk
• Steep edge transitions: Ensures clean spectral separation for multi-label experiments
• Durable hard coatings: Resistant to humidity, temperature cycling, and routine cleaning
• Low autofluorescence substrate: Reduces background signal in sensitive detection systems

Applications

Ideal for multi-color fluorescence microscopy, flow cytometry, live-cell imaging, immunofluorescence assays, and spectral unmixing workflows. Compatible with common fluorophore combinations including FITC/TRITC/Cy5, GFP/mCherry/Alexa Fluor 647, and similar multi-label panels.

Specifications

Available in standard 25 mm diameter format with custom sizes upon request. Each filter is individually tested and ships with a spectral transmission curve. Designed for integration into filter cubes, filter wheels, and automated imaging platforms.
