MultiBandpass Filter 525/635

Dual-Band Precision for Fluorescence and Multi-Color Imaging

The MultiBandpass Filter 525/635 delivers simultaneous transmission at 525 nm and 635 nm, enabling efficient dual-channel fluorescence detection and multi-color imaging workflows. Engineered with hard-coated dielectric layers, this filter provides sharp spectral edges, high transmission in passbands, and deep blocking across UV, visible, and near-infrared regions.

Key Features

• Dual passbands: 525 nm (green) and 635 nm (red) for simultaneous detection
• High transmission: >90% in both passbands for maximum signal throughput
• Deep blocking: OD >5 outside passbands to eliminate crosstalk
• Rugged hard coatings: Resistant to humidity, temperature cycling, and cleaning protocols
• Precision-polished substrates: λ/4 surface quality for minimal wavefront distortion

Applications

• Multi-color fluorescence microscopy (GFP/mCherry, FITC/Cy5)
• Flow cytometry and cell sorting
• Confocal and widefield imaging systems
• Spectral unmixing and ratiometric measurements
• Live-cell imaging with dual-labeled probes

Specifications

Available in standard 25 mm diameter, 1 inch square, and custom sizes. Compatible with most microscope filter cubes and optical mounts. All filters ship with spectral transmission data and certificate of conformance.
