MultiBandpass Filter 450/660（OD5@700-1100nm）

Dual-Band Precision for Fluorescence & Spectroscopy

The MultiBandpass Filter 450/660 delivers simultaneous transmission at 450 nm (blue) and 660 nm (red) wavelengths, enabling multi-color fluorescence imaging, dual-channel spectroscopy, and advanced microscopy workflows. Engineered with hard-coated ion-beam-sputtered (IBS) dielectric layers, this filter provides exceptional spectral purity and OD5 (>99.999%) blocking from 700–1100 nm to eliminate NIR crosstalk and autofluorescence.

Key Features

• Dual Passbands: Optimized transmission at 450 nm and 660 nm for multi-color detection
• OD5 Blocking: Superior rejection (>99.999%) across 700–1100 nm to protect detectors and reduce noise
• Hard IBS Coatings: Durable, scratch-resistant surface for long-term lab use
• High Transmission: >90% peak transmission in both passbands for maximum signal throughput
• Steep Edges: Sharp spectral transitions for precise channel separation

Applications

• Multi-color fluorescence microscopy (DAPI/Cy5, CFP/mCherry)
• Dual-wavelength spectroscopy and photometry
• Flow cytometry and cell imaging
• Optogenetics and photobiology research
• NIR-blocking applications in visible-range detection
