MultiBandpass Filter 486/656.3

Dual-Band Precision for Fluorescence & Spectroscopy

The MultiBandpass Filter 486/656.3 delivers simultaneous transmission at 486 nm (blue) and 656.3 nm (H-alpha red), making it ideal for multi-channel fluorescence microscopy, dual-excitation spectroscopy, and hydrogen-alpha imaging applications.

Key Features

• Dual-band transmission: High-efficiency passbands centered at 486 nm and 656.3 nm
• Steep edge transitions: Minimizes crosstalk and maximizes spectral purity between channels
• Rugged hard-coated optics: Durable ion-assisted deposition for long-term stability in lab environments
• Low autofluorescence: Optimized substrate and coating design reduce background signal
• Precision-mounted: Ready for integration into filter wheels, microscope cubes, and optical assemblies

Applications

• Multi-color fluorescence microscopy (DAPI/Cy5, GFP/mCherry workflows)
• Dual-excitation spectroscopy and Raman imaging
• Hydrogen-alpha astrophotography and solar observation
• Flow cytometry and high-content screening
