MultiBandpass Filter 430/490/590/900

Quad-band precision filter for multi-wavelength fluorescence and spectroscopy

The MultiBandpass Filter 430/490/590/900 delivers simultaneous transmission across four critical wavelengths—430 nm, 490 nm, 590 nm, and 900 nm—enabling efficient multi-channel imaging and detection in a single optical element. Engineered with hard-coated dichroic layers, this filter provides sharp band edges, high transmission efficiency, and exceptional out-of-band blocking for demanding research applications.

Key Features:

• Four discrete passbands optimized for UV-visible-NIR workflows
• High transmission (>90% typical) with steep spectral transitions
• Deep blocking (OD 4–6) between bands to minimize crosstalk
• Durable hard-coated surface for long-term stability in lab environments
• Compatible with fluorescence microscopy, flow cytometry, and multi-laser systems

Applications:

• Multi-color fluorescence imaging with DAPI, GFP, mCherry, and NIR dyes
• Flow cytometry and cell sorting with multiple excitation sources
• Spectroscopy and Raman systems requiring discrete wavelength isolation
• Machine vision and industrial inspection across broad spectral ranges

Ideal for researchers and OEMs seeking to streamline optical paths and reduce component count without sacrificing spectral purity. Available in standard 25 mm diameter; custom sizes and coatings available upon request.
