MultiBandpass Filter 450/660（OD3@200-700nm ）

Dual-Band Precision for Fluorescence & Spectroscopy

The MultiBandpass Filter 450/660 delivers simultaneous transmission at 450 nm and 660 nm with deep blocking (OD3 @ 200–700 nm) across the UV-visible spectrum. Engineered for multi-channel fluorescence microscopy, flow cytometry, and dual-wavelength spectroscopy, this filter enables crisp spectral separation without the need for filter-wheel switching.

Key Specifications

• Passbands: 450 nm ± tolerance, 660 nm ± tolerance
• Blocking: OD3 (≥99.9% rejection) from 200–700 nm outside passbands
• Substrate: High-grade optical glass with ion-beam-sputtered hard coatings
• Durability: Resistant to humidity, temperature cycling, and cleaning solvents
• Applications: DAPI/Cy5 imaging, dual-laser excitation, multi-color flow cytometry

Why Choose This Filter?

Eliminate crosstalk between blue and red channels while maintaining high transmission efficiency. The rugged hard-coating process ensures long-term stability in demanding lab environments, and the precision edge steepness minimizes spectral overlap. Ideal for researchers who need repeatable, publication-grade data from multi-fluorophore experiments.

Compatible with standard 25 mm or 1-inch filter cubes. Custom diameters and mounting options available upon request.
