MultiBandpass Filter 450/660（OD5@200-900nm）

Dual-Band Precision for Fluorescence & Spectroscopy

The MultiBandpass Filter 450/660 delivers simultaneous transmission at 450 nm and 660 nm with OD5 blocking across 200–900 nm, engineered for multi-channel fluorescence microscopy, dual-excitation spectroscopy, and color-separation imaging workflows.

Key Specifications

• Passbands: 450 nm (blue) and 660 nm (red) with narrow FWHM for spectral purity
• Blocking: OD5 (>99.999% rejection) from 200 to 900 nm outside passbands
• Optical Density: Ensures minimal crosstalk and superior signal-to-noise ratio
• Substrate: High-quality optical glass with hard ion-beam-sputtered coatings
• Durability: Resistant to humidity, temperature cycling, and mechanical wear

Applications

• Dual-fluorophore imaging (DAPI/Cy5, GFP/mCherry combinations)
• Multi-channel confocal and widefield microscopy
• Flow cytometry and plate-reader assays
• Raman spectroscopy with dual-laser excitation
• Machine vision and color-critical inspection systems

Why Choose This Filter?

Achieve clean spectral separation without the need for filter wheels or sequential acquisition. The rugged coating withstands high-power laser exposure and repeated cleaning cycles, while the precision passbands eliminate autofluorescence and stray-light artifacts in demanding research environments.

Designed for: Universities, biotech labs, medical device OEMs, and industrial R&D teams requiring repeatable, publication-grade optical performance.
