MultiBandpass Filter 837/1064

Dual-Band Precision for NIR Applications

The MultiBandpass Filter 837/1064 delivers simultaneous transmission at two critical near-infrared wavelengths—837 nm and 1064 nm—making it ideal for multi-laser fluorescence, Raman spectroscopy, and dual-wavelength imaging systems.

Key Features

• Dual-band transmission: High throughput at 837 nm and 1064 nm with steep edge transitions
• Deep blocking: OD 4+ rejection across UV, visible, and intermediate NIR regions
• Rugged hard-ion coating: Durable, scratch-resistant surface for demanding lab environments
• Precision-polished substrates: Low wavefront distortion for imaging and beam-steering applications
• Standard 25 mm diameter: Drop-in compatibility with most filter wheels and optical mounts

Applications

Engineered for fluorescence microscopy with dual NIR dyes, multi-laser confocal systems, Raman spectroscopy with 785 nm or 1064 nm excitation, and NIR imaging workflows requiring simultaneous detection at both bands.

Specifications

Available in 25 mm diameter with custom sizes on request. Substrate: fused silica or equivalent low-autofluorescence glass. Coating: hard dielectric multi-layer stack optimized for angle-of-incidence ≤ 10°. Typical transmission >90% in passbands, blocking OD >4 from 200–1200 nm (excluding passbands).
