MultiBandpass Filter 1210/1300/1450/1650

Precision Four-Band Optical Filter for NIR/SWIR Applications

The MultiBandpass Filter 1210/1300/1450/1650 delivers simultaneous transmission across four critical near-infrared and short-wave infrared wavelengths—1210 nm, 1300 nm, 1450 nm, and 1650 nm—enabling multi-channel spectroscopy, imaging, and sensing in a single optical element.

Key Features

• Quad-band transmission: Optimized passbands at 1210, 1300, 1450, and 1650 nm for parallel wavelength detection
• High spectral purity: Steep edge transitions and deep blocking between bands minimize crosstalk
• Rugged hard-coated surface: Durable ion-assisted deposition ensures long-term stability in lab and field environments
• Low wavefront distortion: Precision-polished substrates maintain beam quality for imaging applications
• Custom configurations available: Bandwidth, blocking range, and substrate options tailored to your workflow

Applications

• NIR/SWIR spectroscopy and hyperspectral imaging
• Telecommunications component testing and wavelength division multiplexing
• Moisture and chemical analysis in process monitoring
• Multi-wavelength fluorescence and Raman systems
• Semiconductor inspection and quality control

Designed for researchers and engineers who demand repeatable performance across multiple infrared bands, this filter integrates seamlessly into optical systems requiring simultaneous multi-wavelength detection without the need for filter wheels or sequential switching.
