BP637-1 Bandpass Filter(CWL=637nm,FWHM=1nm)

The BP637-1 is a precision bandpass filter engineered for high-performance fluorescence imaging and spectroscopy applications requiring ultra-narrow spectral isolation at 637 nm.

Key Specifications:

• Center Wavelength (CWL): 637 nm
• Full Width at Half Maximum (FWHM): 1 nm
• Optical Density (OD): >4 blocking
• Transmission: High-efficiency dielectric coating
• Substrate: Precision-grade optical glass

Applications:

• Red fluorescence microscopy and multi-channel imaging
• Raman spectroscopy signal isolation
• Laser line cleanup and wavelength selection
• Flow cytometry and cell sorting systems
• Confocal microscopy and super-resolution imaging

Performance Features:

• Ultra-narrow 1 nm bandwidth for exceptional spectral selectivity
• OD >4 out-of-band blocking minimizes crosstalk and background noise
• Hard dielectric coatings ensure long-term stability and durability
• Optimized for integration into fluorescence filter cubes and optical assemblies
• Ideal for demanding applications requiring precise wavelength discrimination in the red spectrum

Each filter is individually tested and verified to meet published spectral specifications. Transmission curves and test data available upon request.
