BP380-4 Bandpass Filter(CWL=380nm,FWHM=4nm)

The BP380-4 is a precision bandpass filter engineered for high-performance fluorescence imaging and spectroscopy applications requiring ultra-narrow spectral isolation at 380 nm in the UV-visible spectrum.

Key Specifications:

• Center Wavelength (CWL): 380 nm
• Full Width at Half Maximum (FWHM): 4 nm
• Optical Density (OD): >4 blocking
• Transmission: High-efficiency dielectric coating
• Substrate: Precision-grade UV-transmitting optical glass

Applications:

• UV fluorescence microscopy and multi-channel imaging
• Raman spectroscopy signal isolation
• UV laser line cleanup and wavelength selection
• Flow cytometry and cell analysis systems
• Photochemistry and photophysics research

Performance Features:

• Ultra-narrow 4 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 UV applications requiring precise wavelength discrimination

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