About This Filter
Our 350nm bandpass filter delivers precise ultraviolet (UV) wavelength selection with exceptional blocking. The narrow 20nm bandwidth ensures only 348-354nm light passes, while eliminating 99.99% of light from 200-1000nm—critical for UV applications requiring minimal background interference.
Key Benefits
- High average transmittance (>85%) in 348-354nm range
- Ultra-steep blocking (<0.01% T) across 200-1000nm
- Stable 350nm center wavelength (±2nm) for consistent results
- Durable construction withstands UV exposure and handling
Applications
- UV Spectroscopy: Isolates 350nm excitation/emission lines with minimal noise in chemical analysis
- Fluid Analysis: Enhances detection of UV-absorbing compounds in water/chemical testing
- Biomedical Research: Enables precise UV light delivery for cellular studies and fluorescence assays
