Professional LP360 Longpass Filter - UV-A Spectral Control

The LP360 Longpass Filter provides critical wavelength control in the UV-A spectral region, making it essential for applications requiring precise separation of UV radiation from the visible spectrum. This specialized filter is designed for demanding optical systems where UV blocking and broad visible transmission are paramount.

Key Specifications:

  • Cut-on Wavelength: 360nm (T=50%)
  • High Transmission Range: T>90% @ 370-1200nm
  • UV Blocking: OD3 @ 200-350nm
  • Extended Coverage: Full visible to near-infrared spectrum

Applications & Benefits:

  • UV Protection Systems: Effective blocking of harmful UV-A and UV-B radiation
  • Raman Spectroscopy: Essential for laser line cleanup and Rayleigh scattering rejection
  • SO₂ Detection: Critical component for sulfur dioxide monitoring systems
  • Fluorescence Microscopy: Ideal for UV-excited fluorophore applications
  • Solar Simulation: Precise spectral control for photovoltaic testing
  • Photochemistry: Controlled UV exposure for research applications

Technical Advantages:

  • Sharp transition at 360nm for precise UV cutoff
  • High transmission (>90%) preserves signal integrity
  • OD3 blocking effectively suppresses harmful UV radiation
  • Extended transmission range covers complete visible spectrum
  • UV-resistant coatings ensure long-term stability

Specialized Applications:

  • Environmental Monitoring: Key component in SO₂ detection systems for air quality monitoring
  • Raman Systems: Essential for eliminating laser scatter and improving signal-to-noise ratio
