Bandpass Filters for Spectroscopic Applications

Lightwaves2020 specializes in manufacturing a wide wavelength range and high OD blocking thin film filters for spectroscopic applications.Features

• Wide operating wavelength range:
• 200~1200nm for biomedical
• 400~1200nm for visible optical sensing
• 600~1700nm for NIR
• 400~3200nm for IR spectroscopy
• Typical bandwidth: FWHM 10nm to 40nm
• High OD blocking:
• >5OD for UV/Vis/NIR
• >3OD for IR 400~3200nm
• High transmittance: >70% (NIR), >60% (Vis), > 50% (UV)
• Steep slope: <10nm across 50% of Tpeak to 5OD in UV/Vis/NIR
• High laser damage threshold: >2J/cm2 (532nm)
• Low auto-fluorescence in UV/Vis for fluorescence microscopic imaging
• Superior environmental reliability

Applications

• Spectroscopic research
• Spectroscopes
