Band Pass Filters for Spectroscopic Applications

Band Pass Filters for Spectroscopic Applications Image

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

General 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:
    – >5 OD for UV/Vis/NIR
    – >3 OD for IR 400 ~ 3200nm
  • High transmittance: > 70% (NIR), > 60% (Vis), > 50% (UV)
  • Steep slope: < 10nm across 50% of Tpeak to 5 OD in UV/Vis/NIR
  • High laser damage threshold: > 2J/cm2 (532nm)
  • Low auto-fluorescence in UV/Vis for fluorescence microscopic imaging
  • Superior environmental reliability

Sample Curves

  • Biomedical Spectroscopy: 200 ~ 1200nm
    – Center Wavelength: customer specific, within 300nm to 1000nm
    – FWHM: 40nm (or customer specific)

    BPF550

  • Visible Spectroscopy (400 ~ 900nm)
    – Center Wavelength: customer specific
    – Typical FWHM: 10 ~ 15nm

    BPF552

  • 200 ~ 1200nm
    – Center Wavelength: customer specific
    – FWHM: typical 10nm

    BPF800

  • NIR Spectroscopy (700nm ~ 1700nm)

    BPF1100

  • IR Spectroscopy
    – FWHM: typical 15nm
    – Peak Tran. > 75%
    – Blocking: 400 ~ 3200nm, > 2.5 OD
    – Channels: 1680, 1722, 1759, 1818, 1940, 2050, 2100, 2139, 2180, 2230, 2310, and 2345nm
