Band Pass Filters for Spectroscopic Applications

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) - Visible Spectroscopy (400 ~ 900nm)
– Center Wavelength: customer specific
– Typical FWHM: 10 ~ 15nm - 200 ~ 1200nm
– Center Wavelength: customer specific
– FWHM: typical 10nm - NIR Spectroscopy (700nm ~ 1700nm)
- 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
