Product Family Description

  • Center Wavelengths from 365 to 1550nm
  • 10, 25, or 50nm Full-Width Half Maximum Options
  • High Transmission and Deep Blocking
  • Mounted OD 4.0 5nm, 10nm, 25nm and 50nm Bandpass Filters Also Available

TECHSPEC® Unmounted OD 4.0 Bandpass Filters are available with a 10, 25, or 50nm full-width half maximum (FWHM). The narrowband 10nm bandpass filters are ideal for laser line separation, flame photometry, or chemical detection applications. The broadband 25 and 50nm filters are used in a variety of life science and machine vision applications, including preventing photobleaching of fluorophores and improving the signal to noise ratio of imaging systems. TECHSPEC Unmounted OD 4.0 Bandpass Filters are designed with center wavelengths from 365 to 1550nm, covering common laser lines and spectral lines, and provide OD 4.0 blocking outside of their passband. Standard diameter sizes of 12.5 and 25mm facilitate integration into benchtop optical systems or life science instrumentation.
