LASER LINE TUNABLE FILTER
The Laser Line Tunable Filter is a non-dispersive, sub-nm tunable bandpass filter that transmits a single laser line while blocking unwanted lines and fluorescence. It delivers the highest signal throughput in the industry. Output pointing is very stable while changing wavelength, removing the need to realign optical setup. This filter is perfectly matched to our Tunable Top Notch Filter for Raman applications. It is also ideal as a pre-monochromator for triple spectrograph systems using various wavelengths. The Laser Line Tunable Filter is compatible with any visible and NIR broadband source. Free space of fibered. The Laser Line Tunable Filter is the only tunable filter exhibiting an isolation higher than OD4.
