19 Nov 2009 Eliminate any laser line within a wide spectral range with our TTNF. Selectivity resembles that of a triple spectrograph, but with higher throughput, much more compact, and a fraction of the price. Photon etc’s Tunable Top Notch Filter is optimized for Resonant Raman Spectroscopy using Ti:Saph laser. It can be customized to any specific wavelength range, typically 300 nm wide, from 633 nm to 1.7 µm. The Tunable Top Notch Filter is by far the narrowest notch filter in the industry (< 0.4 nm @ 633 nm), ideal for high efficiency simultaneous collection of low wavenumber Stokes and anti-Stokes signals. The Tunable Top Notch Filter has a high throughput (up to 80%), with a selectivity similar to that of a triple spectrograph, but at a fraction of the price. Also, our Tunable Top Notch Filter is a compact, easy to align instrument with an intuitive user interface that allows efficient and precise control. |
