Ultra-Narrow Bandwidth-Variable Tunable Filter
Optics & Photonics | Test & Measurement | Optical Signal Conditioning
An essential tool for wavelength-selective filtering of optical signals in research and development as well as in the laboratory environment.
Ultra-Sharp Edge Roll-Off
The filter exhibits an ultra-sharp roll-off of 1500dB/nm (12dB/GHz), without compromising the flexibility of bandwidth and wavelength tuning. Ideal for DWDM channel selection and removing ASE noise.
Continuously-Tunable Bandwidth: 0.03 to 3nm
The 3dB bandwidth is 30pm (3.7GHz) at its narrowest and is also continuously tunable to 3nm (370GHz). Filtering of<1GHz optical frequency comb lines is also possible by combining with etalons.
