OTF-950
Wavelength & Bandwidth Tunable Filter
Features
Next generation bundle wavelength OXC
Flexible test and measurement
Applications
The OTF-950 is a versatile bench-top optical tunable
filter that allows both wavelength tuning and passband
width selection simultaneously and independently.
Unique precision free-space optics and an accurate
tuning mechanism deliver excellent optical control and a
flat-top passband shape. Notch Type filter is also
available (custom-order).
