Optical Tunable Filter with wavelength indicator OTF-320 (:437KB)

Manually tunable wavelength optical filter

The OTF-320 is a manually
tunable wavelength optical filter that uses the linear sliding method. This product has a wide variety of filter profile options with combining filter type and number of cascaded filters (S1, S2, and S3) to suit most fiber optic applications. It is suitable for basic laboratory use and also for system integration of wavelength selection during installation.
