Fiber-Optic Modules

Wavelength Tunable Filter with Exchangeable Filter
→ TFM/FC
By exchanging the cassette, TFM can change its spectral characteristics including the tunable wavelenth range.
The center wavelength can be tuned until 20nm.
The micrometer enable the fine wavelength tuning.

Wavelength Tunable Filter with 2 Exchangeable Filters
→ WTFM/FC
Arbitrary spectrum characteristics can be formed by using 2 optical filters.
The center wavelength can be tuned until 20nm.
The micrometer enable the fine wavelength tuning.

Visible light Wavelength Tunable Filter with Exchangeable Filter
→ VTFM/FC
By exchanging the cassette, VTFM can change its spectral characteristics including the tunable wavelenth range. This type TFM can tuning visible ligth wavelength.
The center wavelength can be tuned until 10nm.
The micrometer enable the fine wavelength tuning.

Filter Cassette for Wavelength Tunable Filter
(TFM/WTFM/VTFM)

Automatic Wavelength Variable Filter
→ AWVF
It is easy to carry out the control in connection with a PC. AWVF can be used for wavelength variation of 100 nm or more.

3-port Transmission/Reflection Filter Module
→ TMUX
TMUX is a wavelength tunable ADD/DROP multiplexer/Demultiplexer that changes the wavlength of transmitting light and reflecting light simultaneously.
TMUX can tune the wavelength by 10nm at the maximum.
Thanks to the micrometer used for wavelength tuning mechanism, fine and precise tuning is achieved.

Compact Fixed Wavelength Optical Filter Module with 8mm Square in Cross Section
→ ILF

Compact Wavelength Tunable Filter Module with 8mm Squre in Cross Section
→ FBPF
The center wavelength can be tuned until 5nm.

Wavelenth/FWHM Tunable Filter
→ ITF-201A Series
Both wavelength and FWHM are tunable.
This product is using six optical filters at the maximum and forms various types of optical filters.
Wavelength/FWHM tunable type does not function as only BPF but also LPF/SPF by switching operation mode, and is applicable to various purposes.
