1064nm SM Isolator & Band Pass Filter Hybrid Combination

The 1064nm SM Isolator & Band Pass Filter Hybrid Combination is a combination of a BPF and a low power isolator in a single compact package. All input and output fibers are polarization independent. It guides optical light in one direction and block out unwanted noise signals, eliminates back reflection and back scattering in the reverse direction. This product offers integrated solution to fiber laser and fiber amplifier application by combining more functions into a very compact package.

If you do not see a standard BPF & isolator that meet your needs, we welcome the opportunity to review your desired specification and quote a custom isolator. Requests for custom fiber pigtails, different wavelengths and handling power of operation or other specific needs will be readily addressed. DK Photonics can respond to custom requirements with short lead times.

Above specifications are for device without connector.
For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower.Power transmitsthrough the connector less than 2W.
Forthis 1064nm Isolator,Due to high IL, it is recommended to use average power of <200mW for single stage and <100mW for dual stage. If you need higher handle power, please look for our TGG based High power isolator&BPF.
If there is pulse application, please be sure to inform us of pulse energy and peak power.

Package Dimension

The default is without a reflective port.If the power to be blocked is relatively high, it is recommended to have a reflective port to guide the energy out of the shell.
Due to ongoing design improvements, the package size is subject to change.
