Tunable optical filters, such as bandpass filters, allow adjustment of the pass band's center wavelength. They can be manually adjusted, motorized, or electronically controlled, providing flexibility and precision in optical filtering applications.

Interactive Purchase Decision Tool

Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:

Go through the process:

1. Understand the technical background

It is important to sufficiently understand the technology before buying.

Use the comprehensive learning resources of RP Photonics:

If you need personal help, contact RP Photonics to get technical consultancy.

2. Define your requirements

It is essential to fully understand and clearly define your requirements before you purchase.

We recommend that you develop a list of clear specifications according to your specific needs, against which you can later check the suitability of found product offers:

To help you, we have already listed some aspects we recommend you consider when buying tunable optical filters. Of course, there may be other aspects that are relevant to your specific case.

This list is for your own preparation, and can later (possibly in modified form) be used for quotation requests to suppliers.

Otherwise, you will need to talk to your technical colleagues.

If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.

You find these buttons in the supplier list below or under "3. Find suitable suppliers".

3. Find suitable suppliers

We suggest three steps:

  • Below, you can find our list of suppliers for tunable optical filters. Use the checkboxes to mark possibly suitable suppliers.
  • The selected suppliers will appear below this list, along with your list of specifications. You can then indicate which specifications they meet according to your research. (You should finalize your specifications before doing this.)
  • Based on the results, you can finally choose a supplier that is hopefully a good enough fit.

4. Document the decision process

It is essential to document your purchasing process, not only its result (chosen supplier):

  • You will find it easier next time.
  • If something goes wrong, you can defend your decision by showing that you properly considered all important aspects. Or you see what needs to be done better next time.

tunable optical filters

The tunable bandpass filter offered by Spectra Quest Lab is an ideal filter with low loss (<3 dB), wide bandwidth (100 nm), and narrow linewidth (min. 0.03 nm) due to its unique optical structure. Input and output are via PM fibers. Wavelength tuning is done manually (adjustment by micrometer head) or automatically (adjustment by stepping motor). Different wavelength ranges are available: 870–960, 920–1020, 980–1080, and 1010–1110 nm.

tunable optical filters

Thorlabs’ digital tunable Gaussian bandpass filter is designed to operate with telecommunication C-band (1527 – 1567 nm) signals. It features a low insertion loss and a narrow passband of ≤0.77 nm at −20 dB. Our tunable bandpass Fabry-Perot filters enable filtering of low-light emission spectra over a narrow wavelength range of approximately 0.1 nm. Options are available for visible or near-IR operating wavelengths. We also offer Kurios liquid crystal tunable bandpass filters, which provide a fixed, continuously tunable center wavelength in the visible or near-IR range. A selectable bandwidth option is also available for visible wavelengths. When used with a light emitting diode and scientific camera, these filters are ideal for multispectral or hyperspectral imaging.
