Making Good Purchase Decisions

As the most professional photonics purchasing portal, RP Photonics helps you to not only to find all relevant suppliers (not limited to our advertisers), but also to make good purchasing decisions.

NEW: Structured Decision Process

Purchasing involves a lot of responsibility. We recommend that you apply best practice by using the following structured process: Go through the following expandable sections, complete the form and finally come to a purchase decision. You can then print that to a PDF for documenting the process.

Our article on best practices for purchasing and another one explaining this tool give you valuable insights.

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 buy.

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 nonlinear frequency conversion equipment. 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 nonlinear frequency conversion equipment. 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.

nonlinear frequency conversion equipment

NLIR's SPEKTRUM Wavelength Converter efficiently converts wavelengths from 1.9 – 5.3 µm in the mid-infrared to 682 – 886 nm in the visible/near-infrared (VIS/NIR). This conversion is simultaneous and does not require time lag or scanning elements. The output is compatible with standard fiber-coupled grating spectrometers or silicon-based sensors.

NLIR's TUNE Wavelength Converter is optimized for high conversion efficiency within a narrow bandwidth, ideal for sensitive mid-infrared light measurements. It operates over a tunable range from 2.7 – 4.3 µm, with the converted light shifted to 763 – 853 nm, suitable for any fiber-coupled detector operating in these near-infrared wavelengths.

The TUNE Wavelength Converter is particularly effective for detecting narrowband signals, whether weak or rapidly varying. It supports measurements with time-gated PMT, SPAD detectors, APDs, and high-speed PIN photodiodes.

Now you can read mid-infrared data with your VIS/NIR spectrometer/detector.
