Purchasing Advisor for Position-sensitive Detectors

Find all you need for professionally buying position-sensitive detectors: an interactive tool with a comprehensive and trustworthy directory of suppliers and expert guidance for a structured decision process with scientific and technical background information.

Top-level product category: icon detectors and measurements

More general product categories: photodetectors

Position-sensitive detectors measure the position of light spots in one or two dimensions. These can be segmented photodiodes, photodiode arrays, or analog devices based on other principles, providing accurate position sensing.

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 position-sensitive detectors. 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 position-sensitive detectors. 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.

Our interactive tool makes it easy: Fill out the form, and in the end print it to a PDF. Note that the document will show all sections (including those not currently shown on the screen), while omitting some irrelevant details such as the page navigation.

position-sensitive detectors

Hamamatsu Photonics PSDs are optoelectronic position sensors that utilize photodiode surface resistance. Unlike discrete element detectors such as CCDs, PSDs provide continuous position data, high position resolution, and high-speed response.

position-sensitive detectors

Gentec Electro-Optics offers measurement systems for laser beam pointing based on large area pyroelectric quadrant detectors. The instruments respond to laser beams from the UV to the far IR and can be used even in the terahertz region. Versions for pulsed sources, CW and high repetition rate (quasi-CW) operation are available.
