Purchasing Advisor for Infrared Detectors

Find all you need for professionally buying infrared detectors: a comprehensive expert-curated directory of suppliers, scientific and technical background information, and an interactive AI-based tool with guidance for a structured decision process.

You appear to be visiting from North America. Many listed suppliers are based in this region, making the RP Photonics Buyer's Guide highly relevant for your needs.

Top-level product category: icon detectors and measurements

More general product categories: photodetectors

Various types of photodetectors can be used for infrared radiation. They are often based on semiconductors with small bandgap energy, and those for relatively long wavelengths often need cryogenic operation conditions. These detectors are crucial for applications in astronomy, defense, and industrial process monitoring.

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 infrared 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 infrared 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.

Sophisticated Tools for Signal Recovery

FEMTO Messtechnik GmbH
Klosterstraße 64
10179 Berlin
Germany

infrared detectors

FEMTO offers a wide range of very low-noise infrared photodetectors. They offer bandwidths up to 2 GHz and gains up to approximately 1011 V/W, resulting in measurement ranges from sub-pW to mW. The NEP reaches a minimum of 7.5 fW/√Hz using InGaAs photodiodes covering a wavelength range up to 1700 nm, with either a free space or fiber input (FC/PC, FC/APC). Many types and models are switchable in gain and bandwidth and can be controlled manually or remotely via PC. Customized models are available upon request.

ALPHALAS GmbH
Bertha-von-Suttner-Str. 5
37085 Göttingen
Germany
Profile page  Website  
infrared detectors

Ultrafast photodetectors from ALPHALAS are suitable for measuring optical waveforms with rise times starting from 10 ps and spectral coverage for the IR region up to 2600 nm have bandwidths from DC up to 30 GHz. Available configurations include free-space, fiber receptacle or SM-fiber-pigtailed options and have compact metal housings for noise immunity. For maximum flexibility, most models are not internally terminated. A 50 Ohm external termination supports the highest speed operation, while a high impedance load generates large amplitude signals.

Applications include pulse form and pulse width measurement, laser synchronization, mode beating monitoring and heterodyne measurements. Balanced photodiodes complement the large selection for these models.
