Purchasing advisor for beam expanders with supplier directory and AI-based advice; telescope, variable ratio, beam radius, long-distance transmission (original) (raw)
Find all you need for professional sourcing of beam expanders: 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.
NEW: Not only hardware can be listed here, but also consulting, software, training on beam expanders, etc. – see the "offer types" below.
🌐 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.
Purchasing high-value photonics products is a substantial responsibility. Using a structured decision-making process and high quality supplier data helps a lot:
- Find all relevant suppliers (not limited to advertisers).
- Our interactive tool conveniently assists you in defining and applying your application-specific requirements.
Note that purchasing decisions based on just a few randomly picked suppliers and without carefully defined specifications are risky; therefore, we strongly recommend using our data and tool. See also:
- How Responsible Purchase Decisions for Expensive Goods Like Lasers Are Done
- Explanations on this purchasing tool
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.
I feel that I sufficiently understand the technical background.
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 beam expanders. 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.
I think that I am sufficiently informed about our requirements.
Otherwise, you will need to talk to your technical colleagues.
I consider the above list of specifications to be sufficiently complete, clear and accurate.
If you cannot sufficiently clarify your requirements, you may want to get technical consultancy from RP Photonics.
Insert these criteria when creating inquiry mails to suppliers with the buttons "Get quotation".
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 beam expanders. 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.
Selected suppliers:

The most suitable supplier you found:
Comments, e.g. reasons for your choice, or things which still need to be checked:
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.

 Your Custom Optics Expert Shanghai Optics Inc.425 Main St Suite 2EMetuchen, NJ 08840United States |
⚙ hardware Shanghai Optics Inc's custom beam expanders are used in many applications such as laser ranging, laser illumination, interferometry, etc. In high-power laser systems, beam expanders are used increase the beam area without significantly affecting the total laser energy. This results in a reduction of the laser power density which reduce the risk of damaging the coatings and optical materials of optical components. In a laser ranging system, a beam expander is used to minimize the laser divergence, resulting in a smaller collimated beam at a long distance. Product-specific web page |

 DPM PhotonicsP. O. Box 3002Vernon, CT 06066United States |
⚙ hardware Photonic Devices' precision Galilean beam expanders have been sold globally for over 20 years and include an extensive number of standard models. These multi-element beam expanders have been computer-designed to provide excellent wavefront quality with minimum beam deformation. All lens elements are air spaced and the majority of models have variable air spacing for collimation adjustment. All lens surfaces have multilayer antireflection coatings, with power handling capabilities over 1 kW (> 200 W for beam expanders operating at 10.6 microns). Product-specific web page |
