 Dear Olga,
Thank you for all your assistance. we are very interested for Inline or H model, but  in our university we could not produce waterproofing case, because of this we prefer  to you build it, of course if is it possible. 
The waterproof case is separate from camera or they are interconnected?and how can we order the camera?
I looking forward hearing from you.Best RegardsElham

 Dear Elham,
The waterproof case for the camera NC353-369-STEREO was designed by one of our clients - an company in Australia, Mercurien. We were offering it on our site, but it has to be purchased separately, from them.
Nc353-369-Stereo camera is our older model, which can be sold at it regular price, and I can send you a quote. 
We are interested in sponsoring new camera models to have more Free Software developed for the new models. 
We would still recommend the H-camera - Andrey had explained it's benefits for your application, and we can offer it at 50% off (which is the cost of manufacturing). We also are working on the waterproof case for H-camera.

Please let me know how would you like to proceed.
Best Regards,

Hello Olga,Thank you for best reply and good explanation.  As I said before, this robot boat is planned to reach a mass production for the near future although our country, Iran. Also, we have website (http://emorvarid.ut.ac.ir/) and we put scientific articles on that and after finishing of design and test, we report results of this robot on this website. In fact, we still have not tried Github or similar until now. We will be very happy if you contribute in this project.As I said earlier waterproofing is very important for ours, so we want to order NC353L-369-STEREO with water proofing enclosure PTP100044. Can we order to change baseline of this camera? Is it possible to sponsor these?  we are eagerly awaiting your response

 Hello Elham,
thank you for your reply.

I would like to clarify that we at Elphel do not make custom designs, we offer our customers freedom to modify our cameras in software and hardware, including customization of the camera body. You are welcome to waterproof any of our camera models, as long as your new design is distributed under GNU GPL and CERN OHL licenses. We provide all the information about camera components on our wiki under these licenses and according to the licenses modifications can be made by third party to all our designs as long as they are distributed under the same license and are available to download, so others can use your designs as well.
Also I have to remind you that Andrey was saying in the beginning of your conversation: We at Elphel are interested in sponsoring a Free Software and Open Hardware project, made by the students as part of their research, which will be available at all stages of it's development, for which you need to start project on the repository such as GitHub, or similar, and all software and documentation related to camera use and integration with other devices such as your boat needs to be available.
We will not sponsor a proprietary project, as it is against our company philosophy and we also do not gain any value to our products by doing this.

Answering your questions: 
4.5mm lens will work well for 20 meters and for 100 meters, so there is no need to change the lens. We can only design the waterproof camera for the H-camera with these 4.5mm lenses, as one of our standard cameras. Designing waterproof case for inline camera with different lenses - is custom design and development cost is very high - $100,000 as a minimum.  Again - you are welcome to design and build it yourself using 3D models of our camera parts, and purchasing only camera electronic boards, as NC393-DEV, offered here: http://www3.elphel.com/ importwiki?title=Price_list

About the lenses: if you would like to use Inline camera with different lenses, then the outer lenses focal length should be directly proportional to the distance between these 2 lenses.  In other words the proportion should be  approximatelly like this: 4.5mm / 22cm =  X mm / 36cm, where 4.5mm - is the focal length of the inner lenses, 22 sm is the base between inner lenses and X - is the focal length of the outer lenses with the base between outer lenses 36cm (for example) .

But again, you can use 4.5mm lens for up to 100 meter distance, as we use these lenses in our Eyesis4Pi cameras: http://www3.elphel.com/model_ 353_cameras
you can see the image samples made with these lenses by this camera: http://www3.elphel.com/ eyesis4pi_samples 

As I said earlier - designing waterproof case takes a lot of our time and resources, and it can not be done too quickly. I think we might have some prototype ready in about a month, but maybe your team can do it faster. You are welcome to share your waterproof design and we can provide consultation to you regarding your design.

We can ship camera to address in Georgia, shipping time would be about 2-5 business days usually, depending on the shipping service. H-camera or Inline camera without waterproofing is ready and can be shipped within a few days after payment is received.

Best Regards,

Olga

Hello Olga,I apologize for delay. I must consult with my supervisor. According to our calculations, baseline 22 cm and focal lens 4.5 mm is suitable for inner cameras and for outer cameras we need larger focal length and we don't know exactly what kinds of lenses do you have for this purpose? because we want to use inner cameras in 4-20 meters, and outer camera in 20-100 meters(on your opinion what kind of lenses is suitable for 20-100 meters?).
 My supervisor emphasis on waterproofing, he said that H-model or Inline model that is waterproofing is appropriate for ours. Now, on your opinion, when is H-model waterproof enclosure ready?my friend lives in Georgia, can you send camera for her? how long does it take to get to her?

I looking forward hearing from you.
Best Regards Elham

 Hello Elham,
all camera models made with 3D-printed parts are just examples of the possible configurations. We offer our clients the freedom to modify camera configuration based on their needs and application. The camera with 4 sensors can be arranged in any way you  want to design it. It is also possible to purchase the example Inline camera. It has a fixed baseline of 250mm, but it can be larger, limited only by the cable length. The longest cable we offer is 450 mm, so the largest baseline could be something like 700mm.
Please note that we are working on the waterproof camera body for the H-camera, not the Inline camera.

The 4 image sensors are synchronized and are taking images simultaneously.

The lens we offer is Evetar, N125B04530WR1 with EFL=4.5mm, the focus is fixed on infinity. http://www3.elphel.com/ accessories
You can also choose your own lens (C or CS mount, or M12 mount).

Best Regards,

Hello Olga,Thank you for your guidance.I have a few questions: In this Model (Inline model) is the baseline  variable?
In this system, are two cameras (or all of them) used at the same time?
Does the lens have focus?
Kind Regards
Elham

 Hello Elham,
yes it will be possible to order the Inline model stereo camera with 4 sensors. 
As Andrey have mentioned, Elphel cameras are Free Software and Open Hardware and are distributed under GNU GPL license http://www.gnu.org/licenses/ gpl.html and CERN OHL http://www.ohwr.org/projects/ cernohl

 We would like to sponsor your project and follow it on Github repository (for example), or Sourceforge or Bitbucket with sources available for download. Here is an example of another project which had used Elphel cameras for their robots: https://bitbucket.org/ scinirov/scini/src/ 66a3b41e2763737dfa6ae5aab79a38 b86674d702/build/source/?at= master

 We have started designing the waterproof camera body, and some parts can be 3D-printed, however some parts we will order to be machined. Finishing the design, manufacturing parts, assembling and testing will take some time. Maybe you can make waterproof case faster. We will upload the parts for waterproof body as Open Hardware once it is ready, and you are welcome to share your design as well.

Please let me know how would you like to proceed with the order, and if you will have any other questions.

Best Regards,

Olga

Hello Andrey,Thank  you for your detailed explanation. Ok, we can design waterproof enclosure for camera. Is it possible for me to order Stereo camera with 4 sensors Inline Model instead of H Model? because it is very suitable for ours.Kind Regards

 Hello Elham,

As I wrote you earlier - we do not have any waterproof camera, the only weatherproof (they withstand rain but can not go underwater) we manufacture is Eyesis4pi (it is more expensive device).

Our users were able to use Elphel cameras deep under water (see project SCINI -https://www.google.com/ search?q=scini ), but it is their design, not ours. We provide open hardware cameras so you can download all our design files and develop the additions required for your particular application, and if your design is open too (so others can use your CAD files, software under acceptable FLOSS license) we may provide discounts (as I wrote earlier).

We may develop some weather-proof H-camera ourselves, especially if there will be customers eager to pay for such product. But I can not promise to put all our work aside do develop such new hardware - we can do it only in our spare time (which currently we do not have). Your team has at least twice more members than we have at Elphel, so you can develop mechanical parts yourself (as other users do) faster (and less expensive too) - we can definitely help you with consultations and tell if we think your design will work, what potential problems it may have.

Andrey

Hello Andrey,The longest of your cable is very good.because this camera will be used in outdoor condition, it is very important that it is waterproof.  can you design  H-camera with environmental protection?How will send us? and how many days does it take?
