Hi, I’m student of Electronic Engineering at the PUCP(http://www.pucp.edu.pe) and I’m working in a project to get my degree. It’s like a lowcost ROV to help researches of fishering gears in the peruvian context, the project is for the IMARPE(http://www.imarpe.gob.pe) the National Institute of the Peruvian Sea. I’m looking for the housing of the device, mostly I’m in the search of a transparent material in order to allow the camera to film. At first I thought in a bubble or just a circular glass.

I would like to get an estimate of the cost of the followings solutions for material wich its going to work about 100m-200m of deepnes:
A bubble: semi-esphere of 15cm of diameter
A circular shape also about 15cm of diameter
An entire cilindric chasis 15cm of diameter 30 cm height/ 20cm of height


I hope you can help me,

Best regards,
