Hi,
I am trying to use my phone flash to trigger an underwater strobe and looking for your help. The flash easily activates the strobe when the fiber optic cable is placed in front of the flash outside the housing but the flash being so close to the lenses results in light being reflected back towards the camera resulting in hazy parts of the image.
I am looking to have the light be emitted near the hole below the flash as shown in the picture attached or in the following reddit post (Reddit - Dive into anything)
I have tried using a fiber optic cable placed 90 degrees to the LED with hot glue on each end but the light loss is too great and the strobe won’t trigger reliably.
I am looking towards using a light pipe to direct the light away from the lenses, probably a right angle low profile pipe as there is only about 3.5mm of clearance between the lens and the interior of the housing. Any ideas on how to achieve this? If a right angle light pipe exists that has a low enough profile, I could attache a fiber optic cable to it and then use a clear epoxy to diffuse the light towards the front of the housing.
I will attach the fiber optic cable from the strobe to the front of the housing with a mask and velcro so the external connection is not an issue.
Any ideas or recommended part numbers that may be useful in achieving this will be much appreciated.
Thanks in advance,
David
