Samsung ISOCELL’s All Lenses on Prism (ALoP) is a new and better periscope design | Infinium-tech

Samsung’s imaging team has come up with a new design for a folded telephoto camera module that will allow for a brighter lens (f/2.58 at 80mm) and a thinner overall footprint.

Called ALOP (all lenses on prism), it essentially moves the lens array to the top of the periscope prism rather than between the prism and the imaging sensor, as it is in a traditional folded design.

This is because in a typical folded telephoto module design, increasing the diameter of the lens pupil (making it wider and brighter) will increase the height of the module. With ALOP technology, you can get wider lens diameters without making the entire module larger.

So with ALOP, periscope cameras can have brighter lenses, leading to better performance in low light.

Samsung’s ICOCELL team says the design is 22% smaller than a traditional periscope and uses a 40˚-tilted prism reflection surface and a 10˚-tilted sensor assembly.

You can see the drastic reduction in module length and reduction in module thickness in the images below.

The display thickness may not look very big in the images, but it allows for a smaller camera bump, which is a priority for many buyers.

Samsung isn’t saying when we’ll see this new technology implemented, but a reasonable guess is on the Galaxy S25 series.
