1. An optical assembly comprising,
a transparent optical element comprising at least first, second and third sides, wherein an angle between the first and second sides is less than 180 degrees, and wherein the third side is non-parallel with the first and second sides,
an optical reflection surface configured to deflect a light ray transmitted through the first side,
a transparent, deformable, non-fluid body comprising a first surface and an opposite second surface, wherein the optical reflection surface, the first surface of the non-fluid body and the first and second sides of the transparent optical element are connected via one or more interconnected optically transparent components, and wherein the refractive index throughout the connection is greater than the refractive index of air,
an actuator system comprising one or more actuators and an actuator-component configured to undergo bending and/or displacement by the one or more actuators, wherein a side of the actuator-component abuts the second surface of the non-fluid body, wherein
the one or more interconnected optically transparent components comprises the non-fluid body and the transparent optical element, wherein the non-fluid body has the same or substantially the same refractive index as the transparent optical element and/or the actuator component, and wherein
the third side of the transparent optical element comprises the optical reflection surface, alternatively,
the actuator-component comprises the optical reflection surface arranged as a reflection surface on the surface of the actuator-component facing the optical transparent element or arranged as a reflection surface on the opposite surface of the actuator-component wherein the first surface of the non-fluid body abuts the third side of the transparent optical element,
whereby
the optical reflection surface is configured to deflect the light ray transmitted through the first side towards the second side.
