Scope of 360° view lenses: Multi-view applications

Another scope of 360° view lenses is to obtain a multi-view image for many demanding applications. Pericentric and Catadioptric lenses are great choices when 360° inspection is needed without multi-camera systems. For applications focused on samples that do not feature axial symmetry, Opto Engineering multi-view lenses can provide a user with a full 360-degree view through optical mirrors. By introducing mirrors and prisms on the optical path, the Field of View is divided into multiple views of the product.

The PCMP and TCCAGE lens series integrate telecentric optics, leveraging the low distortion and lack of perspective error of telecentrics to capture high-precision images that can be used for both measurement and inspection applications.

The TCCAGE is an integrated optomechanical system designed to fully inspect and measure parts from the side without any need of rotation. Four 90-degree views of an object are provided by a bi-telecentric lens through an array of mirrors. Two different illumination devices are built into the system to provide either backlight or direct part illumination.

The PCMP series features multi-image lenses designed to completely measure and inspect objects by generating six different lateral views provided by an array of mirrors interfaced to a bi-telecentric lens. The lens integrates diffused LED illumination optimized for this specific assembly.

PCPW optics provide eight different views of the side and top surfaces of an object. The wide angle of view (45°) enables the inspection of the side features of an object that otherwise would be impossible to acquire with a single camera. Both an object's external walls and its top can be imaged at the same time, while internal surfaces of hollow objects can be fully inspected from the outside.

Typical application examples are 3D inspection of an electronics part on a PCB board, Data matrix reading on a pharmaceutical vial or alignment checking on syringe needles.
