Discover the Industrial Helios2 Time-of-Flight Camera
A Quick Look
The Helios2 3D Time-of-Flight (ToF) camera provides real-time 3D depth imaging with high accuracy and sub-millimeter precision. Featuring Sony’s IMX556PLR ToF sensor combined with LUCID’s Factory Tough IP67 design, this camera is perfect for 24/7 operation in challenging industrial environments.
The Helios2+ is an advanced version of the Helios2 ToF camera offering two additional modes: High Dynamic Range mode and High-Speed ToF mode. The High Dynamic Range mode fuses multiple exposures to provide accurate depth information in scenes containing both highly reflective and low reflective objects. The High-Speed mode enables depth perception using a single phase measurement to realize faster acquisition speed and higher framerates for moving targets at the expense of absolute accuracy and measuring distance range. Both HDR and High Speed modes are realized entirely with on-camera processing.
The Helios2 Wide quadruples the viewable area thanks to its wider 108° x 78° field of view (compared to the Helios2/2+ 69° x 51° FoV). This allows the Helios2 Wide to image a much larger area at the same distance of a Helios2 or image the same area but at a closer distance to the target, allowing for more flexibility with camera installation.
All Helios2 models share the same Factory Tough industrial design with IP67 dust and water protection and is 100% mechanically and software compatible with each other.

Helios Videos
The Helios2+ High Dynamic Range mode fuses multiple exposures in the phase domain to provide accurate depth information in high contrast, complex scenes, containing both highly reflective and low reflectivity objects.
The Helios2+ High-Speed mode enables depth perception using a single phase measurement to realize faster acquisition speed and higher framerates. This allows 3D imaging of moving objects without distortion at the expense of accuracy and distance range.
The Helios2+ High Dynamic Range mode fuses multiple exposures in the phase domain to provide accurate depth information in high contrast, complex scenes, containing both highly reflective and low reflectivity objects.
The Helios2 combines a factory tough design with exceptional 3D precision and accuracy into a compact IP67 machine vision camera. Featuring Sony’s IMX556PLR DepthSense sensor, learn what’s new in the Helios2 and how it compares to the original Helios in this video.

Factory Tough Design, 24/7 Industrial Operation
The Helios2 ToF camera is engineered for high performance operation in industrial environments. Built for demanding 24/7 environments and a variety of industrial 3D applications such as robotics, 3D inspection, and logistics, including advanced material handling, pick and place, sorting, palletization / de-palletization, volume estimation, and more.
Raising the Bar for Superior Time of Flight
The Helios2 architecture is engineered for the next generation of high-performance 3D ToF imaging, delivering sub-millimeter precision and improved accuracy compared to the previous Helios. The calibration between the VCSELs and sensor timing is enhanced resulting in more 3D detail, along with improved attention to edge detection to reduce flying pixels and overall noise. 3D calculations are done on-camera, reducing CPU load and freeing up host PC resources.
Fast Processing Directly on the Camera
By processing the data directly in the Helios2, you reduce the need for expensive host system components. The 3D coordinates, intensity and confidence data, are delivered directly from the camera. The point cloud data is generated in real time.
Easy 3D Controls
The Arena SDK includes easy to use controls for the Helios2 ToF camera. ArenaView allows for 2D and 3D views: 2D view allows one to see the intensity and depth of the scene from the camera’s perspective. 3D view displays a point cloud of the scene and allows users to manipulate the orientation in real-time. Additionally, settings can be changed in real-time such as false color overlay, depth range adjustments, out of range color settings and more.
