What is a diffraction gratingin physics

Featuring a Sony DepthSense™ IMX556PLR 1/2" global shutter CMOS sensor, the Helios 3D time of flight (ToF) cameras output 3D point clouds in real-time for use in a variety of industrial 3D sensing and depth measurement applications to sub-mm (< 1mm) precision with optional 3.2MP color image texture-mapped overlay.

A diffraction grating can be a reflection grating or a transmission grating. The most common type of diffraction grating are plane gratings and concave gratings although they can also be other profiles such as convex or toroidal depending on the application.

Lucid Vision Labs Helios 3D Time of Flight (ToF) cameras are built to stand up to harsh industrial environments with IP67 protection and resistance to shock & vibration without heatsinks or fans. These ToF GigE cameras adhere to GigE Vision and GenICam 3D standards, and with the M12 connectors the cameras are easy to install. In addition, they are 100% mechanically and software compatible with each other.

Typically, the cost of producing a master diffraction grating is expensive and by supplying replica gratings (which offer almost indistinguishable performance), one master may produce thousands of replicas, lowering the unit cost of the diffraction grating.

A ruled diffraction grating is produced by a ruling engine that cuts grooves into the coating on the grating substrate (typically glass coated with a thin reflective layer) using a diamond tipped tool.

A holographic diffraction grating is produced using interference lithography which results in a smooth groove surface and eliminates the periodic errors found in ruled gratings.

What is gratingelement

The groove density, depth and profile of a diffraction grating dictate the spectral range, efficiency, resolution and performance of the diffraction grating.

What is a diffraction gratingused for

A diffraction grating can have a sinusoidal or blazed profile. A sinusoidal grating generally offers lower efficiency than a blazed grating, but often gives a broader spectral coverage. A blazed grating has a ‘saw tooth’ profile and normally offers higher efficiency.

Lucid Vision Labs Helios2 3D Time of Flight (ToF) cameras, Helios2+ 3D Time of Flight (ToF) cameras, Helios2 Wide 3D Time of Flight (ToF) cameras, and Helios2 Ray Outdoor Time of Flight (ToF) 3D Cameras combine a Lucid Vision’s rugged IP67 Factory Tough™ design with exceptional precision and accuracy into a compact 3D machine vision camera that is ideal for industrial 3D and ToF applications such as robotics, 3D inspection, and logistics.

What is gratingin physics

Reflection gratings are normally coated with a reflective coating, usually aluminum with a protective overcoat for UV-VIS-NIR use or gold for IR use. Transmission gratings are usually supplied with an antireflection coating.

Multiple operational working distance modes maximize 3D performance based on the required distance range and come with the ability to adjust the starting point of each model along the entire working range of the camera. The included Arena SDK and 3D point cloud viewer software enables quick and easy integration into a wide range of 3D imaging applications.

A commercial diffraction grating is generally a replica grating produced from a sub-master, which may be a number of generations down from the master diffraction grating.
