ADAS LiDAR heaters

LiDAR sensors are a key technology in Advanced Driver Assistance Systems (ADAS). Together with cameras and radars, LiDARs enable understanding the environment in real time. LiDAR heaters based on the unique Canatu CNT technology ensure reliable LiDAR performance in any weather.

The most advanced transparent heater for LiDAR

Reliable LiDAR systems are critical in the development of autonomous driving. Key challenge in the automotive LiDAR adoption is to secure clear visibility in inclement weather. Accumulation of snow and ice can cause perception challenges preventing accurate 3D mapping of the vehicle’s surroundings.

Canatu film heaters provide efficient deicing and defogging of the LiDAR lens advancing autonomous driving in any weather. Canatu LiDAR heater features excellent transmission, high heating performance, and excellent processing ability, making it ready for scale up.

Key benefits:

  • High transmittance at near infrared wavelengths
  • Wire-free at LiDAR field-of-view without optical distortion or laser beam deflection
  • Fast, even and power-efficient heating
  • Can be implemented on a variety of flexible film substrates including PC and PET
  • 3D formable and moldable
  • Proven automotive-grade reliability

Record high transmittance and conductivity

Canatu LiDAR heaters can be flexibly tailored to meet customer heating, optical, and design requirements across a range of input voltages. Our heaters exhibit very high transmittance for near infrared wavelengths, and are typically fabricated at sheet resistance values of 70 – 200 ops, equaling 96-99% T at 905, and 97 – 99% T at 1550 nm (without substrate).

  • 51Ω/sq at 95%T at 905 nm
  • 130Ω/sq at 98%T at 905 nm
  • 39Ω/sq at 95%T at 1550 nm
  • 93Ω/sq at 98%T at 1550 nm




Even and power-efficient heating

Canatu LiDAR heaters provide fast, even and power-efficient heating across the whole surface without optical distortion and temperature gradient. Heating wires can cause signal-deteriorating temperature gradient distorting the field-of-view. Canatu film heaters are transparent at field-of-view offering industry-leading optical performance for LiDAR applications and beyond. All Canatu film heaters can be equipped with an optional real-time temperature monitoring for optimized power consumption.



Design and integration flexibility

Canatu film heaters can be implemented on a variety of flexible film substrates including PET and PC, and the stacks can be optimized for either in-glass, on-glass or film-insert molding integration. Advancements in integration have led to improved wavefront uniformity.  Today, Canatu has a focused portfolio of verified solutions for different substrates and integration methods.

Taking ADAS LiDAR heater performance to new levels

The high-precision laser technology used in ADAS LiDAR solutions raises the requirements for automotive heaters to a completely new level. Extremely high optical requirements combined with the need for even and efficient heating as well as seamless design integration render most traditional heating solutions unsuitable.

In contrast, Canatu ADAS LiDAR heaters are able to meet this tall order with their outstanding optical and mechanical properties. In addition, their high flexibility allows them to be molded into any 3D shape, enabling easy integration and extensive design possibilities.

Furthermore, with Canatu having been in mass production in the automotive industry since 2015, the company has both the expertise and capacity to take on demanding projects in this field.

Industrializing Canatu CNT with DENSO

In 2021, Canatu signed a major Joint Development Agreement with leading mobility supplier, DENSO, to develop high-performance reactors used in CNT film production. This collaboration is aimed at effectively tripling Canatu’s current film manufacturing productivity, which in turn enables DENSO to strengthen its capabilities in ADAS LiDAR heaters and camera heaters. The agreement signifies a key milestone in parties’ long-standing business partnership.
