Benewake provides LiDAR-based assisted focusing solutions that enhance focusing speed and accuracy for cameras, projectors, and infrared thermal imagers through real-time precise distance measurement, suitable for intelligent driving, security monitoring, and non-contact temperature screening.
Camera Assisted Focusing
In low-light or complex scenes, the autofocus performance of cameras is often limited, resulting in blurry images. Installing a LiDAR sensor provides real-time, precise distance data to help the camera focus quickly and accurately, improving image clarity and shooting quality to ensure ideal results every time.
By installing the Benewake TF-NOVA LiDAR next to the camera lens, its linear laser beam covers a wide range of perception and distance measurement in front of the camera. When the user aims the camera at the subject, the TF-NOVA rapidly provides the precise distance to the object, helping the camera lens automatically adjust its focal length based on this distance for fast and accurate focusing.

Core Advantages
- Wide Measurement Angle: Unlike traditional LiDARs that use small dot light sources, the TF-NOVA uses a linear laser spot, covering a 14° measurement range. At a distance of 1 meter, the coverage width is approximately that of an adult, significantly reducing focusing errors caused by small spots missing the target object.
- Long Range: It offers a measurement capability of over 7 meters indoors and ensures effective measurement up to 3 meters even under bright noon sunlight, easily adapting to various camera shooting scenarios.
- Compact Size: Easy to integrate into various cameras and instant cameras without affecting aesthetics.

Assisted Focusing for Other Devices
With the rapid development of intelligent recognition, attendance, security, monitoring, and epidemic prevention in China, refined target identification has become an urgent need for projector, temperature measurement, and camera manufacturers.
Benewake has launched a LiDAR-assisted focusing solution to help camera, projector, and temperature measurement manufacturers achieve precise distance measurement and focusing. It can also detect whether personnel are approaching the attendance machine area, measure the distance between the attendance machine and the person, and assist in focusing.
The ranging sensor emits infrared light or ultrasonic waves to the target. The returned measurement values are sent to systems such as cameras, projectors, or thermometers to realize the assisted focusing function.

Infrared Thermal Imager Assisted Focusing
Some infrared thermal imager lenses have a small depth of field and limited focusing accuracy, making it difficult to focus on the human iris. By installing a Benewake LiDAR on the device, the distance from the device to the human iris can be precisely measured to assist focusing. This all-in-one unit offers flexible deployment and can accurately identify individuals even when they are wearing masks. Relying on the precise ranging function of the Benewake LiDAR, the product can quickly focus on the human iris for temperature measurement within 1 second.
Installing thermal imaging automatic temperature measurement and attendance all-in-one machines in office buildings, parks, and other work areas can quickly realize the functions of "iris face recognition + long-distance temperature measurement + attendance recording," eliminating contact infections.
