Adaptive Cruise Control

ADAS (advanced driver assistance systems) are taking on more and more responsibilities in the automotive industry, improving comfort and safety, similar to ACC systems. Without the use of optical filter, highly advanced ADAS, autonomous driving is not possible. To ensure that the ACC and ADAS systems are working properly, an excellent, durable and reliable optical filter is essential.

Autonomous Vehicles

Optical signals are mostly used for communication and control between autonomously operating robots and vehicles. Due to the stringent requirement and standards, NIR and IR wavelengths are used for the sensors integrated.

GF Tech’s well-controlled coating technology and filters manufacturing capability have successfully produced different filters with steep edges and blocking >OD4.

Gesture Recognition and Control

Gesture recognition is a technology that reads and interprets hand gestures that uses TOF (time of Flight) technology. In the automotive sector, this capacity enables occupants to communicate with the car, often to operate the infotainment system without touching any screens or buttons.

It requires strict control of the illumination wavelength range that can pass through. To increase contrast, a very deep blocking is required to totally filter off ambient light near to the pass range.

Head-Up Displays, Instrument Clusters & Displays

Any transparent display that shows data in a car without requiring users to look away from their regular viewpoints is referred to as an HUD (Head Up Display). It is of great use in assisting drivers to get navigating and car info quickly without looking away from the road condition.

The manufacture of head-up display components makes use of contemporary thin-film coatings and coated optical components such as Angle AR (Anti Reflection) coating, BS (Beam Splitter) coating and mirror coating.

Night Vision Systems

When driving at night or in poor lighting conditions, night vision aids enable drivers to see people, objects, and the route of the road at full beam distance without blinding incoming vehicles.
It frequently makes use of infrared imaging sensors to locate and capture photographs of objects that are challenging to view when there is not enough visible light.

GF Tech is able to develop vision filters that significantly help to improve the visibility during night or bad lighting condition.

Scanning LiDAR and Solid State LiDAR

Autonomous vehicles must have a precise understanding of their surroundings. It’s critical to recognize the presence of other vehicles, pedestrians, and other relevant impediments in normal traffic situations. High-resolution three-dimensional models of landscapes and building objects are produced using the widely used remote sensing technique known as Lidar (light detection and ranging). Lidar measures distances to the ground or other landmarks using laser pulses.

It has uses in many different fields, including archaeology, climate monitoring, city planning, meteorology, mining, and crime scene reconstruction. And many more thanks for its adaptability and high resolution.

GF Tech is committed to continue the development of our coating solutions and optical components which LiDAR a mature and widely-used sensor technology in our future.

Fluorescence Microscopy

When using a fluorescence microscope, chemicals that emit fluorescence are combined with the light microscope’s magnification abilities. A high-intensity light source is used in fluorescence microscopy to excite a fluorophore, a fluorescent molecule, in the sample being examined.

Bandpass, shortpass, and longpass emission filters, as well as dichroic beamsplitters, are all included in the fluorescence filter sets that GF Tech offers. A range of wavelengths are selected to match the excitation and cut-off wavelengths of the fluorescent dye. Standard substrates are covered with all-dielectric low absorbing hard coatings to create a quick transition between high transmission and deep blocking down to OD5 or OD6. The high transmission of pass band, steef slope and precise cut off of excitation filter and precise cut on of emission filter ensure high quality images in terms of sharpness, contrast and brightness.

Heat Protection Filter Medical Lighting

In the process of illumination, certain amount of heat is also dissipated, which harmful radiation is also within the dissipation.

Therefore, heat protection filter is critical in illumination devices. These filters combine an extremely high transmission in the visible region with a sharp transmission to impede transition in the IR band.

GF Tech offers a variety of harmful radiation blocking filters.
