TILO stands for 'Thermal Imaging Light Optic' and was developed as thermal imaging goggles. With a length of 4–6cm and a weight of 100g–150g, it is the smallest and lightest thermal imaging goggle in the world. It can be worn on helmets as well as caps and headbands. At present, there is no comparable device with such high technical performance in such a small design. Its performance is comparable to larger handheld systems. For example, the TILO-6 features a thermal sensor with a high resolution of 640x512 pixels. In addition, all devices in the series are equipped with high-performance LEDs. Some TILO models have a thermal resolution of at least 20mK. This means that temperature differences of less than 0.02°C can be displayed, which is a huge advantage in poor weather conditions or indoors.
Eyepiece optics
With conventional linear optics, the TILO would not be the shortest thermal imaging goggle in the world. That is why a specially folded eyepiece optic was developed for the devices, which is also very tolerant in terms of eye position. Both eye relief and eye position are tolerated over a wide range. This is an important prerequisite for use as thermal imaging goggles on a tactical helmet. Thanks to the maximum possible eye relief of 25 mm, protective eyewear can also be worn comfortably between the eye and the TILO.
