Far-infrared sensors have become increasingly important in energy management through heat detection and monitoring in recent years as public awareness of environmental issues has grown. The car industry’s increased desire for autonomous driving technology has led to an increase in the usage of such sensors, which can identify faraway humans and animals at night when normally visible light cameras can’t. As a result of these circumstances, far-infrared sensors are becoming more pixel-rich and less expensive, and the lenses used for these sensors are also required to have a higher added value.
Due to its low transmittance, cheap-cost silicon, which has been widely utilized as the lens material for far-infrared sensors, is not appropriate for large pixel counts, hence high-transmittance germanium spherical lenses are commonly used as the number of pixels increases. As the pixel count rises, the effect of aberration caused by a spherical lens becomes more obvious. A combination of numerous spherical lenses and an aspherical lens will be required to counteract this effect, increasing cost and size.
The global high precision asphere market size is expected to reach USD 34.45 Billion in 2028 and register a steady revenue CAGR of 6.4%, High Precision Asphere Market Size – of USD 20.82 Billion in 2020, Market Growth – at a CAGR of 6.4%, High Precision Asphere Trend – Technological developments in high precision asphere

New technologies for high-precision aspherical lenses suited for far-infrared optical systems, based on the glass molding process pioneered for visible light aspherical lenses for cameras, are being developed to overcome this challenge.
Panasonic recently announced the discovery of a method for mass-producing far-infrared high-precision aspherical lenses, which will improve camera and sensor performance. These lenses are made of chalcogenide glass, which provides excellent far-infrared transmission. Panasonic can now offer a wide range of lenses, including a diffractive lens, the world’s first fully hermetic frame-integrated lens without glue, as well as inexpensive costs (approximately half of the company’s previous method) owing to the newly developed glass molding and mold processing technologies. By mass-producing low-cost, high-quality far-infrared aspherical lenses, the company will contribute to the widespread use and increased performance of far-infrared sensor modules.
Both the plastic aspherical lens and the glass aspherical lens markets have experienced exponential growth. End-user businesses have been able to expand the capabilities of their goods without sacrificing earnings due to aspherical lenses. Industries are turning to aspherical lenses to get more efficient and effective technology that avoids the challenges created by high index spherical lenses’ diffractive aberrations. The car industry is currently making extensive use of aspherical lenses. The rapid expansion of the automotive and mobile phone industries presents significant growth prospects for the high precision asphere market shortly.
