When it comes to long-range, multispectral optical systems, large mirrors play an integral role; there are tens of thousands of optical units containing large mirrors around the globe. With minimum diameters starting at 200 mm, the largest mirrors range from 8.2 m in diameter (single mirrors) to over 10 m (segmented). They take many shapes — spherical, aspheric, parabolic, or freeform — and are used for a wide spectrum of light, including visible, UV, and IR. Over the last 10 years, optical systems with reflective elements have been used by system integrators in the defense and aerospace industries, in surveillance and monitoring, and in certain commercial applications. For example, large mirrors may be integrated into the optical systems of large unmanned aerial vehicles (UAVs) in long-distance aerial monitoring of agricultural field temperature using IR. The most recognized applications of large mirrors have been in the aerospace industry, for satellites and long-range telescopes.
Paris, France, June 12, 2018 – MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® SupIR family of compact infrared lenses, designed for use in 10-12μm pixel size uncooled cameras, at Eurosatory 2018. The new collection includes 11 lenses optimized to meet reduced size, weight, and power (SWaP) standards. They deliver high MTF and range from 2.4mm f/1.0 athermalized fixed focus, to the new LightIR 15-75mm f/1.2 motorized continuous zoom, with fields of view (FOV) from 91.9 to 2.4 degrees. The lenses work with a variety of camera formats, including VGA, QVGA, and XGA. They are targeted for use in air, marine, and land applications, such as unmanned aerial systems (UAS), and unmanned aerial vehicles (UAV), perimeter surveillance, handheld devices, and drones.

(NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced the Ophir® LightIR™ 15-75mm f/1.2 zoom lens, a new member of the LightIR family of lightweight, continuous zoom lenses, at Eurosatory 2018. The LightIR 15-75mm f/1.2 is the first compact, thermal imaging lens optimized specifically for uncooled 10-12μm pixel size long-wave infrared (LWIR) detectors. It is designed for use in a wide range of reduced size, weight, and power (SWaP) applications including unmanned aerial systems (UAS), unmanned aerial vehicles (UAV), aircraft vision systems, drones, and handheld applications such as thermal goggles.
Large mirrors are a critical aspect of numerous optical systems, and are used in a wide variety of important applications. For the production of high performance large mirrors, optical manufacturers are tasked with the challenge of meeting a strict set of requirements
When it comes to long range multi-spectral optical systems, large mirrors play an integral role. Such optical systems are used for defense applications, surveillance and monitoring, as well as for certain commercial applications. For example, large mirrors may be integrated in the optical systems of aircraft like large UAVs. An interesting commercial application is the long distance aerial monitoring of agricultural field temperature using infrared. The most commonly recognized applications of large mirrors are in the aerospace industry – for satellites and telescopes.
Recent UAV system developments have drawn attention to the optical needs of the UAV industry. As detectors become larger in size and smaller in pixel size, UAV optics with higher MTF values and lower F# are the key to maximizing imaging performance.
The unmanned aerial vehicle (UAV) industry is growing rapidly, with Teal Group analysts estimating that worldwide UAV production will total $135 billion in the next ten years1. When equipped with high performance EO/IR camera payloads, UAVs, also known as drones, lend themselves to a wide range of imaging applications.
MKS Instruments, a global provider of technologies that enable advanced processes and improve productivity, has introduced the Ophir LightIR compact, continuous zoom lens.
LightIR is a lightweight, infrared (IR) thermal imaging lens for cooled detectors in commercial applications, including drones and unmanned aerial vehicles (UAV), marine and handheld devices.
Andover, MA, May 1, 2017 MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, will announce the Ophir® LightIR™ compact, continuous zoom lens at the XPONENTIAL show for Unmanned Systems and Robotics, May 8-11, 2017. LightIR is a lightweight, infrared (IR) thermal imaging lens for cooled detectors in commercial applications, including drones and unmanned aerial vehicles (UAV), marine, and handheld devices.
LightIR is a compact, high performance, F/5.5 zoom lens with a focal length of 20-275mm. At only 264g, it is the smallest, lightest weight, continuous zoom lens on the market. It maintains a very high zoom ratio over the entire zoom range. A single board controller provides a micro switch option to select between RS485 and RS232 communications.
Jerusalem, Israel, 7 February 2016 Ophir Optics, a leading designer and manufacturer of precision infrared and laser optics, will highlight its high-powered SupIR 40-300mm F#1.5 Uncooled LWIR motorized continuous zoom lens at Photonics West, which is to be held at the Moscone Center in San Francisco from 13 to 18 February.
The main applications for this compact and easy to use, state of the art, zoom lens are; border patrol, surveillance, policing, high-end maritime and in mid to large size airports.
The highly sensitive 17 micron detector in the lens allows the detection of a 2.3 x 2.3 meter vehicle at 18 km, according to FLIR 92 Johnson criteria. It delivers the ability to recognize the vehicle at 9 km and the ability to identify it at 3 km.
