Innovation In AR Lens Coatings: High Quality Coatings For High-Power Lasers
Lens coatings are an essential part of high-power CO2 laser systems. Coatings must protect the lens and allow for the highest levels of optical performance, with low levels of absorption and a long life expectancy. Transparency is another coveted characteristic for use with visible HeNe red laser pointers. The cost/benefit ratio of a coating must also be considered, as well as the environmental impact of the substrates used. For optical...  Continue Reading..

The Light IR product family of lightweight zoom lenses are designed to ensure the smallest, lightest and most compact lens solutions while achieving the highest levels of IR thermal imaging performance for cooled MWIR and uncooled LWIR cameras. They are ideally used for unmanned aerial vehicle payloads, drones, and other handheld devices.

The Ophir Optics Group offers a full range of high-quality OEM and replacement optics solutions for high power CO2 laser and 1μm laser applications. These products are designed to meet the highest industry standards and have been widely tested with outstanding results.

Ophir Optics group develops and delivers a wide range of IR complex lens assemblies with fixed, motorized focus, and zoom lenses to support UAV MWIR and LWIR imaging. These optics are designed to optimize the specific size, weight and power (SWAP) constraints of the UAV payload platforms for military, security and emerging UAV applications.

Automotive night vision systems and ADAS (Advanced Driver-Assistance Systems) that use thermal imaging allow drivers to detect pedestrians and retain a clear view of the road ahead, even when vision is obstructed by environmental conditions such as darkness, smoke, or fog. For maximum performance and minimal collision risk, these systems must achieve high accuracy and allow for long distance object detection. The key to meeting these requirements is the use of high sensitivity and high-resolution optics – such as Ophir’s athermalized lenses.

Ophir Optics Group delivers new optimized IR optics designs that match the needs of upcoming 10 – 12 μm uncooled detectors that must meet superior SWaP standards, enable a reduction in the size of the optical system, and provide a shorter focal length and a longer detection range.

Ophir Optics Group offers a family of non-ITAR MWIR f/4.0 zoom lenses with focal lengths ranging from 15 – 300 mm or 45 – 900 mm. These high-performance zoom lenses are offered with a series of extenders for superior DRI ranges, making them ideal for long range observations and surveillance system applications. The 45 – 900 mm f/4.0 zoom lenses provide the highest focal length, with a detection range of up to 24.7 km.

Ophir Optics Group's array of IR long-range zoom lenses offer outstanding detection, recognition, and identification (DRI) ranges ideal for commercial, surveillance, and homeland security applications. They are available for use in various FPA formats, including high-definition XGA and SXGA formats, with crisp clean images over full zoom and MTF close to the diffraction limit.

Schneider Optics offers the Macro Varon and Macro Varon with a beamsplitter for PCB/ FPD/ OLED/ LED inspection, flat glass inspection, quality control, wafer inspection, line scan, and other web and surface inspection applications. They are ideally suited for 12k line scan with pixel sizes from 3.5 μm up to 5 μm.
