Over the past decade, chalcogenide glass substrates have become a preferred choice for IR optics. They offer many advantages that legacy materials such as germanium, silicon, and others simply cannot match. Because chalcogenide glasses are softer and prone to scratches, a protective layer is critical. A diamond-like carbon (DLC) coating is ideal for its extreme durability to withstand the harshest environmental conditions. However, coating chalcogenides with DLC is a notoriously challenging endeavor plagued by adhesion problems and coating defects. IR expert Ray Pini compares chalcogenides' properties to more traditional substrates to understand their growing popularity and delves into the adhesion challenges they present throughout the coating process. He shares how EMF has successfully produced dependable, long-lasting DLC coatings on chalcogenides at scale, along with top tips to ensure your coating partner has the capabilities and capacity to deliver the precision coating solutions you need. Have questions about DLC on chalcogenides or other substrates…or other coatings? Our team is standing by. Please contact EMF at websales@emf-corp.com or +1-800-456-7070.

Introducing Ophir® LightIR16-180mm MWIR f/3.6 continuous zoom lens, the newest addition to the successful LightIR family of lightweight, long-range, motorized continuous zoom lenses. The LightIR 16-180mm f/3.6 is a compact, thermal imaging lens optimized for smaller size 10µm pitch VGA FPA detectors. It features a folded optics design that significantly reduces the length of the lens and, therefore, the overall size and weight of the optical system in which it is incorporated. The lens is 65% smaller than existing MWIR 10µm VGA lenses. This makes it ideal for the demanding requirements of reduced SWaP and small gimbal thermal imaging applications, including drones and tactical UAV IR cameras, and micro-/mini-tactical payloads in the commercial, homeland security, and defense industries. The LightIR 16-180mm f/3.6 folded zoom lens addresses the new market shift toward smaller size detectors, with its disruptive combination of size, weight, range capabilities, and cost, the new zoom lens is an enabler for advanced drone, UAV, and small gimbal thermal imaging applications. The folded optics design enables long optical lengths, which produce a reduced sensitivity to tolerances in compact configurations that incorporate fewer optical elements. The innovative design also enables near diffraction-limit performance in harsh environments and addresses such challenges as LOS stabilization and athermalization. At only 460gr, it is one of the lightest weight, continuous zoom lens on the market, maintaining sharp focus over the entire zoom range with mechanical/ electrical interface assures easy integration into camera systems.

Typical optical materials for IR applications such as Ge and ZnSe require unique polishing techniques to meet high end optical specifications. We will present two techniques: OptoTech Reverse Technology and HydroSpeed Polishing. By using these methods, we will show how we can polish a lens with an even pressure distribution giving extremely low deformation of the lens giving much better fitting accuracy of the surface.

Chalcogenide glasses offer high transmission for short to long wave infrared applications, while holding key advantages over germanium, such as lower temperature coefficient of refractive index and more flexible shaping solutions. These unique properties require non-traditional optical metrology techniques where few standards are currently available. In this video, the standard material qualification practices for SCHOTT's IRG line of chalcogenide glasses will be discussed. The processes for evaluating transmission, index, and internal quality have been optimized to accommodate high volume glass production, while ensuring high quality materials are maintained at high confidence levels.

Teledyne Imaging, part of Teledyne Technologies, has released a new and innovative CMOS sensor technology, LACera™. LACera, large area CMOS, is a significant step forward in CMOS capabilities for advanced imaging which will enable the next generation of scientific discovery. Exclusively developed by Teledyne Imaging, LACera advanced imaging technology draws on Teledyne's decades of expertise in CMOS sensor and camera development. Applications as diverse as next generation genomics, astronomical photometry, ultra-high-resolution x-ray and electron imaging require CMOS sensors and cameras with low light sensitivity and speed. LACera CMOS technology delivers greater than 90% quantum efficiency and proprietary low noise architecture with up to 18-bit readout – a combination of performance not previously available in wafer scale sensors. The first implementation of LACera in a commercial product is found in the COSMOS™ family of scientific cameras. COSMOS delivers deep-cooled, low-noise performance on a multi-megapixel scale, with global shutter, 18-bit readout, and glow reduction technology. COSMOS addresses many of the challenges of today's CMOS technology by maintaining performance when scaling to larger formats and combining speed and low noise. COSMOS is available from 3k x 3k to 8k x 8k sensor sizes, with large 10 micron pixels for maximum field of view. COSMOS large array cameras provide >90% peak quantum efficiency for high sensitivity and over 50 fps for capturing dynamic events. Other benefits include 0.7 e- read noise for detection of faint objects, and deep cooling to ensure low dark current. An advanced pixel structure allows for true global shutter alongside back-illuminated CMOS. This product introduction session will provide detailed information about LACera and COSMOS.

TOPTICA's TOPO, a cw-OPO, tunes from 1.45 - 4.00+ µm with high resolution and narrow linewidth. All tuning is computer-controlled, allowing for automated tuning. It is the ideal light source for molecular spectroscopy, mid-IR photonic device characterization, and near-field microscopy. In this presentation we will describe the system and demonstrate its ease of use: We will use our automated tuning routines to stabilize the TOPO idler to a target wavelength, and demonstrate our wavelength scanning software which scans the TOPO over a user-defined range.

In the manufacturing process of IR optical systems, e.g. for security and defense applications, the non-transparency of the lens materials in the visible spectral range (VIS) leads to special requirements on the assembly and test equipment. Whereas the assembly process in many cases can be accomplished by using cost-effective VIS equipment, other testing steps require a test bench specifically designed for IR. This is particularly true for the final inspection and when the root cause for out-of-spec assemblies needs to be identified. Here a solution for the full opto-mechanical characterization in the infrared is required. In this contribution, we present solutions how to make the manufacturing process of IR objective lenses most efficient by using adequate techniques for centration-based alignment testing, IR MTF analysis and non-contact determination of center thicknesses and air spacings.

Optical system design requires an understanding of environmental conditions and requirements of the finished product, as well as properties of the optic itself. Selecting the right optic will maximize lifetime and performance of the optical system.
