Approaches To High Performance SWIR Lens Design

G&H's A&D Business Development Manager, Trevor Cook discusses approaches to high-performance SWIR lens designs, by explaining technical challenges in more detail, addressing effective solutions.

  • 4 Advantages Of Optical Active Alignment

    Optical alignment and micro-optic positioning are challenging, time-consuming processes. Tiny positional variations in photonic and optical manufacturing can mean the difference between success and failure. This article discusses active alignment as a technology that improves the performance, profitability and yield in manufacturing advanced optics and photonics components for the modern era.

  • Advanced Fiber Optics Enhance Visualization For Robotic Surgery

    For robotic surgery, light guides made from specialty glass fibers can deliver the high-quality light needed to provide a realistic and clear view of the surgical field.

  • The Application Of WDM Channel Skip Filters

    Channel skip filters enable precision band splitting in telecommunications options, offering improved performance over edge pass filters at a cost adaptable to any project budget.

  • Lens Condition Analysis: Exploring Lens Failures And Their Causes

    This white paper gathers customer feedback on cases of lens condition analysis and captures their experience in operating their laser systems.

  • The Power From The Mirror

    High-power lasers can only be as strong as their optical components allow. Thus, the further development of laser technology depends crucially on the development of complex coating systems with a high damage threshold.

  • Laser Forensics: The Invisible, Revealed And Measured

    According to the developers at Scanovis, brushes, powder and chemicals will soon be tools of the past for securing evidence at crime scenes. The company has developed a laser-based solution that, among other things, uses IR laser radiation to detect fingerprints at the scene of a crime, quickly making them visible in a 3D scan and recording them digitally. Decisive factors for this technological breakthrough are the precision of the results delivered by the laser scanner and the easy handling of the system. But how to adjust the optics of a system using a low power laser in the mid-infrared spectrum? Working together with Ophir's measurement experts, the company was able to combine different measurement methods to this end.


  • With the ability to be utilized in many applications including materials, life sciences, and semiconductor, the PureFocus850 Laser Autofocus System by Prior Scientific is fast and easy to set up and use. This system also features the ability to autofocus on different interfaces including slides, glass bottom dishes, flow chambers and many more.

  • Applied in many fields, including avionic and space communications, biomedical instrumentation, fiber laser systems, industrial micromachining, interferometry, LIDAR, medical diagnostics, optical coherence tomography (OCT), sensing, and telecommunications, G&H's Single-Mode Couplers play a vital role in aligning and marrying individual cable fibers.

  • G&H designs and manufactures custom modules including fiber assemblies of passive and/or active optical components. Customers sourcing fiber optic assemblies are looking to reduce time to market and development costs. 

  • G&H NightCrawlIR™ series utilizes unique aperture specific foreoptics and a modular base to maximize performance, while staying budget-friendly. These lenses are purpose-built from the ground up for the demands of high resolution applications.

  • Ophir's family of LightIR lenses are compact yet offer high-performing features. While optimized for stabilized payloads, the 680389, 680314, and 680386 products are also suitable for a wide range of applications.

  • The compact, yet powerful 680389 from Ophir is a Folded-Optics Zoom Lens that features a motorized, continuous zoom functionality. This product is designed for reduced SWaP MWIR 10μm pitch VGA detectors.

  • LASER COMPONENTS has developed a new optics layer design that has the ability to separate the polarizations of three wavelengths simultaneously. These new trichroid thin-film polarizers can be used to combine linearly polarized laser beams from several sources, even if they have the same or different wavelengths.

  • The SupIR 50-1350mm f/5.5 is a motorized continuous zoom lens with the longest available focal length and zoom ratio. It is designed for use in UAV payloads with its excellent detection range of more than 25 km.
