SWIR Camera Surveillance: Eliminating Haze There’s a deep fog over everything, and you can’t see your hand when you hold it in front of you. The perfect night for a thief to sneak into your factories, make out with whatever they can carry, and get out the same way they came— or is it? Not […]
Infrared Sensors and Optics for Drones An optical drone dips low in front of a herd of antelope, gathering stunning footage for a new documentary. Equipped with advanced optics for drones mounted securely in its unobtrusive body, it is capable of taking high quality imagery even under unfavorable environmental conditions. Later in the evening another […]
Optics for LiDAR and sensing Key Takeaways LIDAR technology has seen huge advances in recent years. Different applications require different types of lasers Custom optics can enable you to create a LIDAR system optimized for your application. Optics for LIDAR and sensing are far more affordable today than they were just ten years ago, and […]
Product Highlights: A microscope magnifies objects, revealing details not visible to the naked eye. It can project the image to the eye or a camera for observation or recording. Avantier’s diverse lineup, featuring achromatic, semi-apochromatic, and apochromatic options, ensures superior imaging quality. With magnifications ranging from 1X to 100X and numerical apertures up to 1.45, […]
Micro-Optics Can a lens be mounted on a surface smaller than the head of a pin, or the full power of complex optical devices be condensed into a package smaller than a fingernail? That’s what micro-optics are about. Microlens Arrays A micro-optic is an optical component or array between a few micrometers and a millimeter […]
Key Takeaways: Optical domes with flanges offer near-zero wavefront error, ensuring exceptional optical clarity in camera systems. Common issues such as distortion, speckle, haziness, and reduced transmission can be addressed with high-quality flanged domes. Selecting the ideal glass dome involves considering application requirements, system performance limitations, manufacturing methods, and material durability. Ground and polished domes […]
Laser Metrology Laser metrology involves the use of lasers to take measurements and test equipment. A versatile set of techniques that enables quick, highly precise, contact-free measurements, laser metrology has an important place in process oversight and quality control. Fields that rely on laser metrology include: Medical device manufacturing Aerospace quality control Automotive engineering Semiconductor […]
SWIR Imaging Short wave infrared light is radiation with wavelengths in the range of 0.9 – 1.7μm. This light can penetrate materials that are impenetrable to visible light, making it ideal for industrial processing and quality check applications as well as for machine vision applications, surveillance, security, and natural resource management. Water vapor, fog, and […]
Key Takeaways Choosing the correct machine vision lens is vital for optimal performance. Understanding fundamental parameters like working distance (WD), field of view (FOV), and resolution is essential. This ensures that the lens meets specific application requirements. Whether fixed or zoom, lenses must align with the chosen camera. Equations like 1/f = 1/do + 1/di […]
Biophotonic Sensors Biophotonic sensors and systems are optical devices that can provide point-of-care diagnostics for medical practitioners and health researchers. They enable researchers to detect, sense, identify, and understand biological systems at the cellular/sub-cellular level, giving them a new understanding of biological processes, conditions, and molecular changes. Biophotonics is a rapidly growing field, and optical […]
