Food & Beverage As a reliable analyzer for wine, must and juices, the ALPHA II has found widespread use across the world. It analyzes sugar, alcohol and other contents in an efficient, fast and affordable manner. It is also used in FOA (foreign object analysis), identifying unknown contaminations in processed or packaged foods.

When stitching images together, lens distortions can cause mismatches and inconsistencies between two images. As a result, it takes a lot of work to merge them seamlessly.

Multireflection-ATR The Multireflection-ATR is a special tool for the analysis of pastes, gels and liquids. Its horizontal, multi-reflection ZnSe crystal offers the extra-high light throughput needed for the analysis of low concentrated sample components. Example applications are the analysis of APIs in pharmaceutical formulations or quality control of tar/bitumen. Watch our video to learn more.

Art restoration & Artefacts & Jewellery Historical works of art and jewellery have one thing in common: both are precious. The ALPHA II is applied in the restoration of historical paintings, buildings and artwork, and is also an affordable tool for the identification and type classification of diamonds and other gemstones.

Polymers The ALPHA II is intensively used in the polymer industry. The ALPHA II inspects incoming raw materials, test finished products and investigate coated surfaces. One of the biggest user benefits, are Bruker's dedicated, up-to-date and ready-to-use methods to identify and characterize recently introduced polymers and fillers.

To solve this problem, Reolink introduces unique dual-image stitching algorithms. This algorithm ensures that two separate lens distortions match and align properly during stitching. This algorithm will come with Reolink's upcoming 16MP security camera, the Duo 3 PoE. If you are curious about this technology, join Reolink at the CES 2024. This Duo 3 camera will be presented at this annual technological event. Don't miss this opportunity!

The answer is yes. Correcting lens distortions is crucial for image stitching techniques. Lens distortions on the edge of images can cause misalignment between separate images. Lens distortion correction might be the first step to creating seamless panoramas.

Pharmaceuticals Early on, Bruker decided to design their software with the needs of pharmaceutical companies in mind. Therefore, OPUS and OPUS Touch follow the ALCOA+ principle and are 100% compliant with all major pharmacopoeias and of course 21 CFR part 11. Whether locally or on a server, the ALPHA II ensures data integrity and security.

Reflection modules As the ALPHA II works facing in any direction, so can your reflection measurements. Point the instrument on ceiling murals to analyze ancient paint, or place large polymer work-pieces in front of the instrument. Our reflection modules allow contactless and non-destructive FT-IR analysis of bulky and structured samples. The integrated video camera helps finding the area of interest.

Lens distortion effects refer to alterations or abnormalities in images caused by the characteristics of a camera lens. Some common lens distortion effects include barrel distortion, pincushion distortion, mustache distortion, etc.

Profile-based correction is another good way. Many photo editing software and plugins have built-in databases of lens profiles. These profiles contain information about special lenses and their existing distortion. The software can use this data to apply corrections automatically based on the known lens.

Industrial Manufacturing & Automotive Infrared spectroscopy is a decisive tool in industrial applications, whether automated and in-line or manual and off-line. The ALPHA II is used to investigate coatings, used oils, finished products and much more.

DRIFT Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) is a special IR sampling technique. Our DRIFT module was designed for easy sampling and high spectral data quality. This results in an unmatched time-per-analysis for FTIR diffuse reflection measurements of a variety of solid samples: powders, inorganic material, gemstones, papers, textiles and others.

Fixing lens distortion requires a series of tools and techniques. If you are a professional photographer, you can use a lens distortion grid to fix distortions on professional-level photo editing software. Suppose you just want to fix lens distortions of photos captured by your phone. In that case, you can download a photo editing app on your mobile phone and look for the "Lens Correction" function to fix lens distortions.

Understanding the basics of lens distortion, particularly in wide-angle lenses, is crucial for realizing optimal image quality and panoramic field of view. Effective lens distortion correction techniques can help create cohesive and visually accurate images. Reolink, a global innovator in security cameras, also introduces its unique dual-lens image stitching algorithms to correct the lens distortions between images.

In photography and computer graphics, a lens distortion grid can be used for visualizing and correcting distortions caused by camera lenses. It consists of a grid pattern or a checkerboard pattern photographed or rendered using a specific lens.

Modules for gas analysis Gas analysis grows more important. Bruker offers dedicated gas analyzers, like the OMEGA, but of course, the versatile ALPHA II can also be equipped with dedicated gas sampling modules for transmission IR spectroscopy. Different pathlengths are available addressing the needs of simple quality control of gases up to the detection of lowly concentrated gas components. Heating options are available.

Environmental One of the many environmental applications is the analysis of microplastics. Particles >500 µm are placed onto the ALPHA II, and a special “high pressure” accessory guarantees spectral quality. Additionally, the ALPHA II is also used to analyze soils as well as other environmental pollutants like oil and grease in water.

Operating the ALPHA II is meant to be effortless and straightforward, regardless of whether you use the integrated touch PC or an external computer. On one hand, OPUS TOUCH offers you minimal training time for new users and an accelerated analysis experience. In addition, the optional touch PC further reduces the overall footprint of the system, making it easier to transport the instrument. On the other hand, the use of an external PC offers you an even richer feature set that leaves nothing to be desired from the most advanced users. The desktop version also features guided workflows for standard tasks, supporting FT-IR beginners.

Camera lens distortion refers to the subtle changes or alterations in an image captured by a camera lens compared to how the human eye perceives the same scene. It's an optical anomaly that can cause straight lines to appear curved or bent and objects at the edges of an image to appear slightly stretched or compressed.

Multiple quantification methods facilitate reporting and documentation of results.

Lens distortion refers to the imperfections or alterations in how a lens captures an image, causing straight lines to appear curved or objects to be warped towards the photo's edges. With the advancement of photography technology, wide-angle lens distortion expands the image dimension. To obtain perfect images, photographers need to apply lens distortion correction techniques.

Eco-ATR This ATR combines cost-efficiency with great performance. It features a large, high-throughput ZnSe crystal that is suitable for most applications that do not involve very hard or acidic samples. A Germanium ATR crystal is also available (e.g. for the analysis of black polymers or surface sensitivie FT-IR). Both are easy to apply, convenient to clean and analyze solids or liquids. Watch our video featuring the Eco-ATR.

Lens distortion can also impact image stitching when combining several images to create a panoramic image. Wide-angle lenses have also been incorporated into security cameras. However, lens distortion can become an obstacle to the panoramic view of these cameras, especially for dual-lens cameras, because dual-lens cameras require techniques to stitch images captured by two lenses together.
