Aberration: an unwelcome departure from the normal, usual, or expected. Most images are imperfect. Image processing software is able to detect even the slightest distortions in an image that appears ideal to the human eye. This distortion results from optical aberrations, which is the inability of a lens to replicate ideal mathematical performance. Lens designers compensate for optical aberrations with specialized optical coatings and additional lens elements, which add cost, size and weight to the final product.
Imaging systems work by focusing light that passes through a lens (or several lenses) and falls on a sensor or a screen. In poorly-designed optical systems it is common to see distortion or poor focus in some or all regions of the image. In this article we discuss the causes of optical aberrations, the most common types, and offer some ways to avoid them. Fused Silica. The Dynasil family of companies delivers an extensive range of photonics-based products and capabilities.
But Dynasil itself is a product of its workforce. In this Q&A, we meet Dino Monaco, Operations Manager at Dynasil Fused Silica. Q: Let’s start with you telling us about your role. Dino: As the Operations Manager at Dynasil Fused Silica (DFS), I essentially oversee the operations of each customer project – from the moment an order is received, through its fabrication, to final inspection and shipping. DFS operations are oriented around teamwork, same as many small companies. IR Window. Hilger Crystals manufactures infrared windows and optics using custom grown optical crystals.

It’s ability to grow synthetic crystals in large volumes and to incredibly demanding specifications is further boosted by their close collaboration with customers — a practice that has proven successful from prototyping new research to wide-reaching commercial engagements. Diamond Like Carbon Coating. Diamond-Like Carbon (DLC) Diamond Like Coating Diamond-like coatings are used across many industries in magnetic storage disks, car and engine parts, biomedical implants, and cutting and forming tools.
They are a preferred choice in defense and security applications where environmental factors necessitate an anti-reflective coating with high durability and ability to withstand harsh conditions. While inherent property concerns of a diamond-like coating, such as compressive stress, can be controlled with process input settings, the real Achilles heel of a DLC coating are Pinholes – common to systems that coat down. Echelle Grating. Dental Photography Mirrors. Holographic Diffraction Grating. Diameter Optical Blanks. Optical Coating Solutions. Optical Coatings Founded in 1936, Evaporated Metal Films (EMF) was the first company in the US to offer thin film coatings.
For over 80 years, EMF has continually expanded and refined its capabilities to deliver custom precision optical coatings. Custom Developed Scintillators. Scintillators are a group of materials that luminesce when exposed to ionizing radiation.
In layman’s terms that means these materials emit light when they absorb particles or electromagnetic waves that create “free” electrons in the material. While this may be viewed as a seemingly dry and uninteresting definition, scintillators enable a plethora of exciting and very necessary applications ranging from personal radiation detection to the detection of dirty weapons, and medical applications such as treating cancer. In this series of posts, we’ll explore the world of scintillation, starting at the most basic – how scintillation materials respond to radiation. While scintillators come in many forms – gas, liquid, solid, and both organic and inorganic – we will focus on inorganic crystal forms, a sweet spot for us since Hilger Crystals has grown crystals since the mid 1930’s.

Scintillation Crystals Scintillation Crystals Hilger Crystals is a leading manufacturer of a wide range of scintillation crystal materials for X-ray, gamma-ray and neutron detection and X-ray imaging.
Scintillation crystals are used in detectors to convert X-rays or gamma rays into light pulses that are subsequently detected by either a Photomultiplier Tube (PMT) or a Silicon Photomultiplier (SiPM). Pixelated crystal X-ray imaging arrays can be either linear or two dimensional with individual pixels as small as 0.5mm depending on material and thickness. Hilger Crystals produces an extensive range of scintillation crystals carefully selected for their high density and brightness, excellent light output, and short decay constants.

Buy Bonsai Tree. The World’s Oldest Bonsai is a Ficus retusa that’s on display at the Crespi Bonsai Museum in Parabiago, Italy.
It’s estimated to be well over 1000 years old, so for context, roughly 3 years older than National Treasure Betty White. Luigi Crespi spent 10 years negotiating the purchase of the tree, which was shaped for generations by Chinese Bonsai Masters and then by Japanese Master Shotaro Kawahara when it arrived in Italy in 1986. The World’s Most Expensive Bonsai Tree is a 300-year-old White Pine that sold for $1.3 million at the International Bonsai Convention in Takamatsu, Japan.
The tree is known for its exceptionally impressive size and quality, but so are ours, and most of our trees are $65 with Free Shipping, so…. This is wild ~ a Japanese White Pine Bonsai, planted in 1625 and cared for by five generations of custodians, survived the 1945 bombing of Hiroshima despite being just two miles from the detonation site. Bonsai Tree Near Me. First of all, and probably most importantly, it’s impossible to be sad when you’re around a Bonsai Tree.
Feel free to try, but all you’re going to be is sad that you can’t stop feeling so happy when you’re near a piece of living art in a tiny pot. Bonsai boost mood, productivity, concentration and creativity, so if they came in pill form they’d cost twelve billion dollars each without free shipping (our shipping is free by the way). If there’s a room in your house or a space in your office that doesn’t immediately look fourteen thousand times better with a Bonsai tree in it, it’s time to burn the place down. It could be haunted, it might be built on a cursed burial ground, it might be in Ohio, but rest assured, something is very bad and it’s time to leave. Gift Bonsai. Bonsai Tree Kit. Easiest Bonsai Tree. Color Correction Filters. Wire Grid Polarizer. Wire grid polarizers, as the name suggests, are polarizing elements that use arrays of fine metal wires to selectively transmit p-polarized light and reflect s-polarized light.
Due to this function, they are used as linear polarizers and polarizing beam splitters. Wire grid polarizers can be fabricated with different metals like aluminum or gold on a range of substrates. This provides great design flexibility to produce polarizers that can operate in different spectral regimes, such as UV, visible, and IR. Optical Material Fused Silica. Optical Material: Fused Silica is the fourth in a series of blog posts that aims to highlight the various optical materials used to design and manufacture optical components for the photonics industry.
Although float glass [featured in a recent blog post] is the most common material used in optical components, there are several demanding applications that require superior material characteristics such as high chemical purity, high-temperature resistance, high transmission, chemical inertness and low co-efficient of expansion.
In such cases, alternative material choices are needed, and fused silica (SiO2) is a predominant candidate that satisfies these strict optical requirements. Fused silica is an ultra-pure, amorphous form of glass that is made from high purity silica. Typically, the concentration of silica is greater than 99.9999% with miniscule quantities of other metal oxides. Fabrication. Optical Material Plastics. Optical Material: Plastics is the third in a series of blog posts that aims to highlight the various optical materials used to design and manufacture optical components for the photonics industry.
Although glass has been the traditional choice for optical components, the advent of plastics transformed and expanded their application potential in modern optics. Plastics have several advantages over glasses and ceramics, and in many recent applications have served as a formidable replacement for traditional optical materials. From a chemical perspective, plastics are essentially polymers of hydrocarbons. They are extensively used as packaging materials, and functional or protective components in medical equipment, construction tubing, contact lenses, fabrics etc. Optical Materials. Optical Material: Ceramics is the second in a series of blog posts that aims to highlight the various optical materials used to design and manufacture optical components for the photonics industry.
Ceramics: Introduction The word ‘ceramic’ is derived from the Greek word keramos meaning pottery. Ceramics are most commonly associated with earthenware, porcelain and stoneware, which have been used for several thousand years and are still remain popular today. However, did you know that ceramics are a class of exceptionally versatile materials and have many more applications beyond pottery? Today, ceramics are used in virtually every industry from construction (cements and tiles) to electronic components (insulators, semiconductors), and optics (optical windows, lasers, electro-optics). Anti Reflective Coating. Optical Material: Float Glass is a first in a series of blog posts that aims to highlight the various optical materials used to design and manufacture optical components for the photonics industry.
Float Glass Glass is a category of inorganic and amorphous materials that are irreplaceable components in many applications from architecture and art to automobiles and high-end optics. Glasses have been around for over 5,000 years but with increasing industry applications and mass production, the demand for scalable, high-quality, distortion-free glass became a major topic of research in the 1950s.

Introduction to Anti-Reflective Coatings An AR coating is an optical coating applied to a surface to reduce the amount of light reflected off the surface. It is typically used for optical applications where the coating is applied to the front of an interface between air and a lens, glass barrier, or mirror. AR coatings are designed to maximize the amount of light that transmits or enters the surface while minimizing the light lost to reflection. Metallic Coatings. Plate Beamsplitters.
