OPTICS WHITE PAPERS
Optical Coatings InfographicOptical Coatings Infographic
Automated Solutions for SAE Standard HUD MeasurementHead-up display (HUD) technology is one of the largest growth areas in the automotive market, and standard measurement criteria are rapidly being defined to evaluate augmented projections for visual quality and safety of HUD systems. This paper...
Five Signs that a Photometry-Based Imaging System is the Right Choice for Your Inspection ApplicationPhotometric imaging solutions bridge the gap between machine vision systems and true human vision, offering consistent, quantifiable data for automated processes that matches the visual acuity of human inspectors. Learn the limitations of standard...
Fractional Pixel Method for Improved Pixel-Level Measurement and Correction (Demura) of High-Resolution DisplaysAs display resolutions increase, imaging systems are challenged to continue to provide accurate pixel-level measurements while applying increasingly limited relative imaging resolution during single-image analysis (necessary for production...
Introduction to Optical ReplicationOptical replication is a method of re-producing a reflective surface with the identical surface figure and optical performance of a master part. This process facilitates low- to large-volume production of various optic shapes, such as concave and...
Methods for Measuring Display Defects and Mura as Correlated to Human Visual PerceptionHuman vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production environments. Traditional methods for automated defect...
Using Imaging Colorimeters to Correct OLED, MicroLED, and Other Emissive Displays for Production Efficiency and YieldsImaging colorimeters can improve OLED and microLED display production by ensuring visual quality of displays — measuring brightness and color uniformity at the pixel and subpixel level to correct poorly performing panels and safeguard manufacturing...
Curve Radii RepeatabilityThis paper quantifies Lattice Materials’ measurement methodology and manufacturing repeatability of a small diameter spherically generated silicon blank.
Multilayer Coating for Extreme Ultraviolet ExperimentsExtreme ultraviolet (EUV) multilayer coatings have been designed and fabricated for many kinds of experiments including high-order harmonics application. In this paper, we present recent results obtained with Ru/B4C, Mo/Si, Zr/Al-Si, SiC/Mg...

Our customers work in areas such...
Recent Research Using Meadowlark Optics Spatial Light ModulatorsThis ever-evolving collection of recent research using Meadowlark Optics Spatial Light Modulators offers a brief overview of specific applications in which Meadowlark Optics’ Spatial Light Modulators are most commonly used. Citations to published...
High-Quality Molded Glass for Various ApplicationsThe IHU series glass can transmit Ultra-Violet (UV) through the visible range.
Health and Sanitization through UV LightingWith increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it. Determining the amount of UV energy the light source emits onto the...
Dispelling the Myths About Laminated FiltersThere is a common belief that there is no longer a need for traditional bandpass optical filters. While this may be true in some cases, not all laminated filters are created equal. In this paper we will illustrate the advantages and disadvantages of...
UV Bandpass Filters for SterilizationUV light at 222 nm is capable of sterilization without harming human skin, making it a safe and effective technology to combat bacteria and viruses, including COVID-19. Optical filters can be designed to transmit the desired UV frequency while...
Wavelength Selection SolutionsEstablished in 1965, Optometrics is a leading supplier of standard and custom optical components and pre-aligned sub-assemblies for wavelength selection. The company’s core technologies include mechanical ruling, holographic recording,...
Optical Thin Films on Complex Substrate Geometries Enabled by Enhanced Deposition TechnologyThis whitepaper explains DSI’s low-pressure chemical vapor deposition (LPCVD) called IsoDyn, which specifically addresses the production of thin films on highly curved optics. These can be difficult or impossible to manufacture using other methods....
Pushing Freeform Optical Manufacturing: Fabricating Optimax’s Largest Freeform ComponentWhile manufacturing the largest extreme freeform optic that Optimax has fabricated to date, several issues associated with the size and complex shape of the optic were encountered, including generation and polishing of the part, logistics of moving...
Hexapod Advancements: Alignment and Industrial Control Applications1) Hexapod parallel kinematics together with novel controllers and algorithms allow for faster coupling optimization between (fiber) optical devices, across multiple channels. Many industries can achieve significant process savings, including...
Hybrid Gain Flattening Filters in Optical Fiber AmplifiersIridian Spectral Technologies has developed what is referred to as a Hybrid GFF, which combines the functionality of both a WDM and the GFF on one component. Specifically, a Hybrid GFF can block the pump laser from light in the range of...
Laser Marking and Coding Made EasyIn the packaging industry, new marks, codes and packaging material requirements are driving manufacturers to seek marking and coding solutions with flexible and adaptable performance. This guide features a complete marking and coding solution for...
What Are The Main Applications Of Optical Coating?We provide you with a detailed analysis and introduction to the application of Optical Coating in your daily life.
Making Color Images – How Bayer Filters WorkBayer filters are the most popular type of color filter array used by camera manufacturers to produce color images. This paper will describe how we perceive color, how a Bayer filter utilizes this information to detect colors, the common artifacts...
Colored Glass as a Versatile and Economical Means for Optical FilteringColored glass filters find many uses in optical systems including imaging, laser, and industrial equipment. We describe design and fabrication techniques for implementing low cost optical filters which are an excellent choice for production systems....
Advantages of VPH GratingsTransmission gratings open up many design options for the optical designer. In this tech note, we consider one special type: volume phase holographic (VPH) gratings. With benefits ranging from superior optical performance and design flexibility to...
