Difficulties and Benefits of Optical System Design & Manufacturing

At Avantier, we use Zemax for designing, analyzing, and optimizing optical systems, such as lenses, objectives, cameras, and other optical devices.  For optical system design, Zemax helps to construct a virtual optical system by defining optical specifications, such as surface curvatures, thickness, refractive indices, etc. For ray tracing, Zemax simulates the propagation of light rays […]

How to Read an Optical Drawing

An optical drawing is a detailed plan that allows us to manufacture optical components according to a design and given specifications. When optical designers and engineers come up with a design, they condense it in an optical drawing that can be understood by manufacturers anywhere.  ISO 10110 is the most popular standard for optical drawing. […]

Lossless Image Compression Example

For storage and transmission of large image files it is desirable to reduce the file size. For consumer-grade images this is achieved by lossy image compression when image details not very noticeable to humans are discarded. However, for scientific images discarding any image details may not be acceptable. Still, all the images, except completely random […]

3D Image Analysis

Image Analysis of a 3D Image Several manufacturers sell 3D cameras which use 2D sensor arrays sensitive to the phase of reflected laser light. All of them spread laser light so that it permanently illuminates the complete scene of interest. Laser light is modulated synchronously with the pixel sensitivity. The phase of reflected laser light, […]
