What Is the Modulation Transfer Function (MTF)? Understanding and Utilizing the Modulation Transfer Function in Optical System Design The Modulation Transfer Function (MTF) is a vital parameter used to assess the performance of optical systems, ranging from simple lenses to complex imaging lens assemblies. It serves as a standardized quantitative measure for optical designers and […]
Spectrometer optics is a specialized field that involves measuring light intensity by using a spectrometer to separate light by wavelength. Spectrometers find applications in various fields, ranging from studying distant galaxies to analyzing proteins in biochemical research. Avantier Inc. boasts a skilled engineering team proficient in designing spectrometers for research, industrial, medical, and defense applications. […]
Optical surface accuracy refers to the difference between the actual shape and the desired shape of an optical surface. It is a crucial aspect of optical components and is typically measured in terms of fringes or waves that correspond to the laser wavelength used in the interferometer. And it is important to specify the expected […]
How Polarizing Beam Splitter Works There are several types of beam splitters for many various applications in the world today, but this short read will concern itself with polarizing beam splitters. Polarizing beam splitters, as their name implies, are a kind of beam splitter that divides a single beam of light into two beams of […]
The simple answer to what the main difference is between a mirror and a lens is that a mirror is something that reflects an image, while a lens is something to look through to see an image. Of course, we could go more technical than this and discuss mirror and lens physics through optics and […]
Optical Tolerances In real manufacturing, a certain amount of error will unpreventably occur between the measured value and the designed value. In terms of measurement, the difference between the maximum and minimum dimensions of permissible errors is called tolerance. If it is written on the drawing that “3.5 +0.05/-0.00“, “3.5” represents the reference dimension, “+0.05” […]
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 through the […]
Blurring is a significant source of image degradation in an imperfect imaging system. The optical system’s point spread function (PSF) describes the measure of blur in a given imaging system and is often used in image reconstruction or image recovery algorithms. Below in example of using inverse PSF to eliminate the barcode image degradation. Barcodes are […]
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. […]
