High Reflective Coatings Optical coatings are thin films that are applied to optical components to control their reflectance, transmittance, or polarization properties. They are used in a wide variety of applications, including lasers, telescopes, cameras, and medical devices. How Optical Coatings Work Optical coatings work by interfering with the light waves that are reflected or […]
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. […]
Anti-Reflective (AR) Coatings and Metal Film Coatings for Mirrors The article has already covered various types of coatings. In this particular piece, our focus will shift towards delving into the specifics of AR coatings and metal film coatings, particularly in the context of mirrors. In this article, we will delve into Metallic Mirror Coatings: The process […]
Spherical mirrors come in two types: concave and convex. While they have better light collection capabilities compared to planar mirrors, they suffer from astigmatism. This phenomenon results in light emitted from a point source not converging to a single point due to a shift in focal length. On the other hand, parabolic mirrors are a […]
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” […]
