Introduction When infrared radiation propagates through the Earth’s atmosphere, it is influenced by various substances within the atmosphere, resulting in a decrease in the ability of light to penetrate. This phenomenon is known as atmospheric attenuation or atmospheric extinction. The impact of atmospheric extinction on infrared radiation is wavelength-dependent, showing distinct selectivity across different wavelengths. […]

What is MTF? Modulation Transfer Function (MTF) is a fundamental concept in optics and image quality assessment that quantifies how well a lens system is able to reproduce various spatial frequencies in an image. It establishes the correlation between the output and input within an optical system and stands as the most comprehensive method for […]
How Do Microscope Lenses Work? Microscope lenses are pieces of glass that work in a microscope to aid magnification. Based on the lens type and power, you can magnify a specimen by up to 1000x or more. How these tools work is straightforward, and this article will cover everything you need to know about them. […]
Microscopy systems find applications in diverse fields of scientific research, industry, and laboratory work. At the heart of these systems lie the objective lenses, composed of multiple lens elements and positioned closest to the specimen. Choosing the right microscope objective is crucial, as it directly impacts the quality of the images produced while keeping the […]
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 […]
An optical coating is a vital technique with many applications, including creating glasses for those with light-sensitive eyes and improving camera lenses. This article will cover all you need to know about optical coatings, such as what it is, how it works, and various types and technology. What Is Optical Coating? What is the optical […]
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 […]
