What are some examples of light pollution? What is a semiconductor laser? What is a white light solar filter? What is cycloplegic refraction? What is light resistance training? What is the green flash at sunset?
Examples of stray light include: Light reflections off mechanical mounting surfaces inside the optical system Light leaking through a gap in the system enclosure Light scattering off dust and other imperfections on the system’s optical surfaces For ground-based astronomy, sky glow, caused by the...
Laser optics are as varied as the applications they service, ranging from fiber communications micro-optics through meter-class telescope mirrors. They manipulate laser beams through virtually every type of light/matter interaction, including refraction, reflection, diffraction, polarization, and spectrally ...
What are some examples of mechanical energy? What are the main concepts in wave optics? What would a good hypothesis be for a physics experiment, where I am testing to see how increasing weight that is dragging from the back would affect the speed of a cart that uses a fan on ...
Does light travel as a wave, a ray or a stream of particles? Is it a single color or many colors mixed together? Does it have a frequency like sound? And what are some of the common properties of light, such as absorption, reflection, refraction and diffraction? You might think ...
Spectroscopy and diffraction techniques can also be used to capture how the composition is structured. Measurements such as where various atoms sit in a crystal or how long polymers are crosslinked are needed to capture the bulk behavior of the material. Various types of microscopes can also be ...
Let's now take a look at a couple examples of this relationship... Energy-Mass Unification You should readily understand how a system with very little mass has the potential to release a phenomenal amount of energy (in E=mc², c² is an enormous number). In nuclear fission, an ...
Here are my first thoughts about estimating the reflectivity of microlenses. My Nikon Z6 has had all the internal filters removed, leaving only the sensor itself. Here is an image of an LED lamp causing the diffraction pattern: What we are seeing is a direct reflection of the LED lamp...
As you obviously suspected, the halos are a microlens diffraction pattern reflected off the Astrodon SII filter. The geometry indicates it is a filter 14mm from the sensor: ASI294MM_SII_Halos.jpg Mark I am wondering why this is happening on Ha and S11 and not O111. Is there some ...
Diffraction refers to the phenomena of slight bending of light as it encounters an obstacle or a slit or as it passes around the edge of an object. In diffraction, the amount by which light is bent depends on the relative size of the wavelength of the light to the opening of aperture. ...
