An aspheric lens may have any of a number of geometries. Most of them are rotationally symmetric but have a more complex front surface. Unlike a spherical lens, the curvature changes with the distance from the optical axis. Another way of putting this would be to say that the radius of curvature varies radially from the center of the lens.

Aspheric lenses are optical lenses with non-spherical surfaces (aspherical surfaces), meaning they have a changing curvature across the lens rather than a constant curvature, as seen in spherical lenses.  Because they contain controlled variations in curvature across the surface of the lens, they correct for the optical aberrations that occur with spherical lenses. Removing these aberrations has several important benefits:

Response time, on the other hand, is the time it takes for a pixel to shift between colors. The more responsive your monitor is, the shorter the response time it’ll have.

You may also want to check if your monitor cable is intact. A damaged monitor cable could result in monitor ghosting, in which case you should change your monitor cable and test if the problem persists.

Monitor ghosting or screen ghosting, as the name indicates, is a monitor/display issue. It has little to do with your system. Monitor ghosting usually occurs when there are multiple images moving fast on your screen, or when you’re moving your mouse quickly. If your monitor is ghosting on your game, you’ll likely notice:

Our lenses are available with anti-reflection coatings or in uncoated forms, in glass, crystalline, or plastic substrates. State of the art grinding and polishing metrology equipment, including computer-controlled precision polishing devices and magneto-rheological finishing (MRF) technology, enable us to ensure that the surface quality is optimized for your application. MRF technology enables high-performance finishing results in significantly less time compared to conventional polishing methods due to its precise control of the removal location and rapid removal rate.

By integrating controlled variations in curvature, optical engineers can utilize aspheric lenses to improve systems’ image qualities, create more compact and lightweight designs, and increase design flexibility.

Simply put, screen refresh rate refers to how often your screen displays a new image. For example, a 60Hz refresh rate means that the monitor refreshes itself 60 times per second.

Sometimes other devices connected to your PC, such as your keyboard or speaker could interfere with your monitor’s function. It could be an issue of proximity, meaning that you just need to keep your monitor far from those devices.

One way to keep your video card driver up-to-date is to manually update it via Device Manager. If Windows suggests your driver is up-to-date, you can still check if there’s a newer version and update it in Device Manager. Go to the manufacturer’s website, and search for the latest correct driver. Be sure to only choose a driver that is compatible with your Windows version.

the branch of optics that compensates for image distortions, especially by means of flexible mirrors or membranes.

To test if your monitor has the ghosting issue, you can find several tests online. The most popular tool is UFO Test. You’ll get a green signal saying READY if your monitor doesn’t have a ghosting issue. Otherwise, you may get an orange signal suggesting a specific problem with your monitor.

If your monitor supports variable refresh rates, you can set it to a higher value to tackle the monitor ghosting problem. To view the refresh rate of your monitor and make adjustments if possible:

An aspheric lens is an optical lens with a non spherical surface profile; its surfaces are not portions of a sphere or cylinder. There are many types of custom aspheric lenses with various geometries. Unlike spheric lenses, they do not have a constant radius of curvature. They are designed to eliminate almost all spherical aberration, and by light focused to a small single point they drastically decrease the amount of blur and so improve image quality. Using aspheric lenses typically results in more compact assemblies as there are fewer aberrations to be corrected for. As an aspheric lens manufacturer, Avantier manufactures a wide variety of custom aspheric lenses solutions for applications from smartphones to lasers and fiber optics, from research and industry to medicine.

Typically, the further from the optic axis, the weaker the curvature. A lens that does not have these symmetries is typically called a free-form optic.Aspheric lenses are defined by their surface profile (sag of the surface parallel to the optical axis) or by means of orthogonal coefficients Qbfs and Qcon. Qbfs quantifies the RMS slope departure of your aspheric lens from a best fit sphere,  and Qcon  quantifies the sag departure from a base conic.

Custom Aspheric Lenses have important applications in high precision imaging. From aerospace night vision imaging optics to defense imaging, from microscope imaging objectives to semiconductor wafer inspection tools, they are essential components of many precision imaging devices. For instance, the Smite Cassegrain telescope uses them as well as reflective elements to reduce aberrations and create a high-resolution image. Optics manufacturers often prefer these solutions for their ability to deliver superior performance in demanding environments.

Monitor Ghosting is a common issue that you might see on any monitor. If you’re playing a shooter or an action game, you’re likely to encounter this issue which can ruin the whole gaming experience. It could also occur when you’re editing videos or working on tasks that involve displaying fast-paced scenes.

First, you want to make sure that your monitor cable is firmly plugged in. Try unplugging then replugging in the cable and test if the issue persists.

Although we explained earlier that screen ghosting is primarily an issue of the monitor, not of GPU, you could still try updating your graphics driver. When you can’t identify what’s causing your monitor to ghost, it’s a good idea to do so since it generally fixes and prevents many display issues, which may include monitor ghosting in your case.

In addition to response time and refresh rate, you could experiment with other display settings to see if it helps solve the monitor ghosting issue. Make sure to test your monitor’s functionality while adjusting. To make additional tweaks, look for these settings:

The focal length of a lens is the optical distance (usually measured in mm) from the point where the light meets inside the lens to the camera's sensor.

As we mentioned above, refresh rate and response time are the main factors that are responsible for the ghosting issue. You can adjust your monitor’s settings to achieve a higher refresh rate and a lower response time which helps prevent your screen from ghosting.

You may now wonder, why is your monitor ghosting? Ghosting is most frequently seen in LCD monitors, but for any type of monitor, the two main factors remain the same: refresh rate and response time.

The good news is, it’s easy to identify if your monitor has this issue. Plus there are some known effective fixes. In this article, we’ll explain what monitor ghosting is, why it happens and most importantly, we’ll cover how to fix it. Read on for more information…

If the video port of your monitor is faulty, it could probably cause you screen to ghost. We recommend taking your monitor to a local repair store since it’s very difficult to identify the problematic component and replace it. If your monitor is still under warranty, you may also contact the manufacturer for support.

Or, you could disconnect those devices one at a time and test if your screen still ghosts. Make sure to check the wireless devices as well. If one of your devices seems to cause the ghosting issue, try not to use it with your monitor at the same time.
