The GVM ring light has a Bi-color setting, you can adjust the color temperature from 3200K-5600K freely without a color filter. It is a special LED SMD design, lightweight and portable.

A converging lens will focus light from a distant source to the point called the focal point. The focusing is illustrated in the figure on the right.

Resolution and magnification are not the same. In microscopy, we refer to the details visible in a magnified image as resolution. Magnification, or making something appear larger, doesn’t do you much good if you cannot see the detail in the sample you’ve magnified.

GVM ring light is widely applied to portrait, makeup, YouTube videos, studio shoot, video blogging, portrait photography and live streaming, etc.

Bright-field microscopy relies on the differences in absorption of light due to differences in densities between various parts of the sample, which for our purposes is a cell. Because of this, bright-field microscopy is not great when you want to see many details in your cell. How do you increase your resolution? Add in fluorophores to stain structures in your sample and filters to illuminate it, focus the light emitted by the sample, add a sensitive detector, and voila! Now you can do fluorescence microscopy. Fluorescence microscopy gives you the advantage of better resolution by making various structures in the cells contrast better with their neighbors, as well as allowing you to collect images in more than one color.

If you use additional lenses to increase your ability to magnify a sample, you’ve got a compound microscope. Most modern microscopes are compound microscopes, because the additional magnification gives a more enlarged image. If only white light is used for illumination, then it’s bright-field microscopy.

In contrast, when we talk about resolution in a practical sense, we are referring to how much detail we can distinguish in our image, which can be subjective. In a more technical sense, resolution is limited by the refractive properties of light.

Microscopes are powerful research and discovery tools and have contributed to countless ground-breaking discoveries, over several centuries.

20231213 — LightStanza, a cloud-based collaborative lighting calculation software, is incorporating artificial intelligence into its lighting design tools.

A microscope magnifies objects; more lenses translate to higher magnification. In its most basic form, a microscope is simply a device that allows you to see things that are not visible to the naked eye by the use of lenses to magnify your sample. That means a magnifying glass is technically also a microscope. If you use light along with a lens, you’ve got something called an optic or light microscope.

It’s pretty important to understand the difference between magnification and resolution when it comes to getting a good result when you’re doing fluorescence imaging. When we talk about magnification, we are referring to how much bigger an object appears when we look at it under the microscope.
