Knowledge Q&A
Over 30 years experience of making magnifiers and fresnel lenses, we also have some useful knowledge to share with the public.
It's our pleasure to help people find a suitable magnifier so that their vision will be clear and bright.
In order to make the VR headset lens thinner and lighter, some lenses use Fresnel lenses. This lens has the same curvature as a normal lens, but has threads of different sizes on one side. But using a Fresnel...
Read moreApplication of Fresnel lens in projection system. Fresnel lens proved to be the best use in the projection system, its role is to collimate light and focus light. The Fresnel lens tunes the light source...
Read moreThe Fresnel lens is a sheet, round or other shape that is injected or molded from polyolefin materials. There are two main functions of the Fresnel lens acting on the probe: one is focusing, which is to refract...
Read morePositive Fresnel lens: The light enters from one side, and exits through the lens on the other side to focus into a point or exit as parallel light. The focus is on the other side of the light and is finitely...
Read moreIf the LED lamp lens element is made of optical glass, the production cost is relatively high and it is fragile. If the thickness of the element can be reduced, or even a sheet lens, the size of the optical...
Read moreThe infrared PIR Fresnel lens sensing method is static, and there is infrared light in the space. Because the dual-element probe adopts complementary technology, no electrical signal output will be generated....
Read moreThe design principle of the Fresnel lens is that the lens is no longer regarded as a whole during processing, but as an entity composed of many microstructures. These microstructures retain the curvature...
Read moreInfrared sensing systems can be divided into five categories according to their functions. They are measurement systems that use infrared as the medium. According to the detection mechanism, they can be divided...
Read moreThe first reaction to seeing the "Fresnel lens" is that I don't know what it is! Only after seeing the practical application of these Fresnel lenses, we know that it has already entered our daily lives....
Read moreTraditional lenses are relatively thick and heavy and small in size; Fresnel lenses are light, thin and large in size.
Read moreFrensnel lens for LED light distribution Fresnel lens can be moulded or injection mold depending on light source model, COB light source (value of luminous), light angle, distance from lamp bead to lens...
Read moreThe PVC Fresnel mangifying sheet can be cleaned by glass cleaning spray like Windex or lens cleaner spray. With clean water then wiped by a soft cloth or eyeglasses cloth and dray naturely.
