At present, our company has multiple single-point diamond lathes with an open design and can produce giant Fresnel lenses with a diameter of less than 2200mm. The mold quality and processing level are at the forefront of the world. Yuying can design Fresnel lenses of different specifications according to the customer’s light concentration ratio and the size of the solar panel to achieve the desired light concentration effect. Can be used in solar power stations, outdoor sunshades, kitchen utensils, etc.

This precious and quickly obtained information allows to define precisely the area in need of an intervention. Therefore, the resources are used where they are needed and this management guarantee successful collection with cost-efficient surgical operations.

Shandong Yuying was founded in 1992, we have many years experience in the field of FRESNEL LENS. Our R&D engineering team is here to make your ideas realized. ODM & OEM are both welcomed.

Thanks to a UAV equipped with an hyperspectral camera, this troubling factors can be spot early while already occurring but not being visible yet with the naked eye. The camera covers the entire field by scanning it. The disturbed areas will reflect certain wavelengths while the rest of the field won’t.

Hyperspectralcamera

This can be done with multispectral and hyperspectral sensors.Visible (red, green and blue), infrared and ultraviolet are descriptive regions in the electromagnetic spectrum. We made up these regions for our own purpose – to conveniently classify them. Each region is categorized based on its frequency (v) /wavelength (?):

Multispectralimage

Human eyes see the reflected energy from objects in three channels: red, green and blue. We don’t have the luxury of seeing ultraviolet and infrared radiations on our own.

There are hundreds more applications in the fields of agriculture, ecology, oil and gas, oceanography and atmospheric studies where multispectral and hyperspectral remote sensing are being used to better understand the world we live in.

Difference betweenmultispectralandhyperspectralremote sensing

1. Multispectral imagery generally refers to 3 to 10 bands that are represented in pixels. Each band is acquired using a remote sensing radiometer.

Shandong Yuying provides the large size solar concentrated Fresnel lens ,including CPV lens which is made of SOG,Linear lens and Fresnel lens.

Multispectral vs HyperspectralHaving a higher level of spectral detail in hyperspectral images gives better capability to see the unseen. For example, hyperspectral remote sensing can distiguish between 3 minerals because of its high spectral resolution.

This vital sector is always pleased to integrate new solutions built to improve the efficiency and results of collections. Being exposed to numerous stress factors, it is necessary to spot as soon as possible a lack of water or nutriments and the presence of parasites or other wild animals for example.

2. Hyperspectral imagery consists of much narrower bands (10-20 nm). A hyperspectral image could have hundreds of thousands of bands. This uses an imaging spectrometer.
