高強(qiáng)度紫外線燈XEPU-1605B在潔凈室檢測落塵

無塵室泛用的落塵監(jiān)控設(shè)備（Particle Counter）只能在單位空間檢測出環(huán)境落塵品質(zhì)（Class/1000/1000/100），不能了解Particle落塵何處，這將對制程良率有著一定的弊端，有些低照度的紫外線燈在無塵實(shí)驗(yàn)室檢測落塵的情況不理想，客戶用到我們析浦科學(xué)儀器高強(qiáng)度紫外線燈XEPU-1605B照射目標(biāo)物，輕易的找出目標(biāo)物Particle以及生產(chǎn)設(shè)備的落點(diǎn)處，進(jìn)行相關(guān)處理，提升產(chǎn)品合格率，解決無塵實(shí)驗(yàn)室落塵問題。

潔凈室Particle檢測原理是：

污染顆粒吸收照射的紫外線光能量，從而發(fā)生熒光反射效果。產(chǎn)品的紫外線強(qiáng)度越高，污染顆粒能夠吸收足夠多的紫外線能量，所產(chǎn)生的熒光反射效果越好，檢測效果越清晰，反之輕度越低，就越容易漏檢。對于無塵室，一些地方的污染顆粒本來就很少，如果便攜式紫外線燈的紫外線強(qiáng)度不夠高，達(dá)不到發(fā)生熒光反射所需要的能量，有些臟污就檢測不出來。開始使用XEPU-1605B高強(qiáng)度紫外燈檢查設(shè)備或環(huán)境的落塵狀況時，需要把車間的燈關(guān)掉，更好是在黑暗的環(huán)境下檢測，光線太強(qiáng)會對紫外線有干擾和影響，會影響測試效果。

紫外線燈XEPU-1605B在無塵實(shí)驗(yàn)室檢測落塵

如上所說無塵實(shí)驗(yàn)室檢驗(yàn)落塵，紫外線輕度越強(qiáng)，檢測效果越好。紫外線燈XEPU-1605B是XEPU-1605的增強(qiáng)版，使用多個光學(xué)透鏡，紫外線強(qiáng)度高達(dá)23000UW/cm2在15英寸距離（相當(dāng)于380mm距離 ）以上，同行業(yè)紫外線燈在相同條件下的強(qiáng)度只能達(dá)到10000uw/cm2左右。紫外線燈XEPU-1605B波長在365~370nm，由5×5W 365nm UV LED組成，LED平均壽命是30000小時，照射面積可達(dá)120 * 160mm（38厘米距離），使用可充電鋰電池，方便攜帶。目前很多無塵室都做在使用析浦科學(xué)儀器XEPU-1605B紫外線燈，如：比亞迪，斯坦雷電氣，捷普集團(tuán)等

XEPU-1605B Particle Visualization LED UV lamp

Particle Detection, Clean Room Inspection

Visual detection of very small fibre-, lint and fluff-particles every where small under daylight invisible items are not acceptable, like manufacturing of pharmaceutical products, medicines, high-end cables, optics, valves, contact areas.

• Visualization of fluorescent particles by UV light on all surfaces, e.g. plastic, stainless steel and aluminum as well as wipes or cleanroom clothing

• Allows the regular visual control of contamination in the cleanroom

• Cleaning operations can be directly optimized - without the use of a measuring device

Assembly cleanliness is of crucial importance for ensuring process and product quality. In VDA Volume 19 Part 2, which focuses on technical cleanliness in assembly, the cleanliness specification of a component, assembly or assembled system is the starting point for assembly cleanliness. The aim of all measures is to prevent particles from being introduced during assembly and the associated processes that should not be present in the component according to the cleanliness specification.

Since a wide range of cleanliness requirements can be derived from the "environment" influencing factor in particular, VDA 19.2 divides the spatial environment into different cleanliness areas with different cleanliness levels. In order to objectively evaluate the cleanliness of these areas and, if necessary, improve it with suitable measures, particles must be reliably detected and quantitatively evaluated. At XEPU Scientific, you can obtain professional measuring equipment for particle visualization and visualization of defects on smooth surfaces.

Special lamps for particle visualization

The particle visualization lamp XEPU-1605B was developed for particle visualization as part of the regular visual inspection of contaminants in the cleanroom. It emits UV light (365 nm wavelength) and thus makes fluorescent particles visible on all surfaces. Typical inspection areas include cleanroom surfaces made of stainless steel, plastic and aluminum, as well as cleanroom clothing and wiping cloths.

To protect the eyes, protective goggles should be worn during particle visualization under UV light, which are also included.

For the inspection of process chambers, machines, equipment and materials, XEPU Scientific offers a highly efficient inspection lamp. It is characterized by particularly bright light.
