VL53L0X X-NUCLEO-53L0A1盖玻片材料是什么

Hy Sciro，
你从未听过ST关于你的问题，对吗？显然，这个william hill官网 没有得到很好的维护。无论如何。
我不知道，他们在X-NUCLEO上使用的是什么样的玻璃。我制作了一些使用''Acrylglas /Plexiglas®XTklar，1.5mm'的设备。我不知道材料的确切定义，这是我从经销商处购买的产品的名称。
我从ebay得到的很便宜：

我用玻璃做了一些测量。我发现传感器表面必须紧紧地压在玻璃上。只要我有一个小间隙或传感器表面和玻璃之间有微小的倾斜，就会有更高的噪音，更少的信号和绝对误差。黑白漂移和环境光影响也增加。所以我所做的是将传感器尽可能好地安装到玻璃上，然后用硅胶粘合（我使用卫星板）。
也许这有帮助。问候
哈拉尔

VL53L0X X-NUCLEO-53L0A1盖玻片
 
我们正在使用VL53L0X IR飞行时间传感器开发产品。传感器必须位于塑料外壳内，透过IR透射窗口材料。为了测试这样的布置，X-NUCLEO-53L0A1配有气隙垫片和覆盖玻璃材料。我想知道这种玻璃材料是什么，你能给出制造商名称，产品/产品名称或其他什么吗？



以下为原文





Hy Sciro,
you never heard back from ST about your question, right? Apparently, this forum is not well maintained from them. Anyway.
I do not know, what kind of glass they use on the X-NUCLEO. I built a couple of devices that use a ''Acrylglas/Plexiglas® XT klar, 1.5mm'' I do not know the exact definition of the material, this is the name of the product I bought from my distributor.
I got if from ebay quite cheap:

I made some measurements with the glass. I find out, that the sensor surface must really be pressed to the glass tightly. As soon as I have a small gap or there is a tiny tilt between sensor surface and glass there is higher noise, less signal and an absolute error. Also the black-white drift and the ambient light influence increase. So what I do is mount the sensor as good as possible to the glass and then  glue it with silicone (I use the satelite board).
Maybe that helps. Regards
Harald

VL53L0X X-NUCLEO-53L0A1 Cover Glass

We are developing a product using the VL53L0X IR Time-Of-Flight sensor. The sensor must be inside a plastic case looking through a IR transmissible window material. To test such an arrangement the X-NUCLEO-53L0A1 comes with airgap spacers and cover glass materials. I would like to know what this cover glass material is, can you give a manufacturer name, article/product name or something?

我很确定ST不推荐玻璃，因为有太多的选择，他们无法完全测试。
下图显示了一些选择。 PMMA是标准丙烯酸。它便宜且可用。但它有划痕，通常可以看到它，所以它可能不适合您的应用程序。不幸的是没有厚度测量。我很确定更薄更好。我发现ST'玻璃'的一个问题是它非常脆弱。

I'm fairly sure ST doesn't recommend glass because there are way too many choices and they can't test them fully.
The following chart shows some choices. PMMA is standard acrylic. It's cheap and available. But it scratches and generally one can see through it, so it might not be good for your application. Unfortunately there is no thickness measurement. I'm pretty sure thinner is better. One issue I have found with the ST 'glass' is that it is pretty fragile.

刚刚找到ST应用笔记 - 编号AN 4907

这描述了一个好的封面玻璃。但它也提供了一个参考，你可以买到玻璃。虽然没有给出价格。
也许值得一瞧。

This describes what a good coverglass is. But it also gives a reference where you can buy the glass. Doesn't give a price though.
Might be worth a look.
