Documentation of the Product SKU_SEN0590

I need the following information for SKU_SEN0590:

1. Data sheet of the product

2. Measurement accuracy: ≤25cm@±1cm, >25cm@±S*4%cm, what is S here? S means standard deviation. If so, what is the standard deviation for this product?

3. What is the operating wavelength of laser?

It would help us as we are going to use this sensor in our product.
