The resolution is 0.25mm and camera is 5.0 megapixels, which is base on the distance between camera and object. In this data I think it only can scan something bigger then 1mm if less then 1mm cannot get very detail. Or you can ask they to get the scanned images files and do 3D meshing by yourself, OR You can buy it first, after that if you think is not enough resolution then change the camera and laser.
the logic is very easy,
1) use laser to create the basic model shape,
2) then use the image to create the object texture which need around 360 images,
3) use the basic model shape + CV program to find out more detail.
In the raspberry pi you can very easy change to use USB Camera to higher resolution.
