I'm not sure about certification but there is a lot of overhead in designing, producing, selling and servicing products. This is basically a prototype. It will probably work for a while but will be difficult to maintain if something goes wrong and the software won't be very polished. There are a lot of non-BOM costs that go into selling a commercial spectrometer. This is great if you want to DIY one but even a single sensor based visible light spectrometer with cheap parts can't be bought for close to the sum of its parts.
