Yes, so two separate things, right. The Navy -- the licensing of the Navy materials as I mentioned, they really one thing we've seen from the discussions I've had in Washington and with different government officials and such, is that we are really at a perfect timing from that since, the U.S. through the Defense Production Act and through the executive order of the Biden administration on resilient supply chain is heavily investing in developing a manufacturing base in the U.S. and accelerating readiness of new technologies, increasing local capacity and such. So, the U.S. currently imports, as I mentioned 90% of its germanium, that is $2.7 billion roughly of germanium a year, quarter of that goes into optics around $600 million, $700 million of germanium goes into optics in the U.S. Chalcogenide is, I think perfect spot to substitute that. Now, we cannot -- it’s not a one-to-one substitution and you will not completely eliminate germanium. But we are definitely the best option at this point for the U.S. in terms of reducing the dependence on China and Russia for that material. So, I think accelerating that is a key element of many stakeholders, including some of our time customers, who are seeking to be involved in helping us accelerate that and bring those materials to market. We are anticipating that in the next few months, the first material might be already released. We're currently already working on copper pipes and we're working with some of the primes, also on designing the material in seeing the encouraging results that we have. But it's really a key element here, I think in much of what the U.S. is looking at. In terms of the free form optics, that's a bit of a different play in the sense that this is a technology that we've already developed and matured enough now is the time for the customers to take that in and to utilize it, we've mentioned in the last months that Attollo Engineering, for example, have already adopted free form optics into their LIDAR products and it looks very promising and successful, they have some very unique products in the sense of being able to very quickly monitor the location of drones of fully autonomous drones making sure they don't collide with other and so on and the free form optics are really a key elements there. In other places, we've shipped prototypes already to AL countries, for example, have already -- our free form optics in prototypes, others are at different stages of it, LIDAR is becoming a bigger piece there, but that will take longer, because most of those -- the free form optics is enabling a cutting-edge application to such a degree that set application needs to first be adopted and when its owned commercial success, before the free form can scale up with. And it looks very encouraging.
