probably the most advanced X-ray detectors in the world, both for dental and medical applications. That business is growing fast enough, that we've had to increase our capacity in our Eindhoven laboratories, so that we can have a two X-ray detector production facilities, one in Waterloo, and one in Eindhoven. Second, demands, as I mentioned, micro electromechanical relays, micro electrical -- mechanical systems, there we have increased -- we have to increase, again, capacity. You saw, our CapEx is increased a little bit, that's partly, again, we're having to increase capacity by 9,000 square feet with clean rooms, in order to accommodate increased demand from both life science. We make some very interesting products for life science applications, as well as for more semiconductor applications as well as machine vision applications. So having said all of that, I think, the distribution of growth is a across our products. It ranges from MEMS to new products, in sensors, new products in machine vision, and also increased revenue from our RF products that are going into radiotherapy for cancer patients. So, it's a broad portfolio, and it's seems to be hitting on all cylinders so far.
That's great. And a question for Sue is, is $80 million for CapEx a reasonable estimate for this year?
Susan L. Main
Yes. We're thinking between $80 million, $90 million.
Great. Thank you very much for taking my questions.
At this time, we actually have no further questions in queue.
Thank you very much, Justin. I now ask Jason VanWees to conclude our conference call.
Thanks Robert, and thanks everyone for joining us this morning. If you do have a follow-up questions, please feel free to call me at the number on the earnings release. Justin, if you could conclude the call and provide to replay information, we would appreciate it. Thanks again.
