A UK forum question/discussion re lens coatings got me wondering...I'm not looking for any proprietary or secret info, just curious if a small custom-production shop like Astro-Physics coats their objectives in-house (themselves) or outsourced to a coating shop/specialist? I understand this process is very expensive for the equipment and to recoup the investment, but knowing how AP prefers the hands-on approach I was curious how they handle this part of the in-house manufacturing process along with overall lens production and CNC milling.
