I'd like to organize a group AR coating run ASAP. I've previously posted some details and have received significant interest. Having recently been extremely busy at work, I've had to ignore some PMs regarding the AR run, but with a more favorable work schedule on the horizon, I'd like to get the ball rolling....
This coating lab is excellent. The owner is very willing to meet our needs and has a business model very well suited to our (relatively) low volume. He has already sent me samples, which I have posted on RWG. He has been very responsive and motivated, and is quoting me 1 week turn times (excluding transit times). Here are the details:
The Coating
- Optically clear with slight Blue/Purple hue
- Approx. 1% reflectance of visible light on the coated side
- Durability: This will be a DURABLE AR COATING. Let's put this in perspective: Our coating will meet military spec Mil-C-675 for durability. As such, it can be handled with bare hands and very easily cleaned, if required. However.... it WILL NOT withstand the "screwdriver test" as uncoated sapphire will. So... it is durable, but it can and will scratch if you're not careful!!!
- Single sided OR Double sided coating is available. There will be no price difference, but before deciding to go with a double side coating please refer to gen forums and RWG posts where people are actually removing the outer AR coating on their watches for various reasons!!!
The Pricing
I think the pricing has improved since my initial post. They are very eager to work with us!! Here is the price schedule:
- 25 crystals = $45 USD per crystal
- 40 crystals = $30 USD per crystal
- 50 crystals = $25 USD per crystal
Prices include return shipping without insurance inside the CONUS. Insurance, international shipping (outside CONUS), etc will cost extra.
How this will work
Please post your intent to commit here. If you have any uncertainty about honoring your commitment, then do not post. If/when we have enough of a commitment to begin a run (40 crystals is a nice sweet spot), then I will provide an address (my address) to everyone participating. I will provide shipping instructions and you will ship your crystals to me. I will not be removing crystals from watches for anyone. I will package the crystals, label them, and then send them to the coating house as a single lot. The coating house will return them to me, and I will then ship them back to their owners.
Payment: At this time I would like to avoid paypal. The easiest thing (for me) is probably going to be a bank check (either money order or cashier's check) that is mailed to me along with the crystals.
So, that's about it... Hopefully the interest in this is still out there! Questions/comments, let me know.
