"Carl, I've owned and used one of your magical creations for about 10 years, now. I am a true believer in buying reputation, and your reputation is very well deserved. The contrast produced by this mirror is just insane. After 10 years, it still feels like the first time, every time I use it."

October 21 2023 update

Our lead time has shortened over the last two years, due to orders slowing down. This is actually a welcome thing for us, as we had too many on the books, with a peak somewhere around 60 orders for mirrors. Currently we're down to about 36. This is preferable for everyone, especially for us at ZOC. We would like to have it shorten even more, and the trend is currently in that direction.

We can probably now officially shorten the lead time to 12 months with the outset being 18, depending on the mirror. We do have some 22's to process, which we no longer sell. Those will take a few months by themselves. But generally 12 months for small mirrors would be about right in this timeframe.

A 50% deposit places an order and begins the lead time. When the mirror is completed and goes to our lab for coating, the balance is due. Contact us for more details and payment options.

Shipping costs- We ship at the lowest possible rates, at actual cost to us for both foreign and domestic shipping. We now use both the US Postal Service and Federal Express for international shipment. FedEx is used exclusively for domestic shipment. We really like the FedEx service for both domestic and international. In most all sizes Zambuto Optical buys the insurance risk for the shipment. This policy has saved our customers a lot of money, and so far it's gone well. So there are no added insurance fees to ship internationally, unless our customer requests it.
