We are Moving!

Imatest is relocating to new office space in January 2021. We will minimize the impact to our customers, but we do anticipate longer lead times for order fulfillment. Our standard lead times will be suspended through the end of the February 2021 and will resume in March 2021. We will make every attempt to minimize the production downtime, but we cannot guarantee shipment of any new orders before this time. Our standard chart lead times can be found here: Shipping Policy.

Our new address will be 2525 Frontier Ave, Suite B, Boulder, CO 80301

  • 95% uniformity on Size B and 93 % uniformity on Size C.
