Learn How ZEISS Does Rigorous Testing of Scopes
You know that Zeiss riflescopes boast superb glass, excellent controls, and a rock-solid warranty. What you may not realize is how rugged Zeiss scopes are. Zeiss optics are designed for the toughest conditions that hunters may experience. Zeiss understands that hunting optics can be exposed to extreme temperatures, moisture, shock, and vibration.
To ensure Zeiss scopes perform in the toughest conditions, Zeiss tests production-line optics with rigorous testing procedures unrivaled in the optics industry. Zeiss runs Impact Shock Tests with 800 impact cycles at high G-forces. In addition, Zeiss does a continuous vibration test for 1.5 hours. Scopes are also tested in a salt spray environment to confirm corrosion resistance. But there is more — test optics are immersed in water for two HOURS at depth and the scopes are also lab-tested at -40° F in a climate chamber and also subjected to “temperature shocks” from -13° to +122° F. Now that’s some serious testing.
Zeiss does all this elaborate scope testing to ensure its optics perform in all situations, in all environments. View all these tests in this Zeiss video. We think you’ll be VERY impressed:
Impact Shock Test — 800 Cycles

Continuous Vibration Test — 1.5 hours


Water Immersion Test — Validated Waterproof for 2 hours at 13 feet

Temperature Testing — Extreme Temp Shock Test and Sub-Zero Freeze Chamber


Corrosion Resistance Test — 24 Hours in Salt Spray Environment














Mike Jensen, President of Carl Zeiss Sports Optics USA explains how the system works:
straight or angled bodies both boasting a rubber-armored exterior for protection. Eyepieces are available as variable 20-60x, 20-75x, or fixed 40x. A 65mm version of the new Diascope is also available, but we feel that, if you’re going to spend this kind of money ($3000.00 for 85mm with 20-60X eyepiece), you should go with the 85mm. The 20-75X eyepiece only delivers 15-56X when used with the smaller 65mm Diascope.
