• High-precision 38.1 mm SMR sphere – Optimized for laser tracker systems requiring 1.5″ retroreflectors with standard 25.4 mm offset.
• Corner-cube prism with multi-layer coating – K9 optical glass ensures excellent signal return and minimal beam deviation (≤ 5 arcseconds).
• Exceptional rotational accuracy – Built to achieve ≤ 0.0003″ deviation, ideal for high-end metrology applications.
• Hardened SUS-440C stainless steel housing – Delivers long-term durability, wear resistance, and structural stability under field and lab conditions.
• Available in drop-resistant versions – Ver 2.0 kits include reinforced structure and shock-absorbing ring for use in rugged environments.
• Multiple mounting options – Compatible with magnetic, shank, and edge holders for flex
• Protective finishing – Chrome-plated anti-corrosive surface resists oxidation and ensures long-term optical stability.
• Universal system compatibility – Works seamlessly with FARO, Leica, API, Hexagon, and most major laser tracker brands.
• Kit options tailored to your workflow – Choose between basic unit, standard kits, or Ver 2.0 drop-resistant configurations to match your specific needs.

Q1: Is this SMR compatible with my laser tracker (e.g., FARO, Leica, API)?

A: Yes, all SMR variants are designed with a standard 38.1 mm spherical form and 25.4 mm offset, making them fully compatible with leading laser tracker systems, including:

• FARO Vantage series
• Leica AT960 / AT403 / ATS600
• API Radian Pro / Plus
• Hexagon / Nikon systems

 If you use a custom mount, make sure to check the holder type (magnetic, shank, edge) for direct fit.

Q2: What’s the difference between drop-resistant and standard SMRs?

A:Drop-resistant SMRs (Ver 2.0) feature an enhanced mechanical design to withstand falls and vibrations during field use. Key differences include:

• Reinforced steel housing
• Shock-absorbing protective ring
• Secure removable ring with wrist strap (on some variants)
• Optimized for mobile or rugged environments

In contrast, standard SMRs are intended for lab or controlled environments, offering the same optical precision but without protective reinforcement. They’re lighter and more affordable, ideal for fixed setups or stationary use.

Q3: Can I upgrade from a basic SMR to a full kit later?

A: Absolutely. If you purchase the single-unit SMR, you can later buy compatible holders, nests, and storage cases separately. All mounting options are designed to fit standard 1.5" SMR designs with 25.4 mm offset.
