Fig. 3
Ø20mm
Same 20mm plain mirror head as the standard Fig. 3 design, but built with a cone-socket fitting instead of a straight stem. That threading style lets the mirror head screw securely into cone-socket handles, giving a firmer, wobble-free connection than friction-fit alternatives — something clinicians notice during longer procedures where a loose head becomes an annoyance rather than a convenience.
This diagnostic instrument itself is unremarkable in the best way: flat, distortion-free, and made from surgical stainless steel that shrugs off repeated sterilization. What sets the NES-1123 apart is purely the socket mechanism, which appeals to practices standardized on cone-socket handle systems rather than the more common plain-stem type.
A quick comparison for context: it shares its 20mm head size with the plain-stem NES-1119, so if your practice already likes that mirror’s field of view but needs the cone-socket fit for your existing handles, this is the direct equivalent.
At $1.20 — a modest premium over the plain-stem version — it reflects the slightly more involved manufacturing of the threaded socket. Suited for general dentistry, hygiene checks, and restorative work where a secure mirror-to-handle connection is non-negotiable.
