Bigger head, same optical upgrade. The NES-1140 takes the front-surface reflective technology used across this line and puts it on the widest available mirror size — 24mm — a combination aimed at clinicians who want both broad coverage and the sharper, single-reflection image front-surface coatings are known for.
Here’s the short version of why front-surface matters: standard mirrors place the reflective coating behind a layer of glass, which can create a faint ghosting effect as light bounces through the glass twice. Front-surface mirrors put the coating right on top, so what you see is a cleaner, truer reflection with no double-image to second-guess.
Where the extra size of this diagnostic instrument pays off:
Full-arch scans without repositioning between quadrants
Photography and documentation work needing consistent framing
Teaching settings where a larger reflected view helps students follow along
General practices wanting one versatile mirror for most situations
Surgical-grade stainless steel body, plain-stem design compatible with standard handles, and fully autoclavable. Because the reflective coating sits exposed on the surface rather than behind protective glass, gentle non-abrasive cleaning helps it hold its clarity over time. At $1.00, it’s priced identically to entry-level mirrors despite the sharper optics — a straightforward upgrade for practices ready to make the switch.
