Synthetic Ocular Diagnostic Close-Up

An extreme close-up macro photographic shot of an android's synthetic eyeball undergoing clinical diagnostic calibration, showing intricate microscopic mechanical gears, iris apertures made of polished obsidian metal, and glowing amber micro-circuitry pulsing gently behind translucent polymer sclera, delicate reflective glass lenses catching the beam of a medical scanning laser, tiny laser-engraved serial numbers etched subtly along the outer ring of the iris, setting taking place inside a sterile high-tech laboratory with soft white backlighting and surgical steel reflections, lighting consists of a pinpoint sharp laser line in vivid electric cyan cutting across the iris balanced by soft white diffuse illumination from a ring light reflection in the lens, micro-expressions revealed through the minute twitching of tiny servo-motors around the eyelid margin with synthetic skin showing realistic pores and micro-texture, tight macro framing focusing intensely on the iris mechanism with extreme depth of field falloff blurring the surrounding facial contours, shot on a 100mm macro f/2.8 lens with pristine clarity, high contrast, clean noise-free sensor render, hyper-detailed 8k resolution, cinematic sci-fi minimalism.
