## Summary

RealSense has introduced Min-Z, an improved close-range depth feature in Perception Studio that extends usable stereo depth to about 2 cm on D401/D405 and about 12 cm on D43x/D45x without changing cameras.

## Why it matters

The original explains how Min-Z extends the near-field usable range of stereo depth and the trade-offs between two deployment paths, which can be used to evaluate grasping and close-range perception solutions.
