# Industrial Specification: Precision Optical Lens Centering Machine

## 1. Technical Definition
Industrial machine for aligning optical lens optical axis with mechanical axis.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-5.0 μm radial alignment tolerance, 0.01-0.5 μm axial runout**. Failure boundary: **Radial misalignment &gt;5.0 μm or axial runout &gt;0.5 μm causes optical aberrations exceeding λ/4 wavefront error at 632.8 nm wavelength**, Mechanism: **Rayleigh criterion violation: wavefront distortion from mechanical misalignment exceeds λ/4 limit, causing destructive interference and MTF degradation below 0.3 at 50 lp/mm**.

### 2.1 Analytical Physics Model
Governed by the **Rayleigh Resolution Criterion**:

> **Primary Equation**: $d = \frac{0.61 \lambda}{NA}$
