Inline Dimensional Measurement System | POMEAS HM Series
POMEAS inline dimensional measurement systems: HM telecentric measuring heads and the LM-1030 laser diameter gauge for non-contact production-line inspection.
Fiber Optic Component Hole Measurement: 10-Workpiece Repeatability Test | POMEAS
Real test data: POMEAS HM-series inline image measuring head on a fiber optic component with two micro-holes. 10 workpieces, 5 readings each, pooled σ 0.39–0.50 μm.
Optical Communications Precision Measurement Solutions | POMEAS
Inline image measuring heads, laser diameter gauges and 3D optical metrology for fiber optic connectors, ferrules, fiber arrays and optical transceiver components.
SiC Wafer Defect Inspection: Zoom Lens vs APO Objective With Laser Autofocus
A missed 1 µm SiC defect is a resolution problem, not a pixel one: at 7.5× a 12.5X zoom samples 0.46 µm/pixel but resolves 3.05 µm. Sampling math, BF/DF/PL modes.
Motorized Zoom Lens and PLC Integration | POMEAS
A PLC triggers and interlocks; the lens controller moves. The five-step handshake, the interlocks that prevent wrong-magnification frames, and what to confirm per model.
Industrial Zoom Lens for Laboratory Benches | POMEAS
A lab bench needs a zoom range matched to its sample set and a record that can be compared months later. Sizing, sampling, working distance and documentation habits.
Zoom Lens for Medical Device Inspection: Selection Rules | POMEAS
Four optical requirements decide the lens for medical components, plus the cleanroom and record constraints that eliminate otherwise suitable options.
Transparent and Coated Surfaces: Zoom Lens Setup | POMEAS
Transparent parts fail on contrast, not resolution. Two-surface ghosting, depth of field, and which illumination makes an edge visible at all.
Single-Motor vs Dual-Motor Zoom Lens: How to Choose | POMEAS
One motor drives magnification, two drive magnification and focus. What the second axis buys in changeover time, and why it still is not autofocus.
