[PRODUCT OVERVIEW]
The Nikon EDF21000 TM 100x is a premium, high-magnification measuring microscope objective lens engineered specifically for industrial metrology, precision tooling inspection, and semiconductor QA/QC workflows. Unlike standard inspection objectives, the TM series is built as an optical ruler, delivering unparalleled dimensional accuracy for critical micro-measurements.
[KEY PERFORMANCE FEATURES]
* Object-Space Telecentric Design
Features a strict telecentric optical layout where principal rays remain perfectly parallel to the optical axis. This eliminates perspective errors ("near-large, far-small" effects) and ensures that magnification remains completely constant, even when the specimen surface has height steps or slight defocusing.
* Zero-Distortion for Metrology
Optimized for geometric purity. The edge-to-edge distortion is minimized to near-zero levels, allowing manual or automated measurement software (edge detection) to capture accurate X/Y dimensions consistently across the entire field of view.
* Pure Dry High-Magnification (Non-Oil)
Engineered as a high-resolution, pure Dry objective. Eliminates the risk of oil or water contamination on delicate parts, making it safe and efficient for inspecting cleanroom semiconductor wafers, precision optical components, and finished machined parts.
* Exceptional Planarity & Sharp Contrast
Delivers a flat field of view (Plan) with highly corrected chromatic and spherical aberrations. Specially coated to prevent internal glare and ghosting under vertical coaxial episcopic illumination, providing razor-sharp contrast on highly reflective metallic surfaces.
* Industrial Standard Compatibility
Designed for legacy industrial measuring systems (such as the classic Nikon MM series toolmakers' microscopes), utilizing a robust mechanical barrel and standard industrial mounting threads to ensure rigid, vibration-free integration.
[IDEAL APPLICATIONS]
* Toolmakers' Microscopes & Video Measuring Systems (VMM)
* Semiconductor Wafer Inspection & Critical Dimension (CD) Measurement
* Precision Micro-Machining & Geometry Verification
* Automated Machine Vision Edge-Detection Systems
