Zygo NewView 9000 3D Optical Profilometer Technology

Zygo NewView 9000 3D Optical Profilometer Technology

Basic information and model differentiation

1. Core model

The NewView 9000 system offers two basic configurations, with the core difference being whether it includes vibration isolation components:

Model (ZYGO P/N) Configuration Description Applicable Scenarios

6311-0100-01 Vibration sensitive environment with isolation system (such as laboratory multi equipment area, precision manufacturing workshop)

6311-0100-11 scenarios without isolation system (w/o isolation) equipped with external isolation platform (such as dedicated optical laboratory)

2. Principles of Measurement Technology

Adopting 3D Coherence Scanning Interferometer technology combined with Zygo's patented SureScan ™ Technology and Phase Shifting Interferometry enable non-contact surface height data acquisition:

Advantages: Balancing "large scanning range" and "high vertical resolution", it can measure various surfaces such as transparent/opaque, smooth/rough, etc., without the need for sample pretreatment.

Core hardware configuration

The hardware of NewView 9000 is designed around "high-precision optical imaging+flexible motion control", and the key component parameters are as follows:

1. Optical system

(1) Objective lens and zoom component

Specific parameter characteristics of components

Objective magnification: 1.0X -100X;

Type: Standard working distance, long working distance (optional);

Adaptability: Please refer to the "Nexview&NewView 9000 Series Objective Lens Chart" to cover requirements ranging from "low magnification for large field of view" to "high magnification for small field of view". Long working distance objective lenses are suitable for thick samples/complex fixtures

There are three options for installing the objective lens:

1. Single objective dovetail groove;

2. Manual Encoded 4-position Turret;

3. Motorized 4-position turret: The motorized turret supports automated objective lens switching and is suitable for batch sample measurement; Manual turntable has lower cost and is suitable for fixed scenarios

Optical zoom standard configuration: electric 3-digit coded zoom turntable (including 1.0X zoom tube);

Optional: 0.5X, 0.75X, 1.5X, 2.0X zoom components with zoom and objective lens to expand the field of view, coding design ensures repeatability of zoom position

(2) Field of view and lighting

Field of View Range: 0.04 × 0.04mm (high magnification objective+high zoom)~17.49 × 17.49mm (low magnification objective+low zoom), supports integrated field stitching, and can measure large-sized samples beyond the field of view;

Lighting system: White LED light source, equipped with manual field stop, aperture stop, and spectral filter, adjustable lighting intensity and spectral range, suitable for different reflectivity samples.

(3) Image acquisition

Measurement array (pixels): 4 options -1600 × 1200 (high-resolution), 1000 × 1000, 1000 × 600, 1000 × 200 (high-speed acquisition);

Sample observation: The Mx software has an integrated view window built-in, which displays sample images in real-time and assists in focusing and area positioning.

2. Motion control system

(1) Z-axis drive (focusing and scanning)

Component parameter function

Precision piezoelectric drive vertical scanning range: 150 μ m;

Control method: Closed loop capacitance gauge;

Safety design: including crash protection for high-precision vertical scanning, obtaining surface height data, and capacitance gauge to ensure scanning accuracy

Z-axis focusing stage stroke: 100mm;

Resolution: 0.1 μ m;

Focusing method: Electric manual/automatic focusing (with bandpass mirror focusing assistance) used for rough focusing and large height range adjustment of samples, with automatic focusing function improving operational efficiency

(2) Sample stage

Provide two configurations of "manual" and "electric" to meet different automation needs:

Stage type XY axis stroke tilt range (Tilt) Additional functions

Manual stage 100mm ± 3 ° foundation positioning, low cost

Electric stage 150mm ± 3 ° supports automated multi position measurement, with optional "coded XYZ" configuration to improve positioning repeatability

3. System control and software

Control computer: i7 processor, 1080P monitor;

Operating System: Microsoft Windows 10 (64 bit);

Software: ZYGO Mx v7.2.0 and above versions, supporting data acquisition, 3D/2D visualization, roughness analysis (such as Sq, Ra), step height calculation, and other functions.

Key performance indicators (under laboratory conditions)

The performance parameters are based on ISO standards (25178-601, 25178-604, 5436-1) and validated using standard samples. The core indicators are as follows:

Performance category specific parameter notes

Vertical scanning range of 150 μ m (piezoelectric drive); 20mm (Z-axis extended scan) extended scan suitable for large step height samples (such as 20mm thick samples)

Surface morphology repeatability (1) 0.08nm SmartPSI mode, 1-second acquisition, full field of view+3 × 3 median filtering

RMS roughness (Sq) repeatability (2) 0.008nm, also known as "vertical resolution", reflects the accuracy of surface detail measurement under the same measurement conditions as described above
