A protractor reticle is a high-precision optical measuring component that combines angle measurement with optical reticle technology. It is typically made of high-purity optical glass, quartz, or a transparent polymer film, with precise angles, lines, or grid patterns etched onto its surface using micro-machining techniques.
1. Product Features
(1) High-Precision Reticle
The reticle lines, scales, and patterns are precisely sized, with uniform and clear lines.
The reticle spacing and line width can be customized to meet different measurement accuracy requirements.
(2) Rich Pattern Types
Various patterns can be created, including crosshairs, scale lines, grids, rings, concentric circles, and angle lines.
Custom reticle patterns can be designed according to the instrument's intended use.
(3) Excellent Optical Performance
Using optical-grade glass and other substrates, it has good light transmittance and flatness.
The reticle edges are clear, minimizing the impact on the field of view.
(4) Clear Lines and High Contrast
The reticle pattern has good contrast with the background, facilitating observation and identification.
Different colors or different transmission/reflection effects of the reticle can be selected according to the usage environment.
(5) Flexible Size Specifications
Different diameters, thicknesses, and external dimensions can be provided according to the instrument structure.
Supports circular, square, and special irregular-shaped reticles.
(6) High Customization
Customization is possible according to customer-provided drawings, samples, or technical parameters.
Customizable scale values, graduation values, line widths, patterns, positional accuracy, and marking content.
(7) Good Stability
With proper selection of the substrate and processing technology, it can meet the requirements for long-term use.
Suitable for laboratory, industrial testing, and precision optical instrument scenarios.
2. Main Application Areas
Due to its unique angle and linear measurement capabilities, the protractor reticle is widely used in many industries:
(1) Optical Measurement and Industrial Inspection: Used for measuring the geometric angles and bevel angles of micro-parts, electronic components, and cutting tool edges under microscopes.
(2) Document identification and forensic science: Commonly used in criminal investigation laboratories and document examination for microscopic analysis of fingerprint patterns, document handwriting deflection angles, passport anti-counterfeiting marks, etc.
(3) Scientific research and education: Used in fields such as biology and materials science to measure crystal structures, cell division angles, or microscopic morphological characteristics.
