A horizontal transmission micrometer reticle is a high-precision accessory designed specifically for optical measurement. It typically uses high-quality optical glass (such as Schott glass or quartz glass) as a substrate, and employs ultra-precision photolithography or vacuum coating technology to etch a horizontal line with specific graduations (e.g., 1 mm divided into 100 equal parts) onto its surface. The horizontal transmission micrometer is usually mounted on the real image plane (or the intermediate image plane of the optical system) inside the eyepiece of a microscope. When observed through the eyepiece, the horizontal graduation line perfectly coincides with the sample image formed by the microscope objective (confocal), thus enabling direct reading of the horizontal dimensions of minute objects.
1. Product Features
(1) High Precision and Fine Grading: Utilizing high-magnification photolithography, the reticle is extremely fine, uniform, and has sharp edges, remaining clear and burr-free even under microscopic magnification, ensuring accurate measurement results.
(2) Confocal Imaging with No Parallax: Mounted on the real image plane of the eyepiece, the scale and the measured object are on the same focal plane, effectively eliminating measurement errors caused by parallax.
(3) High thermal stability: Utilizing a high-quality optical glass substrate with a low coefficient of thermal expansion, it maintains extremely high dimensional stability even under fluctuating laboratory temperatures.
(4) Excellent optical transmittance: The substrate has high transmittance, and the metal coating layer has good shading and low reflectivity, without affecting the original illumination and imaging contrast of the optical path.
2. Typical Application Areas
(1) Biological and medical testing: Widely used in biological microscopes to measure cell diameter, microbial size, tissue fiber width, and the geometric dimensions of specific components in blood smears.
(2) Industrial micro-measurement and quality control: Used for horizontal line spacing and dimensional detection of electronic components, precision mechanical parts, micro-gaps, and micro-machined surfaces.
(3) Optical laboratories and teaching: Used in optical, physics, or biological experimental teaching in higher education institutions to demonstrate and teach the basic principles of micro-measurement.
