High Precision Cross-Shaped Bifurcation Lines Reticle

A crosshair reticle, also known as a crosshair reticle, is a high-precision optical element. It uses high-quality optical glass as a substrate and employs ultra-precision photolithography or vacuum coating technology to etch lines containing a cross and specific branching patterns onto its surface. Crosshair reticles are typically installed in the optical path of optical instruments (such as the real image plane of a microscope eyepiece, a sight, or a collimator) to achieve high-precision visual alignment, centering, and optical coordinate reference.

1. Product Features

(1) High Precision and High Resolution: The lines are extremely fine and straight with sharp edges, meeting the alignment requirements of high-magnification optical systems and demanding microscopic measurements.

(2) Optical Confocal Performance: When installed on the real image plane of a microscope or telescope, the reticle can achieve perfect synchronous focusing with the image of the object being measured, eliminating parallax.

(3) Excellent Light Transmission and Imaging Performance: Utilizing a high-purity optical glass substrate, it has high light transmittance and will not cause halo or stray light interference to the original optical path system.

(4) Robust and Durable: The graduated film layer is firmly bonded to the substrate, possessing strong anti-friction and environmental adaptability, suitable for long-term use in laboratories and industrial environments.

2. Application Areas

(1) Optical Instrument Calibration and Alignment: Widely used in microscopes, telescopes, theodolites, and photoelectric collimators as a reference for optical axis calibration and field-of-view center positioning.

(2) Industrial Machine Vision and Measurement: In automated visual inspection equipment, it serves as an optical coordinate system or crosshair reference point to assist in precise positioning and dimensional measurement.

(3) Laser and Optoelectronic Engineering: In laboratory optical path construction, it is used as a spatial reference line to assist in adjusting the beam path and position.
