Precision Optical Beam Generation
The YuLing collimator produces a stable parallel light field using a 1300 mm focal system with a Φ130 mm effective aperture. It provides ≤10″ parallelism and ≤1″ resolution, serving as a fundamental optical reference in testing, calibration, and research. By integrating adjustable reticle plates, the system simulates ideal light paths for optical material uniformity inspection, lens alignment, and optical instrument calibration in laboratories or production lines.
Accurate Collimator Lens Construction
Engineered with precision-ground glass and coated optics, the collimator lens maintains focus accuracy within ±1%. The 380–780 nm working wavelength range ensures compatibility with most visible light applications. The rigid optical tube minimizes deformation, while thermal compensation preserves beam parallelism during extended operation, ensuring consistent accuracy in metrology and imaging evaluations.
Comprehensive Testing Adaptability
When configured with optional accessories such as reading microscopes, front mirrors, or star pattern plates, the pinhole collimator enables multiple measurements—focal length, resolution, and surface quality assessment. Its modular interface allows quick conversion for different optical analyses, including lens quality, mirror flatness, and prism imaging.
Product Advantages
High-Definition Parallel Beam Output
The advanced optical alignment system provides stable, large-diameter collimation for complex testing environments. Each collimator is calibrated for precise beam uniformity, ensuring repeatable results across optical inspection and adjustment tasks.
Superior Light Transmission And Durability
The multi-layer coated collimator lens guarantees high transmission and minimal reflection loss across the visible spectrum. With aluminum alloy construction and precision sealing, the system resists contamination, vibration, and thermal distortion during continuous operation.
Professional Collimator Manufacture Quality Assurance
YuLing Technology’s position as a dedicated collimator manufacture ensures strict quality control from design to assembly. Each unit undergoes optical axis verification and mechanical alignment testing to meet laboratory standards, delivering reliability and long service life.
Applications:
The F-1300 Collimator Tube is an instrument used to generate a large-diameter parallel light beam, with a wide range of applications. By selecting different reticle plates and pairing it with various accessories such as observation microscopes, front mirrors, it can be used for the following purposes:
- As a fundamental tool for optical instrument alignment and adjustment.
- With the selection of a Borosilicate plate and paired with a reading microscope or measuring microscope, it can be used for measuring the intercepts and focal lengths of lenses and various objective lenses.
- With the selection of an appropriate resolution plate, and paired with an observation microscope and front mirror, it can be used for determining the resolution of lenses, prisms, plane mirrors, and various objective lenses, as well as for assessing image quality by observing resolution patterns.
- With the selection of an appropriate star pattern plate and paired with an observation microscope and front mirror, it can be used to evaluate the image quality of lenses, prisms, plane mirrors, and various objective lenses.
- By equipping the instrument with specialized mirrors and measuring eyepieces, it can be used to measure straightness or flatness deviations of rails and large flat surfaces.
- As a tool for aiming at long-distance targets.
Additionally, the F Series Collimator Tubes are essential test reference components for optical material uniformity checks and the calibration of various optical mounts. Therefore, they are commonly used in the production, research, and teaching of optical instruments.
Working Principle:
As shown in the figure below, the reticle serving as the target is uniformly illuminated by light source 1 through various color filters 2. If the reticle 3 is correctly positioned at the focal plane of the objective lens 4, the light emitted from the objective lens forms a parallel light beam, which is equivalent to light originating from infinity.
