Cloudray F-Theta Lens 175x175mm For 1064nm Laser

The Cloudray 175x175mm f-theta lens is designed to deliver fast positioning and precise focal control for 1064 nm fiber laser systems. It supports high-precision marking and engraving across a defined field for repeatable results. The lens is built to withstand wear and temperature variations typical in laser processing environments, helping reduce thermal focus shift during continuous operation. Ideal for marking steel, aluminum, and other materials with consistent spot quality across the field.
Cloudray F-Theta Lens 300x300mm For 1064nm Laser

The 300x300mm f-theta lens expands the laser field, enabling rapid coverage of larger areas with high positional accuracy. This model emphasizes thermal stability and wear resistance, supporting demanding production environments. It is well-suited for multi-axis galvo configurations, enabling fast, repeatable marking and engraving with minimal focus drift across the field. Availability for various 1064 nm laser systems makes it a versatile choice for industrial applications.
Kinpthy Endoscope Camera With Light (16.4ft) Dual-Lens

While primarily a borescope, this Kinpthy configuration provides a long, flexible inspection path with LED illumination. Useful for verifying optical paths, alignment checks, and field verification in laser marking setups where access is limited. The semi-rigid cable and IP67 waterproof design add resilience for challenging environments, though performance is not a dedicated line-scan lens. Consider this option when you need in-situ inspection alongside line-scan workflows.
Kinpthy Endoscope Camera With Light (Single Lens)

Another Kinpthy option, featuring a single-view endoscope with integrated lighting. This model supports real-time image viewing via mobile devices and can help operators verify structural alignment or detect potential obstructions before initiating line-scan processes. Its semi-rigid design provides flexibility for tricky access points while maintaining waterproofing for challenging environments.
CZUR Lens Pro Portable Document Scanner

The CZUR Lens integrates image capture with software for document processing, which includes features such as intelligent cropping and multi-targeting. While not a traditional line-scan lens, it complements line-scan workflows by enabling rapid digitization and verification of sample materials prior to laser processing. Review software compatibility, scanning speed, and resolution to ensure it matches your line-scan system’s requirements.
Buying Guide: Key Purchase Considerations For Line Scan Lenses
- Field size and magnification: Larger fields reduce the need for repositioning, but may affect focus and resolution. Choose a lens with a field size that matches your typical work area.
- Wavelength compatibility: Most f-theta lenses are optimized for specific laser wavelengths (e.g., 1064 nm). Confirm compatibility with your laser source to ensure accurate focusing and minimal aberrations.
- Thermal stability: Laser processing generates heat; lenses with good thermal stability minimize focus drift during operation.
- Construction and durability: Look for wear-resistant coatings and robust housings to endure repetitive marking and high-speed scanning.
- Mounting and compatibility: Ensure the lens thread size and mounting interface align with your existing galvo or laser system.
- Maintenance and cleaning: Choose lenses that are easy to clean and maintain without sacrificing performance.
- Support and documentation: Manufacturer data sheets, installation guides, and technical support can significantly simplify integration.
- Use case fit: Distinguish between line-scan, field-scan, and general imaging lenses. Some products listed here are primarily for inspection or document capture, which may supplement line-scan workflows but are not strict substitutes.
When selecting a line scan solution, it’s important to compare optical performance metrics, installation requirements, and environmental tolerances. Cross-check lens specifications with your laser system’s galvo mirrors and focus tolerance to ensure consistent spot quality across the intended scan area. For multi-lens setups, plan for calibration procedures to align focal planes and maintain uniform scanning results across all lenses.
