Technical Introduction of Protective Lens Assembly and Photoelectric Theodolite Barrel Structure
I. Protective Lens Assembly Technology
The protective lens assembly serves as the frontline protection for precision optical systems, featuring multi-layer composite construction that ensures both optical performance and physical durability. Manufactured from high-transmittance optical glass or quartz substrates with broadband anti-reflective coating, the assembly achieves over 98% transmittance in visible spectrum. Its hermetic sealing structure incorporates dustproof and waterproof capabilities, utilizing stress-relieving mounting technology between optical elements and metal frames through precision machining. The temperature resistance ranges from -40℃ to 120℃, with optional explosion-proof configuration using laminated composite technology for enhanced impact resistance. Standardized interfaces including threaded mounting and flange connection ensure compatibility with mainstream optical equipment.
Applications: Industrial inspection instruments, laser processing systems, precision measurement devices, medical imaging equipment.
II. Photoelectric Theodolite Barrel Architecture
The barrel structure employs modular layered design as the core load-bearing unit. The outer protective shell utilizes magnesium-aluminum alloy casting with topology optimization, achieving 35% weight reduction while maintaining structural rigidity (axial deformation <0.01mm/m). Internal subsystems integrate adjustable lens groups, beam splitter positioning mechanisms, and photoelectric sensor mounting bases. The thermal management system combines gradient thermal conductive materials to maintain internal temperature stability (ΔT≤±0.5℃/h). Dynamic compensation mechanisms optimized through FEM simulation effectively suppress micro-vibrations (amplitude reduction >92%). Specially designed heat dissipation channels with phase-change materials ensure stable thermal performance during continuous operation.
Key Specifications: Axial positioning accuracy ≤1μm, radial runout <5μm, resonant frequency >200Hz.
