OEM Round Flat Optical Window - Glass Lens for Machine Vision & Laser Applications
Optical-Grade Glass: Primarily borosilicate (BK7/K9) or UV-grade fused silica, selected for thermal stability and transmission properties 46.
Specialized Coatings: Custom anti-reflective (AR), laser-line (e.g., 532nm/1064nm), or protective coatings to enhance performance 45.
Customizable Substrates: Optional infrared (Ge, ZnSe) or crystal materials (sapphire) for niche applications .
High Transmission: >99% light transmission (coated) with minimal scatter or wavefront distortion (<λ/10 @633nm) .
Thermal/Mechanical Resilience: Resists thermal shock (ΔT >150°C), chemicals, and impacts (IK-rated) for harsh environments .
Precision Tolerances: Diameter: ±0.01mm, Thickness: ±0.01mm, Parallelism: <5 arcsec .
Surface Quality: 10-5 scratch-dig or better, RMS roughness <0.5Å for laser safety .
Beam Integrity Maintenance: Transmits light without distortion for accurate imaging/laser focusing .
Component Protection: Seals sensors/lasers from dust, debris, and corrosive agents (IP65/IP66 compatible) .
