Anti-reflective Coating Optical Glass Substrates For Inspection Systems
Material:
Base Substrate: High-precision borosilicate glass (e.g., Borofloat 33) or fused silica, selected for exceptional flatness, thermal stability, and chemical resistance.
Coating Technology: Multi-layer dielectric coatings (e.g., MgF₂, SiO₂, Ta₂O₅) applied via precision magnetron sputtering or vapor deposition.
Design Types: Customizable as broadband AR (visible-NIR spectrum) or V-coating (single-wavelength optimization).
Key Properties:
Ultra-Low Reflectance: Achieves <0.5% surface reflectance (vs. 4-8% for uncoated glass), maximizing light throughput.
High Transmission Efficiency: Delivers >99.5% light transmission in target wavelengths, minimizing signal loss.
Angular Stability: Maintains performance across 0-45° incidence angles critical for oblique imaging.
Environmental Durability: Resists delamination, humidity, and UV degradation under continuous operation.
Surface Quality: Sub-Ångstrom roughness (<5Å Ra) prevents light scattering artifacts.
Thermal & Chemical Resilience: Withstands cleaning solvents and thermal cycling (-60°C to +300°C).
Primary Function:
To eliminate stray reflections and maximize contrast in high-precision optical inspection systems.
Minimizes ghost images and flare caused by surface reflections.
Enhances signal-to-noise ratio for accurate defect detection.
Preserves light intensity across complex optical paths.
Main Applications in Inspection Systems:
Semiconductor Metrology:
Wafer defect scanners
EUV lithography inspection optics
Mask alignment systems
Automated Optical Inspection (AOI):
PCB assembly verification
Display panel defect detection (OLED/LCD)
Biomedical Imaging:
Microscope objectives for pathology
Flow cytometry lenses
Industrial Vision Systems:
Laser triangulation sensors
Machine vision lenses for assembly lines
Aerospace NDT:
Ultrasonic probe windows
Endoscope optics for turbine inspection
Photonics Testing:
Optical interferometer plates
Spectrometer windows
In essence: Anti-reflective Coating Optical Glass Substrates are precision-engineered components that solve reflection-induced accuracy issues in critical inspection systems. By applying advanced multi-layer dielectric coatings to ultra-flat borosilicate or fused silica substrates, they achieve near-invisible surface performance (<0.5% reflectance), enabling defect detection at micron/sub-micron scales. These substrates directly enhance the reliability of semiconductor metrology, AOI equipment, and biomedical imaging tools where every photon matters.
