UV Fused Silica Glass Discs for Precision Optics & Laser Systems
Material
UV Fused Silica: Synthetic glass composed of high-purity silicon dioxide (SiO₂), optimized for ultraviolet (UV) transmission.
Grades: Includes JGS1 (deep UV transparency, 185–2500 nm) and JGS2 (220–2500 nm), balancing performance and cost.
Purity: Low metallic impurities and hydroxyl (OH) content ensure minimal absorption in UV spectrum.
Key Properties
UV Transparency: Exceptional transmission from deep UV to near-infrared (NIR), critical for UV laser applications.
Thermal Stability: Low thermal expansion (≈0.55 x 10⁻⁶/°C) resists deformation under high-power laser exposure or temperature shifts.
Chemical Resistance: Inert to acids, solvents, and plasmas, ideal for harsh industrial environments.
Laser Damage Threshold: High resistance to laser-induced damage, suitable for pulsed and continuous-wave lasers.
Surface Quality: Polished to λ/10 flatness with minimal subsurface defects, ensuring precision beam control.
Homogeneity: Uniform refractive index (±5 x 10⁻⁶) for distortion-free optics.
Function
Optical Windows: Transmit UV light while protecting sensitive components from environmental factors.
Substrates: Serve as bases for coatings (anti-reflective, dielectric) in mirrors, filters, or beam splitters.
Beam Delivery: Maintain beam integrity in laser cavities, collimators, and focusing systems.
Optical Flats: Provide reference surfaces for interferometry and calibration.
Applications
Laser Systems: UV excimer lasers, Nd:YAG systems, and femtosecond lasers for beam guidance and output windows.
Semiconductor Lithography: UV light delivery in photolithography masks and stepper systems.
Precision Optics: Telescope mirrors, microscope slides, and interferometer components.
Medical Devices: UV sterilization equipment, laser surgery tools, and diagnostic imaging.
Aerospace & Defense: UV sensors, LIDAR systems, and high-energy laser (HEL) applications.
Research: Spectroscopy, UV photonics, and quantum optics experiments.
