Applications

Ideal for deep ultraviolet (UV) spectroscopy, laser systems, metrology instruments, beam expansion/collimation, mask aligners, wafer inspection, and high-precision optical setups requiring low thermal expansion and high transmittance in UV bands. Used in semiconductor lithography, medical imaging, microlithography, and scientific research.

Key Features

✅ Ultra-high UV transmittance (down to 190 nm).
✅ Low coefficient of thermal expansion (CTE ~0.5×10⁻⁶ /°C).
✅ High homogeneity & minimal bubble/inclusion content.
✅ Precision grade surface accuracy (λ/8 or better interferometric flatness).
✅ Available uncoated or with advanced anti-reflection (AR) coatings.

Advantages Over Alternatives

�� Superior UV transparency vs. borosilicate or fused silica competitors.
�� Near-zero thermal drift ensures stable performance under temperature fluctuations.
�� Absence of birefringence eliminates polarization-dependent losses.
�� Chemical durability against aggressive cleaning agents.
�� Customizable dimensions for OEM integration.

Resulting Benefits

�� Maximized light throughput in UV systems → improved signal-to-noise ratio.

�� Enhanced system reliability in demanding environments (vacuum, cryogenics).
�� Absolute minimum wavefront distortion for high-fidelity imaging.
�� Long-term cost savings via extended service life & reduced maintenance.
