Material

• JGS1 & JGS2 Fused Silica: These lenses are crafted from high-purity synthetic fused silica.

  • JGS1: Offers exceptional UV transparency (185–2500 nm), ideal for deep UV applications due to low hydroxyl (OH) content and minimal impurities.

  • JGS2: Features slightly lower UV transmission (220–2500 nm) but remains cost-effective for applications where extreme UV performance is not critical.

• Durability: Both materials exhibit high thermal stability, chemical resistance, and mechanical robustness, suitable for harsh environments.

Key Properties

1. Achromatic Design: Corrects chromatic aberration by combining two optical elements, ensuring precise focus of multiple wavelengths.

2. UV Transmission: Optimized for ultraviolet (UV) to near-infrared (NIR) spectrum, enabling high-energy laser compatibility.

3. Thermal Resistance: Low thermal expansion coefficient (≈0.55 x 10⁻⁶/°C) ensures stability under high-power laser exposure and temperature fluctuations.

4. Laser Damage Threshold: High resistance to laser-induced damage, critical for high-power UV laser systems.

5. Surface Quality: Polished to λ/10 surface flatness, minimizing scattering and ensuring beam integrity.

Function

• Laser Collimation: Converts divergent laser beams into parallel (collimated) rays, reducing divergence for precision applications.

• Chromatic Aberration Correction: Eliminates wavelength-dependent focusing errors, enhancing image and beam quality.
