Negative Focal Length: Our biconcave lenses have a negative focal length, making them ideal for diverging collimated light beams to a virtual focal point.

Versatile Applications: They are suitable for divergence of collimated or focused light beams, beam diameter modulation, correction of spherical aberration in optical assemblies, and increasing the focal lengths of lens groups.

Superior Material: UV Fused Silica (JGS1) offers exceptional transmittance to UV wavelengths, while also being widely transparent to visible and NIR wavelengths (200-2200 nm).

Robust Thermal Properties: These lenses exhibit high-temperature endurance and low thermal expansion, ensuring stable performance in harsh working conditions.

Additional Benefits: UV-fused silica lenses have few bubbles/striae, high homogeneities, chemical inertness, mechanical hardness, and advantageous birefringent properties.

Applications: Optical Instruments, Beam Expanders, Aberration Correction, Focal Length Adjustment, UV Applications, etc.
