    λ10 UV Fused Silica Plano-concave Lenses

    Excellent UV Transmission:

    UV fused silica, also known as UV-grade fused silica, is known for its high transmission in the UV range, typically from 190 nm to 2600 nm, depending on the coating. This makes it an ideal material for plano-concave lenses designed to work in the UV spectrum.

    Low Fluorescence and Laser-Induced Damage Threshold:

    UV fused silica exhibits virtually no laser-induced fluorescence, ensuring that the material does not emit light when excited by UV radiation. This is crucial for applications where fluorescence could interfere with measurements or imaging.

    It also has a high laser-induced damage threshold, allowing it to withstand high-intensity laser beams without degrading.

    Surface Quality and Accuracy:

    The λ/10 surface irregularity specification indicates that the surface deviations from a perfect shape are kept to within one-tenth of the wavelength of light used, typically at 633 nm. This level of precision ensures minimal wavefront distortions and optical aberrations.
