Fused Silica Aspheric Lens
Fused Silica has good UV and IR transmission performance, extremely small coefficient of thermal expansion. It has high stability and resistance to thermal shock over large temperature excursions, wide temperature operating range and high laser damage threshold. It is an excellent optical material under harsh environment.
JGS1 Fused Silica
Transparent in the ultraviolet and visible regions. Used for optics operating in the deep UV and the visible wavelength range.
JGS2 Fused Silica
Good UV and visible transmission. Used for condenser optics not concerned with scatter or distortion, high temperature and pressure applications, optical flats, microscope slides and sight glasses. Can be made in small diameters/dimensions that can be very thin and is free of bubbles. Cons include possible bubbles in larger dimensions/diameters.
JGS3 Fused Silica
Transparent in the ultraviolet, visible and infrared spectral regions. No absorption bands in the visible region. Outstanding optical characteristics in the deep UV and the IR wavelength range.
Aspheric lenses can increase the numerical aperture of a lens while minimizing system aberrations. And it has advantages such as improving the system imaging quality, simplifying assembly,increasing the system reliability,etc. Aspheric lens is ideal for light collection, projection, illumination, detection, and condensing applications.
