The SPX030AR.1 High Energy Fused Silica Lens is an AR.1 coated (at 1064 nm), 1 inch (25.4 mm) diameter, HPFS 7978 plano-convex lens with an effective focal length of 350.0 mm at 546.1 nm. It is designed for high frequency laser pulses where standard grade fused silica does not perform very well. The special grade fused silica Corning HPFS 7978 has very low hydroxyl molecule presencecompared to standard fused silica material, which results in less absorption of laser light and greatly reducing the chances of internal damage.

SPX030AR。1高能熔融二氧化硅透镜为AR.1涂层(1064 nm)， 1英寸(25.4 mm)直径，HPFS 7978平凸透镜，有效焦距350.0 mm, 546.1 nm。适用于标准等级熔融石英性能不佳的高频激光脉冲。特殊牌号的熔融二氧化硅康宁hpfs7978与标准熔融二氧化硅材料相比，羟基分子含量非常低，导致激光吸收更少，大大降低了内部损伤的几率。
