This is a protective window optic for IR lasers. It measures 15.75mm in diameter and 1.1mm in thickness (dimension could be customized as per request). alexandrite quartz windows are useful to protect the more expensive lenses from smoke and debris. It's a high quality, brand new spare part originally intended for Sharplan / Lumenis medical lasers. Wavelength：Coated at 755nm, 1064nm, 755&1064nm

The vibrating mirror lens is applied inside the vibrating mirror system, mainly used for laser marking, laser drilling, laser internal adjustment, stage lighting control, etc. Its working principle is that the expanded laser beam is incident on the X and Y vibrating mirror lenses, which are controlled by software to reflect the angle of the vibrating mirror lenses, so that the two vibrating mirror lenses are deflected along the X and Y axes respectively, thus achieving the deflection of the laser beam. Main function: change the direction of the light path, commonly used in laser processing system vibrating mirrors, by changing the deflection angle of the vibrating mirror lens, so that the laser processing system can achieve the effect of regional processing.

柱面透镜是一种非球面透镜，可以有效减少球面像差和色差。

由两片不同材质的镜片组成，消色差镜片的作用是将两种不同颜色的光聚焦到同一点，或校正色差

透镜的用途非常广泛，从单光束的收集、精密成像到图像传输。
