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.

Cylindrical lens is an aspheric lens, which can effectively reduce spherical aberration and chromatic aberration.

Composed of two lenses of different materials, the purpose of the achromatic lens is to focus two different colors of light to the same point, or to correct chromatic aberration  

Lenses have a very wide range of uses, ranging from the collection of a single beam, precision imaging to image transmission.
