Product Description
Like all plano-concave lenses, these lenses have negative focal lengths and can be used to diverge collimated beams; in this case, the curved surface should face the source in order to minimize spherical aberration. In addition, they can be employed to offset the effects of spherical aberration caused by other lenses in an optical system. ZnSe lenses are particularly well suited for use with high-power CO2 lasers.
This substrate scratches easily and should be handled with care. When handling optics, always wear gloves. This is especially true when working with zinc selenide, as it is a hazardous material. For your safety, please follow all proper precautions.
- deal for CO2 Laser Applications Due to Low Absorption Coefficient
- Use to Diverge Collimated Incident Light
- Focal Lengths from -25.4 mm to -200 mm Available
