PF40-03-P01 In Stock

The PF40-03-P01 by ThorLabs is an excellent Ø4" protected silver coated mirror that boasts the highest reflectance in the visible to near Infared range spectrum among all metallic mirrors on the market. This mirror is particularly suitable for femtosecond pulsed laser applications due to its superb performance in the Infrared range.

The PF40-03-P01 comes equipped with a durable SiO2 overcoat with a thickness of approximately 100 nm to protect it from oxidation. Despite the protective overcoat, it is essential to avoid high humidity environments to prevent tarnishing. The PF40-03-P01 is easy to identify thanks to its item number engraved on the back of the substrate. However, it requires additional care due to its susceptibility to environmental damage and improper handling.

Fingerprints, abrasive surfaces, and high temperature or humidity environments can all damage the protective overcoat of the PF40-03-P01, leading to oxidation and degradation of the silver coating. To ensure optimal performance and longevity, it is recommended to follow standard practices for handling optics, such as using latex gloves or other protective covering to prevent residue and oil from coating the surface of the optic. Even with protective coverings, it is important to handle the mirror with care and avoid touching the mirrored face or edges. To guarantee maximum efficiency of the PF40-03-P01, it should be kept in areas with low levels of moisture and at an ambient temperature.
