Absorbing thin-film reflector (ATFR)
max. 63.5 mm | ATFR
In some laser cutting processes, a portion of the beam may reflect off the work piece and into the laser cavity, where it might disturb laser operation. In order to avoid such problems, an ATFR mirror can be inserted into the beam line. An ATFR mirror is characterized by high reflectance (typically 99%) for s-polarized radiation and low reflectance (typically less than 1%) for p-polarized radiation.
