Polarimeter The Large APEX
Bolometer Camera will be equipped with a polarimeter that follows the
scheme of PolKa (the MPIfR Polarimeter
fuer bolometer Kameras).
The design is based on the reflection-type half-wave plate: it will be part of the LABOCA optics in the telescope's Cassegrain cabin (see picture below).  LABOCA
