Descripción
A technique for obtaining an ideal two-mirror coude system with no
instrumental polarization is described. A half-wave plate positioned
between the two mirrors with the proper orientation produces the desired
effect. The level of spurious polarization is limited by the
characteristics of the retarder and the similarity of the mirrors. The
telescope design and accuracy are discussed.
