Abstract: An optical attachment unit is described which can be inserted reversibly into the detection light path of a confocal optical microscope, which has the effect of modifying the magnification of the specimen at the level of the detector iris. This modification consists in the preferred form of a demagnification, so that high sensitivity is obtained at the expense of confocal function, as is required for multiphoton imaging and other purposes. No optical telescope or other imaging system used for confocal function is disturbed or removed by the operation of inserting the unit, so that the confocal function can be restored reproducibly and rapidly.
