The exact number of photographic plates at the AIP is still unknown, but the total estimate is about 20.000 plates.

Currently, the following plate series have been identified and counted to different levels of exactness: direct plates (mostly):

Zeiss-Triplet (POT015, POT017 and POT009): 4693 plates (of these: 4251 plates POT015, 436 plates POT017 and 6 plates POT009) Zeiss-Triplet / Kapteyn Plates (POT015): 221 plates Great Schmidt Camera (POT050): 508 plates Small Schmidt Camera (POT025): 113 plates Schröder Refractor (POT030C): 55 plates Zeiss-Astro-Triplet (POT016): 182 plates Great Refractor / Comet Plates (POT080B): 125 plates Ross Camera (POTROS): 64 plates Schmidt Mirror (POT040B): 65 plates Photographic Refractor (POT032B): 151 plates Görz Refractor (POT050B): 11 plates Hartwig Plates (POT015B and POT017B): 16 plates Hartmann Plates (POT080A): 35 plates Great Refractor / Double-star Plates (POT080A): ca. 300 plates Wilsing Plates: ca. 300 plates Himmelskarten Refractor (POTW30): ca. 43 plates

spectral plates:

Spectrograph I (POTSP1): ca. 1000 plates Spectrograph III (POTSP3): ca. 950 plates Spectrograph VI (POTSP4): ca. 3200 plates Scheiner Plates: ca. 1200 plates Great Refractor (POT080B): ca. 300 plates Müller Plates: 91 plates Spectrograph (1888–1891): 238 plates

not clarified plates:

Ernostar Camera: 179 plates direct plates: ca. 2000 plates spectral plates: ca. 3000 plates
