Description
Olympus PM-CBAD Exposure Control Unit for Microscope Camera Stations AD
The Olympus PM-CBAD is a dedicated AD Exposure Control Unit designed for use with Olympus microscope camera stations. It provides precise control over film exposure parameters during photomicrography, including ASA film speed, reciprocity correction, exposure adjustment, and mode/exposure time settings. An LED numeric display shows ASA, frame count, and exposure time simultaneously. The front panel includes rotary knobs for Format, ASA, Reciprocity, Exposure Adjustment, and Mode/Exposure Time, along with dedicated buttons for Expose, Time Off/Winding, AE Lock, and Time Recall.

Applications
The PM-CBAD is part of Olympus's PM-series photomicrography system, used with research-grade and industrial Olympus microscopes equipped with camera port attachments. It was designed to automate and fine-tune film exposure when capturing images through a microscope — a common requirement in biological, materials science, and industrial inspection labs during the era of film-based microscopy. The unit interfaces directly with Olympus camera station modules (PM-LSS, PM-IVM, PM-FS, PM-PBS) and handles the calculations for reciprocity failure correction and proper film winding, which were critical for consistent results on slow-speed scientific films. Equipment of this type was widely used in academic, pharmaceutical, and semiconductor-inspection environments from the 1980s through the 1990s, before digital microscopy cameras became standard. Olympus PM-series accessories remain sought after by labs still running film-based photomicrography setups and by collectors of Olympus microscopy equipment.
This Olympus PM-CBAD Exposure Control Unit has been inspected and appears to be in good condition. The front panel controls, rotary knobs, and LED display all look intact with no broken or missing parts visible. The enclosure shows normal light wear consistent with lab use — minor surface marks on the case — but no cracks, heavy scratches, or damage. The rear panel connectors for PM-LSS, PM-IVM, PM-FS, and PM-PBS all appear clean and undamaged. Please view our photo set and contact us if you have any questions.
