Automatic Exposure Body PM-PBK

Summary	Main Characteristics	Notes - Related Units
This Automatic Exposure Body automatically determines the correct exposure time. For vibration free operation the shutter can be operated using the Control Unit PM-CBK.	The PM-PBK incorporates an electronically controlled shutter in an automatic exposure range from 1/125 sec. to over 4 minutes. ISO setting and exposure adjustment is done using the control cluster on the exposure body. The estimated exposure time is indicated in 4-steps increments on a LED display. A focusing unit can be clamped into the front of the Exposure Body.	Among the focusing units available, the Screen Viewer PM-VSC is recommended for objectives lower than 4x, the Focusing Telescope PM-VS for higher objectives. It requires the Photomicro Adapter H and 35mm SLR Camera Adapter PM-D35S to mount an OM body. See also the description of the Semi Automatic Photomicrographic System PM-10AK.
