Description
Hitachi 139-0150 Filter Compartment Spectrophotometer Accessory Tokyo Japan
The Hitachi 139-0150 is a filter compartment module designed for use with Hitachi spectrophotometer systems. This self-contained unit houses a rotary optical filter selector assembly — incorporating black and red optical filters — along with internal lamp or light-source components, and connects to the host instrument via an attached multi-conductor cable terminating in a 4-pin circular connector. It is manufactured by Hitachi, Ltd. of Tokyo, Japan and carries the reference designation GE 429723.

Applications
Filter compartments of this type are used in Hitachi spectrophotometer and spectrophotometric analysis systems to select the appropriate optical filter for a given measurement range or wavelength band. In these instruments, the filter compartment sits in the optical path between the light source and the sample or detector, and the rotary filter wheel allows the operator to switch between filters — typically to block or pass specific wavelength ranges, reduce stray light, or match the detector sensitivity range. Hitachi produced a broad line of UV-Vis spectrophotometers and related optical analytical instruments from the mid-20th century onward, with components like this compartment used in laboratory, industrial quality control, and research settings. Units of this generation, identifiable by the painted aluminum construction and circular multi-pin connector style, date from the 1980s era of Hitachi's analytical instrument production. Replacement and spare filter compartments are sought by labs maintaining older Hitachi spectrophotometer systems.
This Hitachi 139-0150 Filter Compartment has been inspected and appears to be in good used condition. The housing shows typical wear consistent with laboratory service use, including light scuffs and surface marks on the painted metal enclosure. Internally, the filter wheel assembly with black and red optical filters is intact, and the rotary selector mechanism is present. The attached multi-conductor cable with 4-pin circular connector is included. Please view our photo set and contact us if you have any questions.
