Product Overview

The Olympus TH4 (SKU: TH4-100) is the OEM transmitted-light illumination power supply for Olympus BX and IX series microscopes, and one of the most widely deployed halogen power supplies in laboratory and clinical microscopy. It delivers a stable, regulated 12V 100W output to the microscope lamphouse, ensuring consistent color temperature and brightness — both essential for repeatable imaging results and accurate color rendition in brightfield, phase contrast, and DIC applications. The TH4 supports connection of the Olympus TH4-HS hand switch (sold separately), enabling stage-side intensity adjustment without reaching for the base unit. As a genuine Olympus component, it integrates directly and reliably with BX and IX series lamphouses without compatibility concerns.
