Olympus U-LH100HGAPO 100 Watt Mercury Lamphouse

The Olympus U-LH100HGAPO is a 100W mercury arc lamphouse with apochromatic (APO) chromatic correction for Olympus BX, IX, and MX series fluorescence microscopes. It is the premium version of the standard U-LH100HG lamphouse — the APO designation indicates that the collector optics are chromatically corrected, minimizing chromatic aberration in the excitation light path and delivering spectrally accurate illumination across the full UV and visible range. This chromatic correction is particularly important in multi-channel fluorescence imaging, where excitation light at different wavelengths (e.g. UV for DAPI, blue for FITC, green for TRITC) must be delivered with consistent optical quality to ensure accurate co-localization, color fidelity, and quantitative fluorescence measurements. The 100W mercury arc lamp provides high-intensity, broad-spectrum output with characteristic emission peaks at wavelengths aligned with the excitation spectra of all common fluorophores — including DAPI, FITC/GFP, TRITC/mCherry, Texas Red, and others. Compatible with BX, IX, and MX series microscopes. This unit is in excellent condition at a significant discount from the list price. Note: mercury arc lamps require careful handling and disposal in accordance with local regulations due to mercury content.
