Hoffman modulation contrast, which sees through plastic where DIC cannotDIC stops working the moment there is plastic in the light path, because the polarised beam it depends on is depolarised by the vessel. That rules it out for anything in a culture flask or dish. Hoffman modulation contrast produces comparable relief imaging without polarisation, which is why it remains the technique of choice for live cells in plastic.This TE200 arrives configured for that work: Modulation Optics 20x and 40x ELWD Plan Fluor Hoffman objectives alongside Nikon Plan Apo 2x and 10x DIC L, three filter cubes covering UV, green and red excitation, a mercury lamp power supply and the control box.Where it earns its place Live-cell observation through plastic flasks, dishes and plates Three-channel fluorescence across UV, green and red cube positions Micromanipulation and IVF-adjacent workflows built around Hoffman contrast A complete inverted platform for a lab starting a culture imaging bench Specifications Brand Nikon Model Eclipse TE200 MPN C-SHG1, TE-PS100 Format Inverted Contrast method Hoffman modulation contrast Filter cubes 96101M UV-2E/C, 96170M F HQ, 96171M R HQ Objectives Modulation Optics 20X ELWD Plan Fluor/0.4 HMC ∞/0-2 WD 7.4; Modulation Optics 40X ELWD Plan Fluor/0.6 HMC ∞/0-2 WD 2.7-3.7; Nikon Plan Apo 2x/0.1 ∞/- WD 8.5; Nikon Plan Apo 10x/0.45 DIC L ∞/0.17 WD 4.0 Country of manufacture Japan ConditionTested and fully functional.
