Olympus U-TLO 1.4 Oil Top Lens for Universal Condenser

The Olympus U-TLO 1.4 oil top lens is specifically engineered to provide maximum numerical aperture for Olympus universal condensers. This premium top lens uses oil immersion between the top lens and specimen slide to achieve a numerical aperture of 1.40, matching the NA of high-performance oil immersion objectives. The oil immersion design eliminates light loss at the glass-air interface, enabling maximum light-gathering capability and resolution. At 1.40 NA, this top lens enables optimal Köhler illumination for the most demanding high-resolution microscopy applications with 100x oil immersion objectives. Compatible with Olympus universal condensers, this top lens is essential for applications requiring maximum resolution and contrast. The high NA enables proper matching between condenser and objective numerical apertures, critical for achieving theoretical resolution limits. Factory-new condition ensures optimal optical performance and reliable operation for demanding research, clinical, and industrial microscopy applications.
