The Olympus UIS2 series of infinity-corrected optics provides superior image quality and performance, with wavefront aberration control, excellent color reproducibility, and advanced coating technology that provides high transmittance that is flat over a wide range of wavelengths.       

Olympus offers two series of objectives for non-coverslip applications that require an increased distance between the focal plane and the tip of the objective, typically required for samples with irregular topography, delicate structures, or mechanical constraints of the overall optical assembly.       

Olympus offers a dedicated series of objectives designed for near-infrared (IR) imaging of features and defects beneath the surface of silicon and glass where transmittance is maximized at the near-infrared range. The semiconductor and photovoltaic industries use IR imaging for alignment, identification of sub-surface contamination, and critical dimension inspections. This series of optics employs a high NA that improves both the resolution and brightness of the IR image. Additionally, the 20x, 50x, and 100x objectives are designed with a correction collar that corrects for aberrations caused by the thickness of silicon and glass, improving overall contrast.       

This objective lens is designed for the Mirau style of white light interferometers and maintains a high level of temperature tolerance. Each lens can be adjusted to compensate for thermal drift using the built-in correction ring. The superior 0.8 NA provides improved light gathering performance, with a working distance of 0.7 mm.       

Olympus coverslip-corrected lenses are ideal for fluorescence imaging of live cells due to an improved fluorescence S/N ratio made possible through the use of low fluorescence glass material and minimized auto-fluorescence obtained by anti-reflection coating and cementing material.         Objective transmittances are high and flat throughout the visible and near-infrared wavelengths due to a UW multi-coating that cuts reflection over the super-wide band spectrum.       

Immersion objective lenses provide the highest level of chromatic correction and resolution available from Olympus. Oil immersion objectives are available for both coverslip and non-coverslip samples. Water immersion objectives are available for applications requiring the use of coverslips.
