UIS2 Series


Superior S/N ratio delivers imaging excellence

Superior S/N ratio delivers imaging excellence
UIS2 objectives' fluorescence S/N ratio is improved by using selected low fluorescence glass material, and minimized autofluorescence obtained by anti-reflection coating and cementing material. Also numerical aperture (N.A.) has improved in addition to the reduction of autofluorescence. Weak fluorescence emissions are efficiently detected even from weak excitation light, which is friendly for the living cell.
The ideal fluorescence imaging of live cells with the UIS2 systems!

UPLSAPO series chromatic aberration compensation

Effective compensation for chromatic aberration up to near-infrared

The UPLSAPO series is the highest class UIS2 objectives, whose super apochromatic features effectively compensate for chromatic aberration from the visible spectrum all the way to near IR. This means that just one objective covers imaging from UV to IR range. The series also offers outstanding image clarity without color shift for multi-color observations using fluorochromes covering a wide wavelength spectrum.

High transmittance UPLSAPO100XO

High transmittances over a wider wavelength range

UIS2 objective achieves flat, high transmittance from visible to near-infrared light, thanks to new UW multi-coating which effectively cuts reflection over the super wide band spectrum. In particular, transmission in the near infrared range is significantly enhanced. Overall, performance all across the wavelength range is ideally suited for today's most demanding research applications.

What is UIS2 (Infinity-corrected Optics) ?

Infinity-corrected optics incorporates a parallel luminous flux between the objective and tube lens. This is known as the infinity space. Even if a mirror is inserted into the infinity space, there is no image distortion and no deterioration in image quality.
