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.

High N.A. objectives for fluorescence imaging

and 1.4 respectively, suitable for fluorescence imaging and brightfield observation as well. In addition to their high fluorescence S/N ratio, both these lenses are able to handle UV excitation light. The UPLSAPO100XO provides a transmission of down to 340nm.

Low Auto-fluorescence Immersion Oil

The ability to reduce auto-fluorescence normally associated with immersion oil makes this product well suited for fluorescence microscopy.

High transmittances over a wider wavelength range

UIS2 objective for the IX71/81 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.

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.
