UIS2 optics are designed to maximize S/N ratio and optical
performance for live cell fluorescence imaging.
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!

High N.A. objectives for fluorescence imaging
PLANAPO60XO and UPLSAPO100XO have outstanding N.A., 1.42
and 1.4 respectively, suitable for fluorescence imaging and bright-
field 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 340 nm.

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.
