New Super Apo Objectives Offer Outstanding Performance


Olympus Introduces UIS2 Optical System: Eco-Friendly Optics Offer Higher Transmission from UV to IR, Higher NAs, Improved DIC

MELVILLE, N.Y., October 25, 2004 - Olympus, a world leader and recognized innovator in developing new optical technologies, today introduced the new UIS2 Microscope Optical System. The optics allow virtually all Olympus microscope users to enjoy a host of benefits, including higher transmission from the ultraviolet (UV) light spectrum through the infrared (IR), improved differential interference contrast (DIC) performance, higher numerical apertures, aberration-free performance and infrared focus correction. Importantly, the new system is also eco-friendly, with a completely lead-free glass design.

"As optical innovators, we set out to design a system of infinity plan optics that provided superior performance while protecting the environment," said George E. Steares, group vice president of the Olympus Scientific Equipment Group. "Our new glass offers extraordinary performance enhancements while eliminating lead in the manufacturing process. And we have done it without driving up the cost."

The patent-pending glass designs offer users even clearer, brighter images, with higher signal-to-noise performance and better transmission beyond the visible spectrum for capturing low-light images. Researchers doing UV or IR fluorescence, as well as IR-DIC microscopy, will benefit from greatly enhanced transmission both above and below the visible spectrum. Importantly, the new objectives also offer apochromatic focus correction in the near IR spectrum. DIC image contrast is enhanced and images are more even from edge to edge; the unification of back focal plane positions results in fewer DIC prisms overall.

Olympus UIS2 optics have improved light gathering ability, with higher NAs overall, and some offer improved working distances as well. All the new optics are designed to fit on current Olympus microscope models without retrofitting.

At the pinnacle of performance are the UIS2 Super Apochromat objectives, offering exceptional Apo correction from the UV range through the IR. Parfocal for both visible and IR imaging, they are designed for the most demanding research applications. Among the outstanding optics in this line are 40x 0.90 NA, 60x oil 1.35 NA, 60x water immersion 1.2 NA, and 100x oil 1.4 NA objectives, along with 10x and 20x Super Apos. Other key new objectives designed for live cell microscopy include a Plan Apo N 60x 1.42NA with enhanced UV and IR correction and a U Plan Fluorite N 40x 1.30 NA with 200Ám of working distance. These join the line of outstanding optics Olympus already has available for researchers doing live cell work, including the 20x 0.8 NA U Plan Apo oil and 40x 1.35 NA UApo/340 oil.

The UIS2 series includes additional UPlan Fluorite N objectives designed for research fluorescence, polarized light microscopy and DIC, including a 60x dry objective; a new line of polarized light and phase contrast objectives; a full set of PlanC N optics that will replace achromat objectives for basic brightfield work; and a completely new series of clinical objectives for diagnosticians and educators, among many other optics.

Researchers can now find data and transmission curves for many key UIS2 objectives online at the Olympus website, http://www.olympusamerica.com/uis2. "We know how vital it is to have complete information on optical system performance when designing experiments," said Steares.

"Olympus is dedicated to environmentally conscious product design," added Steares, "and we continue to enhance optical performance and bring cost benefits to the user - at the same time we develop safer technologies."
