Optiscan: Pentax ISC 1000 now in full-scale production
By RWE Australian Business News, 06 Mar 2006


Sydney - Monday - March 6: (RWE Australian Business News) -
Optiscan Imaging Ltd (ASX code: OIL) reports Pentax Corporation today
announced the sales release of the Pentax ISC 1000 flexible
endo-microscope.

Pentax's full-scale production release signals the start of
significant increases in Optiscan's revenues, margins and royalties.

"Full-scale production release by Pentax is a watershed event
for Optiscan and the commercialisation of its unique endo-microscope
technology," Optiscan CEO Mr Matthew Barnett said.

"The Pentax ISC 1000 endo-microscope will underpin Optiscan's
transition to a high-growth and profitable medical technology business."

The ISC 1000 flexible endo-microscope is a major product
initiative for Pentax.

It provides doctors with previously unobtainable levels of
magnification (1000x) and resolution (0.001mm), enabling them to observe
cells and cellular structures in real time during an endoscopic
examination.

Introducing endo-microscopy into the $US1.2 billion global
flexible endoscope market is a key component of Pentax's aggressive
growth plan for its Life Care Division.

Strong customer demand for endo-microscopy has already been
created through a combination of excellent clinical trial results,
publications in leading peer-reviewed industry journals, high-profile
presentations at international congresses and promotional activity.

Optiscan shares rose 2.5c to 38c this morning.
