PORTLAND, Ore. -- March 5, 2013

Electro Scientific Industries, Inc. (NASDAQ: ESIO), a leading supplier of
innovative laser-based manufacturing solutions for the microtechnology
industry, today announced the release of its Model 5335 UV Laser Drilling
System. As successor to the market-leading 5330 product family, the 5335
benefits from over 15 years of market experience and R&D efforts to deliver
the industry’s lowest cost of ownership in flexible circuit and general
micromachining applications through improved throughput and quality.

The 5335 brings state of the art performance to the flexible circuit and
general micromachining industry by use of its proprietary Third Dynamics™
technology. With this technology, the 5335 provides enhanced optical beam
manipulation beyond what is achievable with simple galvanometer control. Third
Dynamics™ enables industry-leading drill, routing, and skiving performance
through a combination of ESI's patented compound beam positioning and
solid-state optical technologies.

“We are very excited about the 5335’s upgraded productivity and convenient
operation,” said Jae-Hong Min, president of long-time ESI customer and partner
Korea Via Tech. After experiencing the benefits of the Model 5335 over a trial
period, this supplier to PCB manufacturing heavyweights such as Samsung and LG
Innotek placed a multi-system order. Min explained, “We expect that the 5335’s
high productivity and quality will positively impact confidence amongst
customers.”

The 5335’s patented solid-state beam steering technologies, advanced motion
control algorithms and sophisticated power control processes enable gains in
throughput and quality. Martin Orrick, Director of Product Development for
ESI’s Micromachining, Test and Inspection division, stated, “The 5335
represents the seventh generation in ESI’s single-head UV laser drilling
tools. ESI has engineered the system around building blocks field-tested in
hundreds of systems worldwide while further enhancing it with capabilities
never before seen in the laser material processing industry. As a market
leader in UV laser tools with over 1,000 such systems sold, we are convinced
that this is the most flexible and productive UV laser tool available today.”

The 5335 is currently available for sale and is priced to deliver the
industry’s lowest cost of ownership.
