                  Thermo Electron Reports Cash EPS of $.21 and
                      Internal Revenue Growth of 14 Percent

WALTHAM,  Mass., April 26, 2001 - Thermo Electron  Corporation  (NYSE:TMO) today
reported  that diluted cash  operating EPS rose 31 percent to $.21 for the first
quarter of 2001, up from $.16 in the year-ago  period.  Internal  revenue growth
was 14 percent,  excluding  unfavorable  foreign  currency effects of 4 percent.
First quarter cash operating margins rose to 10.9 percent from 10.5 percent.*

     "Once again, we have delivered  strong organic revenue and earnings growth,
even as market conditions have become more  challenging," said Richard F. Syron,
chairman  and chief  executive  officer  of Thermo  Electron.  "We have a lot of
momentum  coming out of last  month's  successful  Pittcon  tradeshow,  where we
received  significant  attention  from customers and  competitors  alike for our
unified  branding  strategy and  new-product  introductions.  And we are focused
squarely  on  serving  our  customers  better by  continuing  to  integrate  the
businesses.  For example,  we have embarked upon an intensive review of our real
estate holdings around the world to combine locations.  One benefit is to reduce
costs and improve our  operating  margins.  Another is to make it easier for our
employees  to  collaborate,  which,  in turn,  will  enable  us to be ever  more
responsive to our customers' needs."

     Commenting on economic and market conditions and prospects, Mr. Syron said,
"We had  another  solid  quarter.  While there are  uncertainties  in the global
economy,  we are maintaining our targets of 8 percent  top-line growth and $1.00
cash  operating  EPS for  the  year.  We  believe  our  spectrum  of  instrument
technologies,  products,  and service  offerings  is a natural  hedge  against a
slowdown in any particular  industry.  However, we are keeping a watchful eye on
developments  in the markets we serve and are taking  swift action to adjust our
spending plans in those  businesses that are adversely  affected.  That said, we
are not sacrificing our  investments in  opportunities  that will lead to future
growth."

     The  company's  revenues for the quarter were $573  million,  compared with
$577 million in 2000. Comparative results were affected by the inclusion in 2000
of businesses  subsequently  sold,  and, to a lesser  extent,  foreign  currency
effects.  These decreases were substantially offset by internal sales growth. In
its discontinued operations, the company recorded a $66 million aftertax charge,
representing  a decline in the market value of the Thoratec  Corporation  shares
that  Thermo  Electron  received  from the sale of  Thermo  Cardiosystems.  This
resulted in a net loss of $45 million for the quarter.

Life  Sciences

Internal  revenue  growth for the Life  Sciences  sector was 12 percent  for the
first quarter, with revenues of $209 million.  Growth was driven by strong sales
of drug  discovery  tools,  including  our ion trap  mass  spectrometers,  which
increased 26 percent, as well as double-digit sales growth in sample-preparation
equipment.  Also  contributing  to sector  growth were higher sales of our rapid
diagnostic tests,  which increased 21 percent.  Cash operating income margin for
the sector was 16.1 percent for the 2001 quarter,  compared with 16.9 percent in
2000.  Improved  margins  in  sample-preparation  equipment,   biosciences,  and
clinical diagnostics were offset by substantial new investments in proteomics.

-------
* Cash operating EPS and cash operating margin, except where otherwise noted,
  exclude amortization of goodwill and intangibles, restructuring and unusual
  items, the results of discontinued operations, the cumulative effect of change
  in accounting principle, and in 2000, extraordinary item. Internal revenue
  growth excludes the effects of foreign currency.




Optical Technologies

Internal revenue growth for the Optical  Technologies  sector was 36 percent for
the first quarter,  with revenues of $140 million.  Revenues at  Spectra-Physics
rose 44 percent, with growth in the balance of the sector up 31 percent.  Growth
drivers included strong demand for solid-state  lasers used in industrial,  R&D,
and  life  sciences   applications;   increased  sales  of  photonics  products,
particularly  diffraction gratings for photolithography and fiber-optic systems;
as well as increased  sales of molecular  beam epitaxy  systems.  Cash operating
income  margin for Optical  Technologies  was 9.8 percent for the 2001  quarter,
compared  with  9.3  percent  in 2000.  Margins  improved  significantly  in our
Photonics  and  Semiconductor  divisions,  offset  in part by lower  margins  at
Spectra-Physics due to heavy investments in new-product introductions.

Measurement and Control

Internal  revenue growth in the Measurement and Control sector was 6 percent for
the quarter, with revenues of $228 million. Growth was driven by strong sales of
environmental-monitoring  instruments  used in  emissions-trading  programs  and
utility plant  upgrades,  and increased  demand for natural gas  flow-monitoring
instruments  to the energy  industry.  This was offset by  weakness  in sales of
process  instruments to the U.S. steel industry and the food processing  market.
Cash operating  income margin  increased  substantially  to 11.3 percent for the
quarter,  up from 9.4 percent in 2000,  due to sales  growth and  cost-reduction
measures  initiated  in the  fall of  2000,  as well as a  favorable  comparison
resulting from the divestiture of lower-margin businesses.
