I, Rafi Amit, certify
that:

1.           I have reviewed this
annual report on Form 20-F of Camtek Ltd.;

2.           Based on my knowledge,
this report does not contain any untrue statement of a           material fact or omit to
state a material fact necessary to make the statements           made, in light of the
circumstances under which such statements were made, not           misleading with
respect to the period covered by this report;

3.           Based on my knowledge,
the financial statements, and other financial information           included in this
report, fairly present in all material respects the financial           condition,
results of operations and cash flows of the Company as of, and for,           the periods
presented in this report;

4.           The companys
other certifying officer and I are responsible for           establishing and maintaining
disclosure controls and procedures (as defined in           Exchange Act Rules 13a-15(e)
and 15d-15(e)) for the company and internal control           over financial reporting
(as defined in Exchange Act Rules 13(a)  15(b)           and 15(d)  15(f) for
the Company and have:

a.
          Designed such disclosure controls and procedures, or caused such disclosure
          controls and procedures to be designed under our supervision, to ensure that
          material information relating to the company, including its consolidated
          subsidiaries, is made known to us by others within those entities, particularly
          during the period in which this report is being prepared;

b.
          Designed such internal control over financial reporting, or caused such
internal           control over financial reporting to be designed under our supervision,
to           provide reasonable assurance regarding the reliability of financial
reporting           and the preparation of financial statements for external purposes in
accordance           with generally accepted accounting principles;

c.
          Evaluated the effectiveness of the companys disclosure controls and
          procedures and presented in this report our conclusions about the effectiveness
          of the disclosure controls and procedures, as of the end of the period covered
          by this report based on such evaluation; and

d.
          Disclosed in this report any change in the companys internal control over
          financial reporting that occurred during the period covered by the annual
report           that has materially affected, or is reasonably likely to materially
affect, the           companys internal control over financial reporting; and

5.           The companys
other certifying officer(s) and I have disclosed, based on           our most recent
evaluation of internal control over financial reporting, to the           companys
auditors and the audit committee of companys board of           directors (or
persons performing the equivalent function):

a.
          All significant deficiencies and material weaknesses in the design or operation
          of internal control over financial reporting which are reasonably likely to
          adversely affect the companys ability to record, process, summarize and
          report financial information; and

b.
          Any fraud, whether or not material, that involves management or other employees
          who have a significant role in the companys internal controls over
          financial reporting.
