   Limited Power of Attorney for Section 16 Filings

	I, Michael Joyner, of Rochester, MN, do hereby make,
constitute and appoint Patricia M Kehe and Thomas Leonard, and
each of them acting individually, my true and lawful attorneys
for the purposes hereinafter set forth, effective as of this
15th day of August 2013.

	References in this limited power of attorney to "my
Attorney" are to each of the persons named above and to the
person or persons substituted hereunder pursuant to the power
of substitution granted herein.

	I hereby grant to my Attorney, for me and in my name,
place and stead, the power:

1.	To execute for and on my behalf, in my behalf, in my
capacity as an officer, director or stockholder of
Dynasil Corporation of America, a Delaware corporation
(the "Company"), Form 3, Form 4, and Form 5, and all
and any amendments thereto, in accordance with Section
16(a) of the Securities Exchange Act of 1934 and the
rules and regulations promulgated thereunder (the
"Exchange Act");

2.	To do and to perform any and all acts for and on my
behalf that may be necessary or desirable to complete
and execute any such Form 3, Form 4 and Form 5 or any
amendment thereto, and to timely file such schedule,
form or amendment thereto with the United States
Securities and Exchange Commission (the "SEC") and any
stock exchange or similar authority; and

3.	To take any other action of any type whatsoever that,
in the opinion of my Attorney, may be necessary or
desirable in connection with the foregoing grant of
authority, it being understood that the documents
executed by my Attorney pursuant to this limited power
of attorney shall be in such form and shall contain
such terms and conditions as my Attorney may approve.



      I hereby grant to my Attorney full power and authority to
do and to perform any and every act and thing whatsoever
requisite, necessary or proper to be done in the exercise of
any of the rights and powers herein granted, as fully to all
intents and purposes as I might or could do if personally
present, with full power of substitution or revocation, hereby
ratifying and confirming all that my Attorney shall lawfully
do or cause to be done by virtue of this limited power of
attorney and the rights and powers herein granted.  I
acknowledge and agree that neither my Attorney nor the Company
is assuming any of my responsibilities to comply with the
Exchange Act.

      This limited power of attorney shall remain in full force
and effect until I am no longer required to file any of Form
3, Form 4 or Form 5 with respect to my holdings of, and
transactions in, securities of the Company, unless earlier
revoked by me in a signed writing delivered to each of my
Attorneys and any substitutes therefor, if any.  This limited
power of attorney may be filed with the SEC as a confirming
statement of the authority granted herein.

      IN WITNESS WHEREOF, I have hereunto set my hand to this
