 About Us

Optec, Inc. is located in Lowell, Michigan, just east of the Grand Rapids metropolitan area. For many years now the company has been in the forefront of research and development of astronomical, visibility, and video/CCD microscopy optical instruments for both amateurs and professional alike.

Optec was incorporated in 1979 and is the successor to DOAA Enterprises; a Detroit-based company founded by an Oakland University college student, Gerald Persha. Under the leadership of Persha, Optec has grown from a small basement operation to a corporation employing 8 technicians, machinists, and sales staff. Optec's roots are founded strongly in astronomical research instrumentation with products such as the SSP line of photometers, the patented TCF temperature compensating focuser and the recent addition of the Pyxis LE, a high precision, low-profile camera field rotator.

In addition to the astronomical product line, Optec designs and manufactures optical couplers for video/CCD microscopy, atmospheric visibility measuring instruments such as the Model LPV transmissometer and the NGN integrating nephelometer. These unique instruments are used to monitor the air quality in many of the national parks in the USA as part of the Improve Network.

Optec maintains and uses the Optec Observatory, a small observatory and testing laboratory for Optec's astronomical product line. Optec Observatory is fully computer controlled with separate control room and observing deck. Recent additions to the observatory now allow remote operations of the telescope, SSP photometer, and CCD camera control software.


The telescope at the Observatory is a Meade 10-inch LX-200, mounted on a special heavy-duty wedge manufactured by Optec. The pier for the telescope is pyramid shaped and was constructed using 45 bags of concrete mixed by hand on site. The telescope is exclusively used for equipment testing and electronic observations, and is only used manually for collimation and finder adjustment.

Optec Staff

Optec has a support staff of many diverse and qualified individuals who take great pride in their accomplishments with the company.

Gerald Persha

Jerry Persha is the founder of Optec. Though he is officially retired, Jerry is still an active member of the Optec team. Jerry formed the company while still a student at Oakland University.  DOAA Enterprises began as a basement operation in Royal Oak, Michigan and moved to Lowell in 1979 when Jerry incorporated the operation as Optec, Inc.

Jerry continues to provide all the optical designs for Optec's telecompressors, microscope optics, and visibility instrumentation.   Jerry offers guidance on new product designs and is currently active with the AAVSO using the SSP single channel photometers to achieve milli-magnitude photometry of variable stars.

Jeff Dickerman

Jeff Dickerman joined Optec in 1988 and is primarily responsible for sales, service, and new product development.  Jeff has been president of the company since 2008 when he and Tina purchased the corporation from Jerry Persha.
