Can your patternless edgers interface with other types of tracers or can your tracer interface with other edgers?

Yes. Our Patternless Edgers and 2G Generator are DCS-compliant and can interface to other equipment through software that meets these standards. For equipment that does not meet these standards, a gateway device can be used to achieve an interface.

The 7E can accommodate most types of blocks used with the industry; geometric or optical center blocking can be used. Our 3B finish blocker is fully interfaceable to the 7E.


Will I need a compressor?

The 7Ex  does not require a compressor, The Horizon II Edger, and 2G Generator require compressed air in order for the chuck system to operate.


Can the Horizon II be converted to a patternless edger?

We do not offer or support this type of conversion as it does not provide 3-axis edging.

Foam or plastic laps can be processed on the 2G.


Can the 2G be used with wax or metal blocking systems?

The 2G contains software that accommodates either blocking system.


What is the time frame for delivery after placing an order?

Typical lead-time is 4-6 weeks. Requests for special arrangements are accommodated when possible.



What is OMA Protocol?

Data Communication Standard (DCS). Members of the Optical Industry Association's Lens Processing Technology Division agreed in 1994 to develop standards for data communication between equipment and computer systems in the ophthalmic laboratory. These members wrote a mission statement and formed a task group of the most qualified experts in the industry to develop the standards as follows.


Mission Statement

It is the expressed intent of the Optical Industry Association and its Lens Processing Technology Division to establish a standard system of data communication that provides for compatibility in the inter-connection of lens processing equipment. This system will enhance buyer confidence in the equipment and improve the quality and performance of lens processing systems in our customer's shops and laboratories. The standards will be supported through participation of the members and will be promoted by the Optical Industry Association to users of lens processing equipment.


From this effort, the Optical Industry Association published in 1996 version 1.0 of the Standard for Device Communications This standard specifies a cable and connector to link equipment and computers and a communication protocol. The initial version has now been updated and re-issued under version 3.0. We will review and update this standard as needed to reflect technological advances and the lessons we learn through use of the standard.


Optical Industry Association members agree to support these voluntary standards through participation in their use. Use of the standards is not restricted to members of the Association and others are encouraged to use them. The present standards were reviewed and approved by the OMA members with the belief that these standards fulfill the mission and will serve the industry well in the years ahead.


How are operators trained?

Installation and training is included with purchase (within the continental United States) and can be tailored to newcomers within the industry or highly experienced personnel.


Are cabinets available?

Cabinets for our edgers or generator can be purchased for all equipment. In the event that you have existing countertops or cabinets, a benchtop diagram can be provided to determine if you have the appropriate benchtop space.


Does the equipment come with a warranty?

All new equipment comes with a one-year parts and labor warranty.


How can I see a machine?

Telephone and site references within your area are available upon request. The equipment is also exhibited at tradeshows throughout the United States.


What if I have questions after the installation of my equipment?

Just call our technical service department, and they will assist you and answer any questions you may have. Optronics is known for the highest standard of service in the industry.


What are the electrical requirements of the 7E Edger?

115 VAC 60 Hz 20A Electrical Supply. This is standard outlet power in the United States. The Optronics 7E Patternless Edger System should be on a dedicated circuit (no other electrical loads connected to the same circuit) to ensure a uniform, consistent power supply.


Is used equipment available?

From time to time, reconditioned units are available. Availability is limited and is "first come, first serve". Pricing is dependent upon the age and condition of the equipment.
