Opticon is eager to help you integrate the LH2 imager into your application.  Our technical support staff 

is available to answer any questions or work with you to adapt the imager to your specific situation.  

We are happy to answer your questions, assist in configuring and positioning the imager for optimum 

operation, and help resolve any problems you encounter.  Call us at 1 (800) 636-0090.

The most common reasons for poor scanning performance are listed below:

• Bar codes are not positioned at the focal distance of the imager.

• Specular reflection is impacting the imager.  Change the angle/position of the imager or the 

bar code.

• Poor quality of printed bar codes.  Bar codes are out of specification.

• The paper on which the bar code is printed is highly reflective or has a glossy finish causing 

light to be reflected into the imager.

• The distance from the imager to the bar code is not suitable for the density of the bar code.  

Or the density of the bar code beyond the imagers capability.
