Single-Sided Telecentric Lens
Accessories
Teleconverters
When a closer view of objects is required, use a 59
LGZ-series teleconverter with your Invaritar
TM
large-
fi eld gauging lens. Mounted between the lens and the
camera, these teleconverters increase magnifi cation by
up to 2.0×. Their compact size has minimum impact
on overall lens/camera length. Teleconverters increase
lens f-number and contribute to overall image distor-
tion. Teleconverters cannot be used with some 3-CCD
color cameras.
Navitar off ers several diff erent accessories to enhance the performance of their Machine Vision telecentric lenses.
These include: teleconverters to increase magnifi cation, right angle attachments for viewing of objects up to 360
degrees about the optical axis, fi ber bundle collimators to provide collimated backlighting and anodized mounting
brackets for proper mounting of the Invarigon-R™ and Invaritar™ lenses.
