Telecentric Lens Options
Telecentric optics allow high accuracy, high throughput measurements within their field of view. For the highest throughput, select a telecentric lens with a field of view that encompasses the entire part to be measured. Or work at higher magnification, in which case M3 software will seamlessly combine FOV measurements with encoder readings from stage motion. The HDV500 system comes with a bayonet mount which allows telecentric optics to be changed by the user in seconds.
The following telecentric lenses are available with the system:
• 0.24X magnification with a 35 x 29 millimeter (1.4 x 1.1 inch) field of view
• 0.16X magnification with a 54 x 45 millimeter (2.1 x 1.8 inch) field of view
• 0.11X magnification with a 76 x 64 millimeter (3.0 x 2.5 inch) field of view
Zoom Lens
The HDV500 system includes the option for 6.5:1 manual zoom optics, with continuous zoom from 0.7X to 4.5X. Like the telecentric lens, the zoom optics are also bayonet mounted that can be changed by the user in seconds. Utilize zoom optics to measure large parts which would not fit into a single FOV, also for smaller parts where extremely high magnification is required.
