Description
CBA13565 is a fixed magnification lens from OPT's CBA series: focal length 135 mm, magnification 0.15×, 0.30× or 0.50× (with extension tubes and focusing tube), working distance 1047, 599 or 421 mm, image circle Ø18.2 mm, aperture F6.5 - F75, C-mount.
The three magnifications are set with extension tubes and a focusing tube; each step has its own field of view (Ø121.3 mm, Ø60.7 mm, Ø36.4 mm), flange focal distance (50.2 mm, 70.5 mm, 97.2 mm) and object-to-image distance (1202.9 mm, 775.2 mm, 624.4 mm). Distortion stays below 0.11 %, 0.05 %, 0.01 %. Once set up, the image scale is fixed, which keeps measurement results comparable from batch to batch. Housing Ø46 × 106.55 mm, 0.27 kg, filter thread M39 × 0.5-6H, operating temperature -20 °C to +60 °C.
According to the manufacturer, the series resolves 145 lp/mm across the full field and suits cameras with pixels from 3.45 µm and sensors up to Ø18.2 mm; relative illumination is above 90 %, so brightness stays even out to the edge of the image. The long working distance leaves room for lighting and part handling. Typical tasks: inspection of PCBs, motor welds and heat sinks, and spacing checks on hardware.
When choosing a lens, what counts is the interplay of sensor size, pixel size, field of view and working distance - the focal length alone says little. If you tell us your camera and inspection task, we check the combination and, if needed, suggest suitable lighting to go with it.
