Description
The OPT-RN03980-187-072287M42 is listed in OPT's series “Rhino Bi-Telecentric” with magnification 0.3980 ×, aperture F7.0 - F32, image circle Ø28.7 mm. Also: working distance 187 mm ± 3 mm, M42.
The Rhino series is telecentric on both sides: perspective and focus errors disappear, and the object is imaged at its true size. Large apertures bring plenty of light onto the sensor, and the field of view ranges, depending on the model, from Ø36 to Ø150 mm - for sensors from 1/2.5" to Ø82 mm. It is made for metrology: edges, holes, contours and height offsets that must be measured regardless of the object's position.
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. The dimensional drawing and the STEP model are included.
