Imaging optics for small spot sizes
specbos 1211-2 and spectraval 15x1 in its standard configuration can measure in Radiance mode only with diameters of 4 mm and more. Applications as the measurement of small segments of displays or small sized OLEDs may need smaller diameters. Therefore, JETI offers three imaging optics to reduce the measuring diameter. Their data are shown in the following table:
|Model||Measuring distance (from front end of the optics)||Field of view||Length of optics||Part number|
|Focus 3mm||70 mm||2.1°||77 mm||ACC 006/1||ACC 006/1UV||ACC 006/2|
|Focus 1mm||26 mm||1.9°||26 mm||ACC 007/1||ACC 007/1UV||ACC 007/2|
|Focus 0.5mm||46 mm||0.6°||77 mm||ACC 008/1||ACC 008/1UV||ACC 008/2|
|Customer specific design||ACC 009/1 d_D (measuring diameter d (mm) with measuring distance D (mm), d > 0.5 mm)||on request||ACC 009/2 d_D (measuring diameter d (mm) with measuring distance D (mm), d > 0.5 mm)|
It is only possible to use the imaging optics with specbos1211-2 focus/ specbos 1211UV-2 focus respectively spectraval 15x1 focus. Therefore, it is not possible to equip an existing standard model with these optics.
