Schematic

below is an engineering diagram of the dimensions of the target actual manufactured dimensions may vary slightly revision a for dt ntpt targets with serial number tp26007 and lower and dt ntvt targets tp25007 and earlier revision b in 2026 the design of the target was slightly tweaked it was found that the outer patches proximity to the edge, combined with slight tolerances in manufacturing, could lead to patches being slightly obfiscated, and for a very slightly different amount of illumination to reach those patches from parts of the light source that were at a strong angle in dt nexus we implemented simple code to ignore the outer part of these outer patches so no real world impact was expected, but it still seemed prudent to condense the patch area modestly to allow more margin here is the schematic for dt ntpt targets with serial number tp26008 and higher and dt ntvt targets tp26001 and higher
