Photographic Estate Dimensional Analysis

 

Estate photographs were used in conjunction with a pair of calipers. Screen was adjusted until a common reference point was ascertained. The reference point used was the known dimensions of the LED PCB width, being 1.00". Length was determined by laying out the number of 5mm LEDs (16-qty) in a PCB CAD software. The distance from the first to the last was exactly 4.00". When the screw terminal via holes are added, the board length becomes 4.75" long. This is what decided the length of the acrylic body. 

Outer acrylic tube OD:  

Acrylic body bobbins OD: 2.75"

Acrylic "photon injection" length: 4.75"

LED groove width: 0.25

LED groove length: 4.00"
