New 4 banger P73 red i am working on. This will be 4 diodes knifed with no PBS. Everyone that has worked with these diodes know how much of a pain it is to align multiples with a high power telescope. In the past the diode had to be centered and rotated in the same place on the mount by loosening screws and manually moving it around. Both centering and rotating are fairly easy alone. Its when trying to do them at the same time the hair pulling frustration sets in. Just the slightest rotation can throw the spot off going through the tele. Second the distance from the collimation lens to the first correction lens has to be very precise. Moving the mount back and forth to accomplish this can be very trying to say the least. Trying some new ideas... I ended up using a round barrel lens holder mount. The diode block attaches to the rear of the barrel and can be moved x and y for centering. After this is done the diode block shouldn't have to be unscrewed. Next the barrel will be mounted in a stanchion style clamp. This will allow for rotation and easy adjustment back and forth. Most of the parts are machined. Hopefully everything works as planned (wish me luck ). I will post progress pics as I go.
