POINT TRANSFER DEVICE
Progress Report 552 & 552A for February 1966
Work'during February consisted of completing assembly
and,adjustment motions and commencing system debugging on the
Point Transfer Device. Optics and mechanisms are all operating,
but require miscellaneous work to clean up system for acceptance
checkout.
OBJECTIVE ASSEMBLIES
Both objective assemblies installed and all objective
and system optical adjustments completed. Recently reworked
beam,splitters and lasers were installed and successfully marked
film. However, some debugging still needed because output of
laser declined after a few days use to a less than desirable level
for consistent marking quality. Laser reticle drive electronics
modification is almost complete. New reticle indexing device is
somewhat slower, but appears to handle load well.
Laser alignment is now being checked by a short length
of rigid fiber optics replacing the crystal, but some further im-
provement is seen to observe image accurately. The sole adjust-
ment to be made and monitored is a prism above each laser head
where an accurate image brightness and symmetry maxima has to be
obtained to utilize all of laser output possible. The previously
completed adjustment of the beam splitter established the optical
axis through the laser relay lens and with it focus of the retical
station.

Laser output of 3 joules is seen necessary for reasonably
good film marks and is highly dependent on the cavity finish,
laser crystal temperatures, lamp condition and capacitor bank
charge. The silver plating of the cavity became easily tarnished
and has been refinished several times during the.last month. A
solution here seems to be a basically more reflective finish such
as an evaporated aluminum film as used on front surface mirrors.
Laser head cooling means appears to be inadequate for rapid re-
cycling for maximum output. Enlarging cooling air inlet and out-
let ports of laser head may help this deficiency. For the lamp
condition status, we have not kept record of shots taken, there-
fore, we have no idea of lamp life for required output. The
capacitor bank charge time for maximum possible output is around
20 seconds. Although capacitors are fully charged,. full impulse
is not always seen at the lamp. Insulation faults in the wiring
and connectors are suspect, but are normally difficult to detect
because they lack visible effects and losses are intermittent.
We are replacing some capacitors in one laser power supply to
eliminate large leakage currents seen in several units, preventing
full charge from being obtained. The above problems, as well as
completion of laser retical drive are being worked on and are ex-
pected to be improved in March.
ENCODER - COUNTER SUBSYSTEM
The switch assembly and debugging is complete with all
counters and encoders operating properly. Final cabinet is ex-
pected in March and may be received for shipment with system.
System tests have to be completed when system debugging is under-
way.
