Linear Phasolver Measuringgine
The heart of the Phasolver is the driver pattern to be
Ladd down on a glass substrate and the coupler pattern
to be laid down on a parallel glass plate.
TC designed a new pattern to minimize errors and insure
achieving the 1 micron accuracy. It is a sinusoidal
pattern similar to the one used in their rotary
phasolver.
They are having troub-,la getting definitive bids for making
the patterns.
Ill make the glass blocks for substrate
make the coupler only it ich is straight ruling,
Driver pattern only, Gelatin on glass,
mired to bid the driver manufacture from
a patt ern
them a telephone quote on both the driver
and the coupler, but they cannot get a written quote
from him.
The trouble with getting the pattern work placed is
putting them behind schedules If they get the orders
placed by 1 Jan., it cc}uld be as late as 1 July before
they receive the finished driver.
This, is the pacing item and everything else is well
in hand. They are putting a lot of pressure on
getting the Driver work under way.
