PrismMaster
The PrismMaster®
is the first really automatic goniometer featuring accurate
measurements of
prisms angles from 0° to 360° either in reflection or
in
transmission. It
incorporates an ultra-accurate rotary air bearing and a high precision
rotary
encoder whose cumulative error is within +/- 0.2 arcsec or +/- 0.5
arcsec.
The
PrismMaster can be used for angle measurements of any plano optics in
production
quantities with high speed and consistent accuracy:
Ø
any prism angle
Ø
polygons angle
Ø
wedge angles
Ø
90°-angle of prisms
Ø
parallelism of plane
plates
Ø
deviation angle through
wedges and prisms
Ø
pentaprisms angle
Ø
mirror tilt
GENERAL
DESCRIPTION
The
PrismMaster® is the first really automatic goniometer featuring
accurate
measurements of prisms angles from 0° to 360°either in
reflection or in
transmission. It incorporates an ultra-accurate rotary air bearing and
a high
precision rotary encoder whose cumulative error is within +/-0.5 arcsec
.
The PrismMaster
HR-Version- probably the
most accurate prism and polygon measuring instrument worldwide-features
a
cumulative error of typically 0.15arcsec.
The
system also includes an autocollimator mounted on a tiltable base.
Unlike other
goniometers which are using a visual autocollimator, the PrismMaster is
equipped
with a computerised
autocollimator
featuring a resolution of 0.01arcsec. The autocollimator image is taken
by a
high resolution CCD-sensor and further processed via frame grabber, PC
and
specific software.
The
fine rotary adjustment of the table is given by a high precision
micrometer. A
digital display provides an angle indication with a resolution of 0.36
arcsec or
0.036 arcsec in the HR-Version.
The
newest development PrismMaster-MOT
is
equipped with an ultra precision drive for fully automated measurement
of
optical components. The highly sophisticated rotation drive enables
automatic
positioning of any face of polygons or prisms with an accuracy less
than 5
arcsec. The state of the art software features automated zero
positioning,
constant or variable measurement steps, selectable rotation speed,
multiple
measurements etc.
The software provides
easy operation,
records of measurement data to a file and print out of the measurement
certificate.
