Products > Optics Test Equipment > Software for upgrading of visual autocollimators - CROSSDETECT

Small investment-big effort: CROSSDETECT serves for the upgrade of all kind of visual autocollimators, which can be equipped with a CCD-camera. The image evaluation software increases the accuracy by factor 10 compared to visual evaluation. The perfect solution for quality assurance in optics manufacture, adjustment of beams and optical components!

CROSSDETECT is an image processing system, which was developed in particular for the use in connection with autocollimators. It serves for the increase of accuracy and automation of angle measurements and offers numerous additional measuring and service functions.

CROSSDETECT can be adapted to each visual autocollimator by use of an eyepiece adapter. Using this software, the accuracy of a visual autocollimator can be increased at least by factor 10 compared with visual measurement.


data acquistion with digital USB 2.0-camera or with analogue video camera

1,3 megapixel resolution (standard, other resolutions on inquiry)

Resolution of angle measurement ‹0.1 arcsec (depending from the focal length and free aperture)

focal length range 90mm to 1100mm

free aperture 28mm or 50mm

Representation of the measuring signal as live video on the laptop monitor

additional representation of graphic hair crosses (e.g. point of reference and current hair cross position)

Representation of the measuring signal as angle value in different units

Zoom function

Measured value tables

Production and print out of freely configurable metrology records

Expenditure of the measured values over RS232 and numerous software interfaces

Announcement of tolerance fields

extensive accessories (mounting plates, basis mirror, stands, laser resolution for fast rough adjustment)

Graphic operators interface

Real time display of the current hair cross position in relation to the reference position as numerical value (reference position freely selectable)

Real time representation of the current hair cross position in relation to the reference position (reference position can set on any point)

Simultaneous real time display of hair cross position, reference position and numerical values.

Direct connection of an USB camera allows fast and high accurate data acquistion.

The graphic user surface possesses many advantages in relation to visual autocollimators. It makes fatigue-free working possible and offers different representation possibilities.

The software offers numerous functions for the use in optical applications (cementing, deflection angle, wedge angle in the transmitted light/reflection).

For the measurement of straightness and flatness the software offers a direct interface via clipboard to the proven software ELCOLEVEL.

One possible application of CROSSDETECT is the use as high accurate wedge angle measuring system for planparallel plates or wedges.
