ConoScope Options & Accessories

In order to cover the wide range of displays to be measured, all ConoScope instruments can be configured with options and accessories to meet the requirements of a large number of specific tasks.

Detectors (light measuring devices, LMDs)

A fast photometric detector, based on a  photomultiplier-tube, is available for recording of fast temporal luminance variations.

For high-precision colorimetric analysis the optional CCDSpect spectroradiometer is recommended. Spectrometric measurements can be carried out via the focal plane stage for specific viewing directions.

Illumination

The ConoScope instruments can provide illumination through the lens system, either collimated beam illumination with adjustable direction of light incidence or diffuse illumination with various masks for shaping of the illumination scheme (e.g. conical, bi-conical, hemispherical with gloss-trap).

Stages

ConoStage 1 with integrated diffuse transmissive illumination for e.g. LCD cells and other transparent specimen. The DUT is in a horizontal position, the optical axis of the ConoScope is vertical.

ConoStage 2 supports the evaluation of monitors and TV-screens (in upright position) with three motorized axes for lateral scanning and adjustment of working distance.

ConoStage 3 is based on the gantry of the DMS 903 for positioning the ConoScope over large area display panels with three motorized axes for lateral scanning and adjustment of working distance.

DUT Electrical Driving

An arbitrary signal generator (ASG) allows for user defined voltage-time functions for direct driving with e.g. passive matrix multiplexing waveforms, and its multichannel versions allow for driving of active matrix structures (gate signals, data voltage, etc.). The photometric data-acquisition is synchronized with the ASG output signal timing.

A module driving interface (MDI) is available for programming of display controllers via serial, paralle and I2C interfaces.

The driving of video monitors is supported by the Video Driving Unit (VDU), a proprietary pattern generator that is integrated in the DMS Control Software. The VDU supports analog and digital RGB signals via various interfaces (DVI, LVDS, etc..

The DCI (Device Control Interface) is available for integration of a variety of third-party test pattern generators via RS232, GPIB or TCP/IP.

Temperature Control of DUT

For precise control of the temperature of the object of measurement (especially LCDs), an air-forced temperature control device has been made available for the ConoScope 80 for temperatures from -30°C to +85°C.
