LD 8900 Goniometric Radiometer
For Characterizing Laser Diodes, LEDs, VCSELs and Fiber Optics.
Photon's LD 8900 Goniometric Radiometer for characterizing the angular radiation intensity of light provides direct real-time far-field measurements with 24 dB dynamic range, angular sampling of 0.055° and a field-of-view of &plusmin;72° (144°). The LD 8900 is ideal for characterizing the light flux from many light-emitting sources, including VCSELs, laser diodes, optical fibers, optical wave-guides, and more. The LD 8900 provides full three-dimensional measures of the far-field pattern in minutes or less, with better resolution than a CCD camera.
The LD 8900 is available with either a silicon detector or an InGaAs detector, and has a standard entrance aperture of 2 mm, with an optional 10-mm entrance aperture for use with large sources such as LEDs and LD bars. The LD 8900 is a modular unit designed for R&D, manufacturing, and custom applications, such as testing LDs at the wafer level, measuring optical fiber attributes. The complete system includes:
The Scan Unit
The Motion Control Module
PC (monitor is user supplied) with the Goniometric Radiometer Model GS880 Scan Control and Data Acquisition Card installed
Goniometric Radiometer Acquisition and Analysis Software for user-specified MS Windows 98 or Windows NT 4.0
Power and Instrument Cables
An optional LD 8900 semi-custom source mount, specifically designed to meet your application needs, can be quoted upon request.

The GO 40 goniometer allows an adjustment of ± 20° around a defined optical axis by means of a precision worm gear drive and adjustable dovetail guides. The distance between the mounting surface and the rotation axis of 20 mm can be used for prisms or other optics. Unintended adjustment can be avoided by using a fixing screw. In order to integrate the SYS 65 system, the adapter plate ADP 65B or slide RT 65-35-R should be used.
For motorized versions (step or DC servo motor) see chapter Motorized Positioning Systems in the catalog.
- adjustable dovetail guides
- mountable on slide and adapter plate
- deformation-resistant aluminium alloy, black anodized

What is a goniometer? A goniometer stage (sometimes called a goniometer table) is a tilting stage that rotates about a virtual axis fixed in space above the stage surface. Zaber's LMG Series motorized goniometers are stepper motor driven positioning goniometers designed to interface with our T-CD series Stepper Motor Controller offering high resolution daisy-chainable operation. The LMG60 tilting goniometer stages pictured above are crossed roller bearing goniometers with a virtual axis of rotation 60mm above the goniometer stage surface respectively. The goniometer stage is 20mm high.

Traditional angular contact ball bearing measuring devices still use manual or semi-manual machines: a low degree of precision is obtained and the process time is long. The Bussi contact angle measuring machine is extremely precise, reliable, fully automatic and fast. It combines electronics with top-level engineering and pneumatics. It features:
Data setting: a computer stores the bearing data it is necessary to measure and is input just once. Every time there is a type changeover, only the bearing code needs to be recalled, thereby avoiding error and time wasting. Storage capacity: 500 types of bearing.
Automatic measurement: it makes two checks simultaneously, the contact angle measure and that all the balls are present. Field of measurement: 0° to 89.9°
Precision and repeatability: precise to ± 0.2 ° with high measurement repeatability. This performance can depend on the level of precision achieved when the bearing is constructed.
Measurement speed: the process is extremely quick, between 14 and 17 sec, with a capacity of up to 257 pieces/hr. Maximum type changeover: < 4 min
Optional automation for lines
