Optical test equipment or optical measuring instruments are used to measure and characterize the physical properties of light. The insatiable demand for higher capacity in communication networks has fueled the need for highly precise optical test solutions.

Array connector test harness for single-ended optical test instruments

InactiveUS20130301036A1Simple methodMaterial analysis by optical meansElectromagnetic transmissionFiberOptical test

A system, apparatus and method for testing optical fiber systems by providing a near-end and far-end harness that loops the set of fibers in the fiber system together. The near-end harness has an interface to connect to the tester. The tester then effects testing on the entire set of fibers, which are looped together by the configuration of the two harnesses creating a single optical path that traverses the entire set or subset of fibers in the network, so a launched test signal propagates through the entire set of looped fibers, providing measurement results for the fibers.

Thermal-optical test calibrating device

InactiveCN105865756AOptical axis determinationLens position determinationOptical testComputational physics

The invention relates to a calibrating device for space thermal-optical testing. The device can be used for detecting a defocusing amount of a parallel light tube with a large calibre in a thermal-optical test and belongs to the field of photoelectric detection. Aiming at the problems that the defocusing of the parallel light tube causes that the detection precision is reduced and system errors are increased when an optical remote sensor is used for carrying out the thermal-optical test, the invention designs the thermal-optical test calibrating device, which can detect the defocusing amount of the parallel light tube in real time. The thermal-optical test calibrating device is small in optical shielding, high in detection precision, good in instantaneity and good in reliability and has very high practicability.
