Autocorrelators
Opticala Autocorrelators are devices for measuring the intensity or field autocorrelation function of light, mostly used for determining the pulse width of picosecond or femtosecond pulses, to which an electronic apparatus such as oscillascope would be too slow. The basic principle of operation of an autocorrelator for a pulse width measurement is to check the correlation of the temporal pulse trace with itself.

Bench-Top Type ASE Light Source
ASE(Amplified Spontaneous Emission) light sources are low-coherent light sources ,which combines the both features of high intensity like laser and broad spectrum like LED. Output stability is greater than those of LD and LED, and therefore they are suitable for high accuracy measurement applications. With the use of rare-earth-doped fluoride fibers, the plentiful lineup of FiberLabs light sources includes the 540 nm-, 850 nm-, 1300 nm-, 1480 nm- and SCL-bands that other companies do not provide.They are the best light sources for FBG sensors, OCT, fiber optic gyroscopes, gas sensors, and fluorescence excitation, as well as for measurement of optical components. The bench-top type is easy to use as a stand-alone light source and the modular type is convenient for integration into equipments.

Endoscopes
Originally designed for the medical sector, endoscopes are the ideal tool for inspection and maintenance today. Endoscopes offer new perspectives to viewing the insides of machines. Thanks to their flexible fibre optic cables and light weight enclosure, these extraordinary endoscopes are the ideal tool for inspection and maintenance. Endoscopes can locate problems and conflicts of the system very easily and quickly, allowing for preventative measures to be taken without the need to dismantle the machinery first. Complex dismantling of machines is usually very time and cost intensive. With the help of endoscopes, inspections in an industrial sector can therefore be organized considerably faster, more aimed and more cost-efficiently Endoscopes are used mainly by electricians, security personnel, specialists in the professional sector, and mechanics of all types. All of our endoscopes are ***Not for medical use***
