2D Mode Solver Software

Multi Mode, Step Index; 650 nm; Core Diameter 240-2,980 µm; Cladding Diameter 250-3,000 µm; Coating PE, PVC, Polyamide, PP, None; Numerical Aperture 0.46-0.58 Toray Industries' plastic optical fiber products, RAYTELA™, boast highly reliable transmission with low attenuation and excellent noise-resistant characteristics. RAYTELA is a multi mode, step index optical fiber with low loss and high reliability. Compared to optical fibers with cores made of silica or composite glass, plastic optical fibers (POF) are entirely made of polymer materials. Not only coatings and jackets, but also fiber core and cladding consist of polymers. While showing higher attenuation and lower transmission capacity, plastic optical fibers are less brittle, lightweight, more flexible, easier to handle and very cost-effective. The polymethyl methacrylate (PMMA) that makes up the core portion of the RAYTELA fiber uses a clean polymer made with integrated manufacturing from monomer through to fiber production. A special fluorine containing polymer is used for the cladding. Plastic optical fiber cords, curl cords or cables with PE, PVC, or PP jacket are also available. The cable diameter ranges between 5 and 6 mm. These lines have good resistance to heat, physical determination and chemicals. Furthermore, light guides with up to 64 fibers, bundled and jacketed for a temperature range up to +105°C are available. They are suitable for light sources of medical devices and display lighting for art objects among others. The portfolio comprises also plastic optical fiber cords for broadband communications and high NA fibers.

Actively Q-switched DPSS laser; pulse width <2 ns; repetition rate up to 50 kHz; very low jitter; 1064 nm and harmonics down to 355 nm Utilising advanced technology, SPOT actively Q-switched DPSS lasers provide a short pulse output (pulse widths <2 ns) at repetition rates from single shot up to >50 kHz with very low jitter. The series features fundamental YAG wavelength at 1064 nm and harmonics down to 355 nm. The compact design enables the lasers to be easily integrated into scientific instrumentation. Applications include laser induced fluorescence, time resolved fluorescence, micromachining, biotechnology, plasma generation, remote sensing, photo acoustic imaging, MALDI mass spectrometry and MALDI imaging. SPOT laser systems consist of a laser head with a separate power supply unit. Both units are connected with a cable which is hard wired into the laser head while having a 37 way ‘D’ connector for connection to the power supply unit. The SPOT DPSS laser series feature simple, user-friendly control with the minimum of user defined parameters. The systems are designed as fixed power level devices under automatic operation, or power can be varied by adjusting the pump diode current via RS232 interface.
