The NK-202 electric collimator is suitable for 150kV tube voltage, vehicle-mounted, DR digital and ordinary X-ray diagnostic equipment. The X-ray field is rectangular.This product conforms to the relevant national and industrial standards, with small size, high reliability, high cost performance characteristics.
A NK-202 electric collimator is an input and output optical element of a fiber optic communication optical device. Its structure is simple — the astigmatic light from the fiber is converted into parallel light (gaussian beam) by a front convex lens.Its function is to coupling the maximum optical efficiency into the required device or to accept the maximum optical signal efficiency.
