The monolithic collimator produces, from the light of a single emitter, a symmetrical beam with an almost round far-field profile. The collimator consists of a monolithic glass block with two opposite crossed cylindrical surfaces having different focal lengths, which collimate the light from the fast and slow axes. This optical component is suitable for light collimation of single emitters in the blue spectral range.
Applications for collimators:
- collimation of high-power diode lasers
- fiber coupling
