Laser-sensing head
LSH-155/130 self-containing module consists of an aspheric lens, an angle-cut graded refractive index collimating lens and an optical isolator. The laser-sensing head couples light from semiconductor diode lasers into a singlemode fiber. It features low coupling loss from the laser-diode chip to the optical fiber and low backreflection, according to the company.
