BTS(Beam Transformation System)
A lens that converts the uneven far-field beam profile emitted from each emitter of the diode laser bar into a uniform BPP (Beam Parameter Product). Composed of a lens array for rotating the FAC lens by 90°.
Polarization conversion element
High-efficiency polarization conversion element born from thin film manufacturing technology and precision glass processing. 【What is a polarization conversion element?】 Typically, it is possible to select only specific polarization from unpolarized light using a PBS, but since the unwanted polarization components cannot be utilized, the light intensity decreases. Therefore, the polarization exchange element converts the separated unwanted polarization into the necessary polarization to improve utilization efficiency. ● For other functions and details, please download the catalog.
