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°.
We can produce narrow-pitch PCS (polarization conversion elements)! They can be offered as components that withstand high-temperature environments for automotive applications.
We would like to introduce the "Patterned Retarder for PCS." By combining a patterned retarder with a phase difference line and slit pattern, created using phase difference patterning technology for optical alignment materials, with a PBS array, it is possible to produce a polarization conversion element that efficiently generates polarized light from natural light. Please feel free to contact us when you need assistance. 【Features】 ■ Unlike conventional film-based products, it has no unevenness and can be directly attached to the PBS array, allowing for the production of a narrower pitch PCS (polarization conversion element) than before. ■ It can be provided as a device that withstands high-temperature environments for automotive applications. *For more details, please download the PDF or feel free to contact us.
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.
