OPTICAL MEASUREMENT SYSTEM SOLUTION
【PHOTOMETRIC MODULE】 POLARIZATION MEASUREMENT MODULE PMD002/POL
PRODUCT OVERVIEW
【PHOTOMETRIC MODULE】 POLARIZATION MEASUREMENT MODULE PMD002/POL
This module is for polarization and extinction ratio measurement module of the spatial polarizer rotation method. It directly measures the polarization state of the collimated incident light. In addition, the output polarization state of optical fibers and laser diodes can be measured by using an objective lens.
Polarization measuring sensor head can be used as a single unit. Furthermore it can be used in combination with manual/semiautomatic prober system, and applicable to the polarization measurement of wafer level VCSEL.
FEATURE
- Possible to measure polarization/extinction ratio with high speed, resolution, reproducibility.
- High angle accuracy is achieved by rotation of polarizer controlled by pulse rotation stage.
- Objective lens can be attached. Spatial light measurement of fibers, various lasers, VCSEL, etc., is also possible.
- Large diameter beam can be measured. (Up to φ10 mm collimated light can be measured.)
APPLICATION
- Measurement of polarization and extinction ratio characteristic of various light emitting devices
- Laser diode, laser device, optical fiber, optical waveguide, and various optical device and module
