Photoelastic light modulators

Photoelastic modulators (PEMs) are a key component across a diverse range of photonic applications.

Our portfolio of Photoelastic Modulators (PEMs) offers advanced solutions for manipulating the polarisation state of light at frequencies ranging from 20 to 100 kHz. Utilising the photoelastic effect, these components effectively modify the birefringence of optical elements.

Our PEMs are widely deployed across diverse and demanding applications in optical polarisation measurement. Whether for astronomical studies, optical lithography, thin film analysis, or fibre optic metrology, our PEM systems provide precise and reliable performance to meet complex optical polarisation challenges.
