Name: High Speed Variabler Retarder
Availability: InStock

The High Speed Variable Retarder from Meadowlark Optics combines state-of-the-art liquid crystal technology with lightning-fast switching times. This sophisticated device offers sub-millisecond switching times and enables precise control of polarization states, making it perfect for applications in photonics, optics and advanced research. Thanks to the innovative control of nematic liquid crystals, the birefringence can be flexibly adjusted, allowing the creation of various polarization modes such as linear, elliptical and circular.

Fast switching times for demanding applications

The High Speed Variable Retarder impresses with its exceptional speed and efficiency. When the device switches from low to high (λ/2 to 0), it only needs 50 µs at a wavelength of 532 nm. And when switching from high to low (0 to λ/2), it is just as fast at only about 500 µs. Thanks to this enormous speed, you can control even sophisticated optical systems precisely and reliably. This is why the fast variable retarder ideal for applications requiring high-speed polarization controls.

Precise optics and high-quality materials

The retarder is made of synthetic quartz glass and is equipped with an advanced indium tin oxide (ITO) coating. This provides the highest light transmission in the range of 450 to 700 nmWith a low surface reflection of ≤ 0.5 % and a distortion of the transmitted wavefront of maximum λ/4 at 632.8 nm, it meets the highest precision requirements.

Easy integration through integrated driver

The D5020-HS driver allows the High Speed Variable Retarder to be easily integrated into existing systems. It offers four operating modes, including Chop, Gate and steady state, as well as the control of up to two retarder cells simultaneously. The USB interface enables easy control, which makes the retarder particularly user-friendly.

Robust and versatile

The device is designed for demanding applications. It can withstand temperatures up to 50 °C and a load of 500 W/cm² CW The robust construction and precise workmanship ensure a long service life and reliability.

The High Speed Variable Retarder from Meadowlark Optics is the perfect choice for anyone who needs precise and fast polarization control. Whether in research, development or industrial applications – this fast-switching polarization modulator sets new standards.
