The High-contrast optical shutters<\/strong> from Meadowlark Optics is a vibration-free alternative to mechanical shutters. This advanced liquid crystal shutter is particularly suitable for applications with polarized light. With its nematic liquid crystal configuration<\/strong> The shutter switches between two states: a state that rotates the input polarization by 90\u00b0 when no voltage is applied, and a state that leaves the polarization unchanged when 8 to 10 volts are applied. This precise switching enables flexible polarization control without mechanical movements.<\/p>\n

High-contrast optical shutter element with versatile wavelength options<\/h2>\n

The shutter is supplied with dichroic polarizers that cover the wavelength range of 450 nm to 700 nm<\/strong> This technology achieves an average contrast ratio of over 1.000:1<\/strong>, making it ideal for applications that require the highest precision in polarization control. In addition, shutters with larger apertures and wavelength coverage up to 2.1 microns<\/strong> available upon request.<\/p>\n

Lightning-fast switching times and vibration-free operation<\/strong><\/h3>\n

Thanks to the submillisecond switching times, the shutter is exceptionally fast. Switching from \u201cclosed\u201d (no light allowed through) to \u201copen\u201d takes only 5 milliseconds<\/strong>, while the change back is less than 0.4 milliseconds<\/strong> This speed makes the shutter particularly suitable for fast optical controls without mechanical parts generating movements or vibrations.<\/p>\n

High-contrast optical shutter \u2013 Robust, precise and durable<\/h3>\n

The optical components consist of synthetic quartz glass<\/strong> with a high-quality ITO coating that ensures a surface reflection of \u2264 0.5 %. With a wavefront distortion of maximum \u03bb\/2 at 632.8 nm and a surface quality of 60-40 scratch-dig<\/strong> The shutter meets the highest optical precision standards.<\/p>\n

Flexible and robust for versatile applications<\/strong><\/h2>\n

The high contrast optical shutter is not only compact but also optimized for demanding conditions. It can operate at temperatures of 0 \u00b0C to 50 \u00b0C<\/strong> and is designed for a maximum power density of 1 W\/cm\u00b2<\/strong> The robust construction ensures a long service life, even under intensive use.<\/p>\n

The High-contrast optical shutters<\/strong> from Meadowlark Optics offers an ideal solution for optical applications that require precise polarization control, fast switching times and vibration-free operation. Whether in photonics, laser technology or optical research - this device sets new standards in liquid crystal technology.<\/p>\n
