Optical shutter

An optical shutter controls the transmission of low-power imaging light in optical systems at high speed. It selectively blocks or allows light to pass for precise timing and exposure control. These shutters deliver continuous high-speed modulation and enhance low-power safety. Their features make them valuable applications for spectroscopy, microscopy, cameras, and imaging systems.

About Our Optical Shutters

At NM Laser Products, Inc., we offer a range of high-power laser shutters. We engineer these shutters to handle significant optical power levels from 10 watts to 300 watts. Our shutters are built to meet the exact requirements of different applications.

In optical setups, this function is important for experiments and imaging processes that demand timing accuracy within milliseconds or even microseconds. The ability to switch light on and off rapidly supports stable measurements, controlled exposures, and equipment protection.

Our optical shutters provide continuous high-speed modulation, enhancing light safety in both low-power and high-power systems. They serve a wide range of real-world applications, including:

• Spectroscopy: Controlling exposure to specific wavelengths during light analysis.
• Microscopy: Managing illumination during time-sensitive imaging.
• Ultrafast lasers: Pulse gating and beam modulation.
• Semiconductor manufacturing, for photolithography and wafer inspection.
• Quantum optics: Controlling photon emission and detection timing.
• Medical imaging: Laser scanning systems and diagnostic devices.

Optical Shutter vs. Mechanical Shutter vs. Electro-Optic Modulator

Optical shutters differ from mechanical shutters and electro-optic modulators in several ways:

• Mechanical shutters use moving parts, which limit their speed but make them ideal for cost-effective light blocking in less time-sensitive systems.
• Optical shutters operate faster and handle higher repetition rates without mechanical wear. They strike a balance between speed, precision, and durability for both research and industrial applications.
• Electro-optic modulators adjust the intensity of light using electric fields. They reach extremely high speeds but are often more complex and costly. Optical shutters offer a practical compromise between simplicity, performance, and cost efficiency.
