A 710nm IR Cut-Off Optical Shortpass Filter is designed to transmit visible light while effectively blocking infrared (IR) wavelengths beyond 710 nanometers (nm). This filter is ideal for optical systems requiring precise separation between visible and infrared light, ensuring that only visible light below 710 nm passes through, while infrared radiation is cut off.

Key features of the 710nm IR Cut-Off Shortpass Filter:

• Cut-Off Wavelength: 710 nm – The filter sharply blocks IR wavelengths beyond 710 nm, allowing only visible light below this threshold to pass.
• Transmission Range: High transmission of visible light from the ultraviolet through to the red spectrum (up to 710 nm), maintaining brightness and clarity for visible light applications.
• Blocking Range: Efficient attenuation of infrared wavelengths greater than 710 nm, preventing IR interference in the optical system.
• Sharp Transition: Exhibits a steep transition from the transmission of visible light to the blocking of IR light, ensuring precise cutoff at 710 nm.
• Durable Coating: Typically features advanced optical coatings, such as anti-reflective or dielectric coatings, to enhance the filter’s performance, longevity, and resistance to environmental factors like scratching or humidity.

Applications:

• Imaging and Photography: Improves color accuracy by blocking IR light, which can distort color balance or cause glare in images.
• Cameras and Sensors: Prevents IR light from reaching the sensor, ensuring better image quality and color fidelity in various lighting conditions.
• Machine Vision Systems: Enhances detection accuracy by cutting off IR light, which can interfere with machine vision cameras and sensors used for automation and quality control.
• Optical Instruments: Used in applications where precise light filtering is needed to exclude IR, such as in microscopy or laser systems.
