What is typical application for 710nm Shortpass Filters?

A 710nm shortpass filter is a professional optical element that transmits light with wavelengths shorter than 710nm while blocking near-infrared light with longer wavelengths.

710nm Shortpass Filters find extensive application across various fields:

Imaging and machine vision: eliminates infrared stray light to ensure the light received by the sensor matches what the human eye sees, thereby improving imaging clarity and color reproduction accuracy.
Scientific research and spectral analysis: used in research fields that require precise separation of different spectral bands, including fluorescence excitation spectroscopy and Raman spectroscopy.
Security surveillance: serves as a core component in day/night cameras. During daytime, it switches in to block infrared light, ensuring the CMOS/CCD sensor captures clear, undistorted color images without color deviation.

What is key parameter when choose for Shortpass Filters?

When selecting a shortpass filter, the key parameter to consider include:

Cut-off Wavelength: This is the most critical selection criterion, typically defined as the wavelength at which the transmittance drops to 50%.

Transmission in Passband: The percentage of optical energy that passes through the filter within the allowed wavelength band.

Optical Density(OD): A measure of the filter’s ability to block unwanted long-wavelength light, commonly expressed as optical density. A higher OD value indicates more effective blocking.

Edge Slope: The spectral width of the transition from high transmission to high blocking. A smaller value means a steeper, sharper edge.

Angle of Incidence (AOI): The optical performance of the filter changes with the angle of incident light. As the AOI increases, the cut-off wavelength shifts toward shorter wavelengths.

Physical Properties and Environmental Durability: Includes substrate material, surface quality, dimensions, as well as operating temperature range and humidity tolerance.
