Definition of IR Cut Filter

IR-cut filter(ICF) is a short pass (or called a lowpass filter) filter that blocks infrared light and transmits the visible range light(400~700nm).

The short pass filter is to transmit shorter wavelengths of light while rejecting longer wavelengths. The design of this type of filter makes it easier to separate excitation and emission wavelengths within the desired range, effectively isolating longer wavelength light without interfering with specific wavelengths.

Features of Short Pass Filter
High Transmittance: short wave pass filter have high transmittance and high cut-off depth, with transmittance typically reaching over 90%.

High Cut-off Steepness: These filters have a narrow cut-off bandwidth and high cut-off steepness, effectively separating excitation and emission wavelengths without interfering with the wavelengths of interest.

High Background Light Density: They possess a high background light density, effectively reducing background light interference.

Material Diversity: Short pass filter can be made from materials such as UV fused silica or optical-grade float glass, offering different transmission characteristics and cut-off wavelengths.

Application Fields of shortpass filter
Fluorescence Excitation Spectroscopy: Used to eliminate interference light outside the usable wavelength band, improving imaging clarity and system sensitivity.

Raman Spectroscopy Applications: Crucial for noise reduction in spectra and isolating specific spectral regions.
