Definition of Long/Short Pass Filter

A filter that lets appointed wavelength pass and block lower wavelength,we called it long pass or high pass filter.Such as IR pass filter is a long pass filter.

A filter that lets appointed wavelength pass and block higher wavelength,we called it short pass or low pass filter.Such as IR cut filter is a short pass filter.
