optical high pass filter
optical high pass filter
Optical High Pass Filter is an optical filter that transmits high-frequency (shorter wavelength) light and absorbs low-frequency (longer wavelength) light. It is particularly suitable for the detection or removal of undesired low-frequency signals.
Our optical high pass filter is perfect for simulating a camera lens that has a high sensitivity or low f-number. Like our other optical high-pass filter, this one will remove unnecessary noise from your video footage by simply filtering out the frequency below a certain threshold. The filter features an IR cut glass and is compatible to work with almost all major DSLR cameras and camcorders.
This optical high-pass filter is a light-sensitive transparent plate that uses electrostatic charging to form lines of high density. The charge of the high-density line acts as a mask to block ambient light and reveal the image while allowing the laser beam to pass through.
We are a customized fiber optic polishing film factory in China. If you need optical high-pass filters, welcome to contact us
Medical Detection Filter
We are a narrow bandpass optical filters limited company in China. The coating of our biochemical filter is ion-assisted. It can ensure that the filter has a high transmittance and a cut-off depth above OD4 while controlling the bandwidth tolerance to ± 2nm. The unique coating processing makes the biochemical filter wavelength accurate and durable. If you need this filter, welcome to contact us.
