Technical Specifications
Specifications for this model are coming soon — call us for measured data.
Infrared narrowband filter, also known as infrared interference filter, infrared bandpass filter, infrared bandpass interference filter, acts on the passage of narrowband wavelengths in the infrared band and cuts off light in other bands, including visible light. Our company's infrared filter starts cutting off from the short wave ultraviolet region and can effectively eliminate noise.
