Fields of application of Bandpass Optical Filters products

Aug 19,2022

SIZE

Bandpass Optical Filters products are narrow-bandwidth optical devices that allow specific wavelengths of light to pass, cut off or reflect other short-wave and long-wave wavelengths. Bandpass Optical Filters products are used in a wide variety of fields including clinical medicine, environmental experiments, colorimetric analysis, elemental and laser line separation, flame photometry, fluorescence and immunoassays. In addition, bandpass interference filters can be used to select discrete spectral lines from scattered lines from arc or gas discharge lamps and to separate out specific spectral lines from Ar, Kr, Nd:YAG and other lasers. They are often used in conjunction with laser diode modules and LEDs. Different bandwidths can be selected according to customer needs.

Application areas of Bandpass Optical Filters products:

Cable TV upgrade equipment, wireless transmission equipment, mobile phone barcode scanning, infrared electronic whiteboard, infrared camera, infrared touch screen, iris recognition, infrared medical equipment, infrared ink recognition, red film recognition, face recognition sensor system. Handheld infrared laser rangefinders, optical instruments, medical and health equipment and testing instruments.

Bandpass Optical Filters products are made by adding special dyes or evaporating a layer of optical film on the surface of plastic or glass substrates to attenuate (absorb) certain wavelengths of light waves or precisely select a small range of wavelengths to pass, while reflecting (or absorption) other unwanted bands. By changing the structure of the filter and the optical parameters of the film, various spectral properties can be obtained, so that the filter can control, adjust and change the transmission, reflection, polarization or phase state of light waves.
