Band-pass filter

Band-pass filter

Because of its high capacity and reliability, multi-mode optical fiber coupling laser generally is used for many fields. Because multi-mode fiber has a larger core-size, it supports more than one propagation mode; hence it is limited by modal dispersion.

The band-pass filter is a kind of optical elements which to make a specific wavelength of light to pass through, and the other wavelength of light reflection or attenuation. The work area is generally in ultraviolet light area, near infrared area and far infrared area.
