Infraredlens

Conventional charge-coupled device (CCD) and complimentary metal oxide semiconductor (CMOS) sensors can exhibit near-infrared (IR) sensitivity from 700 nm to approximately 1,100 nm and can be converted to an inexpensive infrared (IR) imager with the use of a near-IR bandpass filter.

Working in the near-IR can result in greatly improved contrast depending on the characteristics of the item under inspection. Information captured in near-IR images can be significantly different than those images captured with white light based on the absorption and reflection properties of the items being inspected. It’s usually impossible to tell how an image will appear in the near-IR without experimenting. Most digital cameras have excellent near-IR sensitivity, and these tests can be performed quickly and easily by placing a visible blocking/IR pass filter over the camera lens in conjunction with a broad spectrum light source or sunlight.

MidOpt IR bandpass filters are matched to the output wavelength of infrared light-emitting diode (LED) and laser diode (LD) illumination. In the presence of normal daylight conditions, the desired contrasting effect is often lost without the use of visible blocking near-IR pass filters.
