It is widely used in communication components with infrared permeability. While helping to pass infrared signals, because of the visual black, the internal structure can be easily covered. It is mainly used for infrared signal transmission or infrared windows of infrared light panels, cameras, fingerprint recognition, video phones, car license plates, CCTV photoresistors, mobile phones, computers, home appliances, automobiles, infrared touch screens, etc.
Wizard:
· Heat treatment to strengthen the absorption type neutral filter can improve its laser endurance.
· Consult the sales department for details.
reference:
· Optically neutral, also known as neutral density filter.
Note:
· The transmittance curve is the actual measured value of the sample, and may vary with manufacturing batches.
· Absorptive neutral filter, the dissolving conditions of the glass during manufacture are different, and the effect of the color agent is also different. The transmittance is adjusted by the thickness of the plate,
Therefore, the marked thickness value is for reference only.
· Transmittance refers to the average value of 400-700 nm (visible light) in the wavelength range.
· During thermal strengthening, the filter will expand. Please note that the external dimension tolerance of the heat-strengthened filter is ±0.2mm
· When checking the optical path and adjusting the optical axis, be sure to wear laser protective glasses.
