Collection: 808nm Bandpass Filter
808nm light is a type of infrared radiation, invisible to the human eye. It's particularly interesting for its applications in various fields, including:
- Laser Hair Removal: 808nm lasers are widely used for hair removal treatments. The pigment in hair follicles absorbs this wavelength, heating and destroying them.
- Medical Therapy: It's used in certain medical procedures like photodynamic therapy (PDT) to treat conditions like cancer and acne.
- Industrial Applications: 808nm lasers can be used for cutting, welding, and marking materials.
- Remote Sensing: This wavelength is useful for remote sensing applications, such as measuring temperature and humidity.
Characteristics:
- Wavelength: 808 nanometers (nm)
- Type of Radiation: Infrared
- Visibility: Invisible to humans
- Absorption: Absorbed by melanin, the pigment in hair and skin.
- Penetration Depth: Can penetrate the skin to a certain depth.

Summary of 808nm Laser
Invisible: 808nm light is in the near-infrared range and is not visible to the human eye.
Moderate cost: 808nm lasers, especially diode lasers, are generally affordable compared to some other laser wavelengths. However, the cost can vary depending on factors like power output, beam quality, and additional features.
