Collection: 850nm Bandpass Filter

The primary source for 850nm laser light is a semiconductor diode laser. These diodes are specifically designed to emit light at this wavelength and are fabricated using materials like gallium arsenide (GaAs) or indium phosphide (InP).

808nm: Generally has slightly deeper tissue penetration than 850nm due to its shorter wavelength. This makes it more suitable for applications requiring deeper tissue interaction.

850nm: While still capable of penetrating tissues, it may not be as effective as 808nm for very deep tissue applications.
