Q

What form of light is most commonly used? Why?

NM parameters?

A

(red or infrared): most commonly used for pt tx due to its optimal depth of penetration
600-1300 nm
longer end of range penetrates more deeply (lowerr fq is deeper)

Q

Parameters for the use LED

A

Parameters for the use of lasers and light

LED: provide most diffuse light—large, superficial areas
Some laser and SLD (higher powered) have LED in visible range as ‘ON’ indicators
