1/2 a watt or 500mw

Question 6

Would us used red light pr NIR to target deep tissues & Blood vessels?

Answer 6

NIR

Question 7

Would you used red light or NIR to target the cellular level on living tissues?

Answer 7

Red light

Question 8

would you have more or less photons pass by in 1 second with blue light, compared to red light?

Answer 8

more, due to the smaller wavelength.

Question 9

what is a chromophore?

Answer 9

the target which a photon is absorbed into. (Melanin…)

what is the best wavelength optical window for absorption by tissue chromophore’s?

Answer 10

600-1200 nm red- IR

Question 11

what is the stokes shift?

Answer 11

the slight difference between the absorbed photon energy & the released photon energy.

Answer 14

endothelial cells, keratincytes, fibroblasts macrophage and neutrophils

Question 15

what positive effects does LLLT have (4)

Answer 15

decreases cell death, increases cell migration, increases cell adhesion & increases cell proliferation
