Photometry Definition

Photometry is defined as the science of measuring light in terms of its perceived brightness to the human eye.

Fiber Photometry

Fiber photometry uses optical fibers and fluorescent indicators to record neural activity in living animals.

Flame Photometry

Flame photometry determines the concentration of metal ions in a sample by measuring emitted light from a flame.

Reflectance Photometry

Reflectance photometry measures the color and reflectance properties of surfaces by analyzing reflected light.
