Q

Reflectance photometry

Darker color = ?

effect to reflected light

A

Darker color = less light reflected

17
Q

Reflectance photometry

Lighter color = ?

effect to reflected light

A

Lighter color = more light reflected

18
Q

Reflectance photometry

Familiarize the components of reflectance photometry

A
  • Monochromatic light source w/ filter
  • Light emitting diode
  • Photodetector
19
Q

20
Q

Reflectance photometry

Identify what component of reflectance photometry:

provides a specific wavelength for each test with a test pad color reaction (test pad surface)

A

Light emitting diode (LED)

21
Q

Reflectance photometry

  • Receives light coming from the photodetector
  • Compares the reflected light to a standard already embedded in the machine
A

Analog/digital converter

22
Q

Sequence of process of reflectance photometry?

A
  1. Light from LED
  2. Light to test pad surface
  3. Detection of reflection through photodetector
  4. Analogoue-digital converter receives refelction and compares to standard
  5. Goes through microprocessor
  6. Result
23
Q

Arrange the sequence of equipments for reflectance photometry:

a. Detector
b. LED
c. Microprocessor
d. Test pad surface
e. Analogue-digital converter

A

(1) LED → (2) Test pad surface → (3) Detector → (4) Analogue-digital converter → (5) Microprocessor → RESULT
