General Optical Measurements

From OLEG

Here we record the conventions and method to measure basic optical quantities of thin films: transmittance, reflectance, and absorption. We expressly have written this for the equipment within OLEG. ...Create at least one general figure

Transmittance

slit mount

aluminium base

• how to measure the transmittance more accurately

1. remove small slit mount and aluminium base
2. replace them with big slit mount
3. stick the substrate with a double-side tape
4. adjust the height and size of light

Reflectance

• something here

Absorption=

• bulk in film
• in solution
