2. Select the check boxes for the values desired.
Check Box Description
Lumen
This option displays the lumen values. A lumen is a “light watt.” Lumens are
calculated as the absolute spectral response of the human eye.
This option is only available for measurements from 380–780 nm, the
wavelength range visible to the human eye.
You can also calculate this measurement using a Scotopic standard by
selecting Scotopic with the sliding switch.
Lux
This option displays the lux values. The lux value is obtained by calculating
the lumen per square meter. Lux is also called a meter candle.
This option is only available for measurements from 380–780 nm, the
wavelength range visible to the human eye.
You can also calculate this measurement using a Scotopic standard by
selecting Scotopic with the sliding switch.
Candela
This option displays the luminous intensity of the sample, based on
international standards.
This option is only available for measurements from 380–780 nm, the
wavelength range visible to the human eye.
You can also calculate this measurement using a Scotopic standard by
selecting Scotopic with the sliding switch.
µJoule
This option displays the calculated energy of the sample in microjoules.
Specify the range of wavelengths to integrate by entering values in boxes
on the right side of the screen.
µWatt
This option displays the calculated power of the sample in microwatts.
Specify the range of wavelengths to integrate by entering values in boxes
on the right side of the screen.
µJoule/cm 2
This option displays the calculated energy per square centimeter of the
sample.
Specify the range of wavelengths to integrate by entering values in boxes
on the right side of the screen.
µWatt/cm 2
This option displays the calculated power per square centimeter of the
sample.
Specify the range of wavelengths to integrate by entering values in boxes
on the right side of the screen.
