7. Save the calibration. This panel allows you to set the collection type and area used in the
irradiance calibration. Select the appropriate type of collection and enter the associated value (if
applicable). If you choose Use Integrating Sphere, the collection area will automatically be set to
1. Click Save to File to save the calibration specifications for future use. The calibration
information will be saved in a .cal file.
Color Wizard
With OceanView, you can calculate and report the Color Rendering Index (CRI) and Correlated Color
Temperature (CCT) for your samples. OceanView will compute all color measurements except RGB.
• Emissive color measurements – Require a spectrometer, which has been calibrated to take
irradiance readings (either relative or absolute). OceanView gives you the option of choosing to
measure either emissive or reflective color from either absolute or relative irradiance.
• Reflective color measurements – Do not require an irradiance calibration, but they do require a
reference spectrum. This reference scan is taken with the same optical configuration, except a
perfect reflector is placed at the same location as the samples.

Procedure
1. Invoke the Color wizard by clicking the Create new spectroscopy application icon
.
2. Select Color.
3. In the Color Source panel, select the processing method used to calculate color data. By
choosing any of the first three options, the wizard will guide you through the steps associated
with your choice before being brought back to complete the color wizard. If there is a suitable
existing process that has already been completed, this will be available to select under the last
option, Existing processing. Select the desired process and click Next. Note that Correlated
Color Temperature (CCT) and Color Rendering Index (CRI) will not be available if you choose a
Percent Reflection as your processed data source.
4. In the Color Setup panel, the Display Parameters portion allows you to choose which color
values are displayed upon completion of the wizard. All applicable values will be added to a
color table for display. Note that Correlated Color Temperature (CCT) and Color Rendering
Index (CRI) will not be available if you chose Percent Reflection as your processed data source.
Photometry Wizard
This wizard enables you to take photometry measurements such as luminous flux (lumen), illuminance
(lux), and luminous intensity (candela). Photopic/Scotopic values are calculated over a 380 to 780 nm
wavelength range. Scotopic conditions are defined when the luminance is between 10-2 and 10-6 of a
candela per square meter (cd/m2). The difference between this scotopic vision (low-level condition)
compared to a photopic (high-level condition) affects the calculations for luminous flux (lumen),
illuminance (lux), and luminous intensity (candela) by using the V’(
) scotopic luminosity
function instead of the V(
) photopic luminosity function.
