Calculate CIE 1931 xy Coordinates from Spectral Power Distribution (SPD)
Calculate CIE 1931 xy Coordinates from Spectral Power Distribution (SPD)
This online CIE 1931 xy calculator takes a spectral power distribution (SPD) input in either 1 nm or 2 nm resolution, and calculates the CIE 1931 xy coordinates. Click on "Input SPD" to load your SPD. Several notes on the SPD input:
- For best results, copy and paste irradiance data from a spreadsheet program or plain text editor, with line breaks between each wavelength data point.
- Wavelength range is 380 - 780 nm.
- Irradiance values are in arbitrary units. The calculator will automatically normalize all values.

Laser Safety Classification Guide(IEC 60825-1:2014)
Continuous Wave (CW) Laser Safety Evaluation
- Determine that the laser output is Continuous Wave (CW).
- Select the laser class and choose the appropriate time base (refer to 4.3.e).
- Determine the Accessible Emission Limit (AEL) for the selected time base.
- Compare the measured emission level with the AEL:
- If the measured value is ≤ AEL, the laser meets the class requirements.
- If the measured value is > AEL, choose a higher class and repeat the calculations until compliance is achieved.
- If further evaluation for compliance with a lower class is needed, perform additional calculations. Otherwise, the process is complete.
Single Pulse Laser Safety Evaluation
- Determine that the laser output is a single pulse.
- Select the laser class and choose the appropriate time base.
- Determine the AEL for a single pulse (AELSingle) and the AEL based on the time base (AELS,T).
- Choose the smaller value of AELSingle and AELS,T for evaluation.
- Compare the measured emission level with the chosen AEL:
- If the measured value is ≤ AEL, the laser meets the class requirements.
- If the measured value is > AEL, choose a higher class and repeat the calculations.
- If further evaluation for compliance with a lower class is needed, perform additional calculations. Otherwise, the process is complete.
Repetitively Pulsed Laser Safety Evaluation
- Determine that the laser output is repetitively pulsed.
- Select the laser class and choose the appropriate time base.
- Determine the AEL for a single pulse (AELSingle) and the AEL based on the time base (AELS,T).
- Check if multiple pulses occur within the period Ti (refer to Table 2):
- If yes, calculate the maximum allowable number of pulses (Nmax).
- Use Note 2 to calculate the pulse train AEL (AELp,train): AELp,train = AELSingle × Cp.
- Compare the measured emission level with the smallest value among:
- AELSingle
- AELS,T
- AELp,train
- If the measured value is ≤ the smallest AEL, the laser meets the class requirements. Otherwise, choose a higher class and repeat calculations.
- If further evaluation for compliance with a lower class is needed, perform additional calculations. Otherwise, the process is complete.
Class 1M and 2M Laser Safety Evaluation
- Choose the initial class of the laser: Class 1, Class 2, Class 3R, or Class 3B.
- Select the applicable time base (refer to 4.3.e).
- Determine the AEL for the chosen class.
- Measure the laser output according to Condition 1 (see Table 10).
- Compare the measured laser output with the AEL for Condition 1:
- If the laser output is ≤ AEL, the laser meets the class requirements.
- If the laser output is > AEL, choose a higher class (e.g., Class 3B or Class 4) and repeat calculations.
- If required, check whether the laser could satisfy the AEL of a lower class and repeat calculations.
- If needed, verify whether the laser could be classified as Class 1M or Class 2M:
- Measure the laser output under Condition 3 (see Table 10) and compare with the AEL for Class 1 or Class 2.
- If the output is ≤ AEL, the laser is classified as Class 1M or Class 2M.
- If the output is > AEL for Class 1 or Class 2 but < AEL for Class 3B, the laser is also classified as Class 1M or Class 2M.
- If neither condition is met, the laser is not classified as Class 1M or Class 2M.
Note:
- AELSingle: Accessible Emission Limit for a single pulse.
- AELS,T: Accessible Emission Limit based on the chosen time base.
- AELp,train: Accessible Emission Limit for a pulse train, considering the pulse count and correction factor Cp.
- T: Time base duration.
- Nmax: Maximum number of pulses allowed within the period Ti.
