Formula Used

Corrected measured value = (Measured value + Bias correction) × Scale factor.

Signed error = Corrected measured value − Expected value.

Absolute error = |Signed error|.

Percent error = |Signed error ÷ Expected value| × 100.

Combined uncertainty = √(Reference uncertainty² + Measured uncertainty²).

Standard error = Combined uncertainty ÷ √Sample size.

Z score = Signed error ÷ Standard error.

Confidence interval = Signed error ± Critical z value × Standard error.

Effective tolerance = max(|Expected value| × Tolerance percent ÷ 100, Absolute tolerance).

Suggested raw adjustment = Expected value ÷ Scale factor − Bias correction − Measured value.

OptiSystem Component Error Analysis

OptiSystem projects often contain many linked components. A small input mismatch can move the final optical result. This calculator checks one component at a time. It compares the target value with the measured value. It also studies uncertainty, tolerance, and sample size. The goal is not only to show an error. The goal is to explain whether that error is important.

Why Component Error Happens

Component error can appear for many reasons. A laser may use the wrong power unit. A filter may have an incorrect bandwidth. A detector may use a changed responsivity value. Simulation blocks can also inherit old parameters. When a project is copied, hidden values may remain inside a component. These small issues create output differences. Statistical checks make those differences easier to review.

What This Tool Measures

The calculator finds signed error, absolute error, percent error, relative error, standard error, and a confidence interval. It also checks the selected tolerance limit. The tolerance test gives a quick pass or review message. The z score helps show whether the observed difference is large compared with combined uncertainty. A weighted error is included for cases where one component affects the design more than others.

Best Use In Optical Workflows

Use this tool after changing a component parameter. Enter the expected value from your design sheet. Then enter the simulated or measured output. Keep units consistent. Use watts, dBm, nanometers, hertz, or another unit, but do not mix units. If uncertainty is unknown, start with a small estimate. Increase it when measurements are noisy.

Reading The Result

A low percent error means the component is close to target. A high z score means the difference is strong relative to uncertainty. A failed tolerance check means the component needs review. Check the component settings, linked variables, and unit conversions. Export the report for records. The CSV file is useful for spreadsheets. The PDF file is useful for project notes and audit logs.

Maintenance Tips

Review each export after major design edits. Store baseline values before tuning. Compare related components in the same unit system. Repeat the check when sample size changes. This habit keeps reports consistent and reduces avoidable simulation mistakes during final project checks.

FAQs

What does this calculator fix?

It does not edit your OptiSystem file. It identifies possible calculation errors, tolerance failures, uncertainty issues, and correction values. You can then update the component settings manually.

Which value should I use as expected value?

Use the design target, datasheet value, lab reference, or accepted baseline value. It should use the same unit as the measured value.

Why should I enter uncertainty?

Uncertainty shows how much variation may exist in the reference and measured values. It helps calculate standard error, z score, and confidence interval.

How is the tolerance status decided?

The tool compares absolute error with the effective tolerance. Effective tolerance is the larger value from percent tolerance and absolute tolerance.

What happens if expected value is zero?

Percent error and relative error become unavailable. Use absolute error and absolute tolerance for zero expected values.

Can I use dBm values?

Yes, but keep all related values in dBm. Do not mix dBm with watts unless you convert the values before entry.

What does the z score show?

The z score compares signed error with standard error. A larger magnitude means the difference is large relative to combined uncertainty.

Why use CSV and PDF exports?

CSV helps with spreadsheet review and batch records. PDF gives a simple report for project notes, checks, and documentation.
