Fluoride-Fiber Window Margin

Compare a thulium-fluoride operating wavelength with caller-supplied transmission-window bounds.

Description

A fluoride-fiber wavelength screen uses caller-supplied transmission-window endpoints.

A fluoride-fiber wavelength screen uses caller-supplied transmission-window endpoints. Edge margins identify which bound is exceeded.^[1]

Compare a thulium-fluoride operating wavelength with caller-supplied transmission-window bounds.

When to use Fluoride-Fiber Window Margin

Use this tool to compare a thulium-fluoride operating wavelength with caller-supplied transmission-window bounds.

Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.

How to use Fluoride-Fiber Window Margin and understand its results

Prepare the optical measurements, geometry, fitted coefficients or caller-selected thresholds requested. Confirm wavelength, radius/diameter, pulse-width, angle and unit conventions before running the calculation.
Enter operatingWavelengthNanometers, minimumWindowNanometers, maximumWindowNanometers using the field table and calculation rules, then run the tool.
Read lowerMarginNanometers, upperMarginNanometers, withinWindow. The explanation below defines the units, signs, ordering and any flags or placeholder values.
If the tool reports an input issue, correct the values and run it again. Apply the stated assumptions when interpreting a successfully returned result.

Input field	Meaning	Value type; see rules below	Requirement
operatingWavelengthNanometers	Operating wavelength (nm)	number; minimum: 0	Required
minimumWindowNanometers	Minimum transmission-window wavelength (nm)	number; minimum: 0	Required
maximumWindowNanometers	Maximum transmission-window wavelength (nm)	number; minimum: 0	Required

Enter nonnegative wavelengths with ordered bounds. Return margins and inclusive within-window flag; equal bounds admit only that wavelength.

lowerMargin=operating−minimum; upperMargin=maximum−operating

Units, indexing, boundary conditions and exceptional cases are defined in the calculation rules above.

Output field	Meaning	Value type
lowerMarginNanometers	Lower-window margin (nm)	number
upperMarginNanometers	Upper-window margin (nm)	number
withinWindow	Within window	boolean

Limitations and assumptions

No material transmission spectrum, gain or attenuation threshold is embedded.

Numeric inputs must be finite. Follow the calculation-specific rules for overflow, underflow and exceptional cases. Missing required fields, extra fields, wrong value types and violations of the calculation rules are input errors. A successfully returned false flag is an evaluated outcome; its meaning is explained above.

Alternative or Complementary methods

Use HDFA Window Margin: Check a wavelength against caller-supplied holmium-fiber amplifier window bounds. For a complementary task, use TDFA Band Overlap: Calculate overlap between TDFA gain and a requested signal band.
