(1) Confidence level of 3σ (≥99.6%) and traceable to accepted physical standards.
(2) Standard deviation for a 5 minute measurement period after the instrument has reached thermal equilibrium.
(3) Wavelength resolution is approximately two times repeatability.
(4) Data in units of nm, µm, and cm
-1
are given as vacuum values.
(5) The IR / MIR versions do not measure absolute power. An intensity meter displays relative power.
(6) Bandwidth is FWHM. When bandwidth is greater, wavelength accuracy is reduced.
(7) Characteristic performance, but non-warranted.
(8) For 621B-VIS and 621B-NIR, required input power is about half of values given.
(9) Sensitivity at other wavelengths can be determined from graphs available upon request.
(10) IR and MIR required beam height is 5.4 ± 0.25”
(11) IR and MIR instrument height is adjustable (7.25 ± 0.25”) for alignment purposes.
