(1) Performance guaranteed on the 700 – 1000 nm range.
(2) T° calibrated on 16-30°C. For quality check, an absolute accuracy calibration procedure is available with SpectraResolver. Not frequently required.
(3) Warm-up: best performances are achieved under steady state conditions, typically ambient temperature stable at +/- 0.5°C per hour maximum, constant air flow, LW-10 running for more than 30 minutes. No sensitivity to air pressure variation.
(4) According to 3σ criterion.
(5) Computational speed. Depending on PC hardware and settings.
(6) Coupled in Polarization Maintaining singlemode fiber.
