Fiber Optic Quality Tests Zisis Papandreou SPARRO Group, Regina Hall D Collaboration Meeting Bloomington, Indiana November 1 st, 2001

Thousands of km… BCAL: a few kilo-km of fibers Quality control along length of spools Method: – Quick, stable, reliable, reproducible – Optical source – Dedicated spectrometer & DAQ – Light transmission, attenuation, timing – Cross-check with ionization source

Ocean Optics Inc. Consulted with Gamble Technologies Issues for the SciFi quality control tests: – Spectrometer(s) – Light source(s) – ADC – Mounts and connectors; reproducibility – Portability – Cost

Spectrometer Option A USB-2000 – Plug and play – Single channel – Small footprint – Accessories Gratings, filters, slits – No power source – OOIBase32 (free) – calibration coeff.

Spectrometer Option B SD-1000 – Dual channel – Small footprint – Accessories Gratings, filters, slits – No power source – 2048 CCD array – Uses ADC1000USB

Light Source LS450 – Stand alone or USB – White LED – nm

Accesories #3 Grating – nm Order sorting filter – OFLV Slit – 50  m Mount – Dremel chuck holder – Custom made Connectors – SMA 905 ADC

Regina: Option B Spectrometer: SD1000 configured Light source: LS-450 with suitable LED’s Bifurcated fiber Two P200-US/VIS fibers (to SD and LS) SMA connectors and mounts OOIBase32 software (free) Reproducible, stable, bulky, assembly line tests

Option A Spectrometer: USB1000 Light source: LS-450 with suitable LED’s Two P200-US/VIS fibers (to SD and LS) SMA connectors and mounts OOIBase32 software (free) Reproducible ??, stable, portable, geared for smaller number of fibers
