Spare Calibration Module, Photodiode Sensors

Order 818-SCAL-OPT when you need to order a spare calibration module only, for 818 Series photodiode detectors, without recalibration of the detector. For example, order this part when you want to upgrade 818-XX to 818-XX/DB, or 818-XX/CM to 818-XX/DB or vice versa, or when the calibration module is lost or broken. The order requires the following information at the time of order, to be able to identify the correct calibration file:

1. the required calibration module type:

• Round 8-pin DIN connector
• DB15 D-shaped connector

2. the detector model:

• 818-SL series
• 818-ST series
• 818-IR series
• 818-UV series
• 818-IG series
• 818-ST-UV series
• 818-SL-L series
• 818-IR-L series
• 818-UV-L series
• 818-IG-L series
• 818-ST2 series
• 818-ST2-UV series
• 818-ST2-IR series
• 819C/D-IG series
• 819C/D-SL series
• 918C/D-UV series

3. the serial number.

We recommend that optical power meters and detectors be calibrated every 12 months to ensure NIST traceability.
