Thorlabs
The Thorlabs CAL-UVPD is the manufacturer recalibration service specifically designated for the S120VC UV-Extended Silicon Photodiode Power Sensor, featuring an initial release date of February 2, 2021. This service applies to the specified item number and serial number based on current manufacturer documentation and available lead times. Submit a request for quote with the exact part number, serial number, and quantity to initiate the recalibration process.
Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Thorlabs references — within one business day.
For a faster response, include quantity, condition, and delivery destination.
