Fee Schedule for Windowless Si Photodiodes

 

Silicon (Si) photodiodes are available from NIST as transfer standard detectors in the vacuum ultraviolet spectral region. These Si devices are calibrated in the wavelength range from 5 nm to 254 nm only, but will respond to radiation from the x-ray region (response falls off at photon energies above ~10 keV) to the Si bandgap at 1.1 µm wavelength. These devices can be calibrated at wavelengths between 254 nm and the Si bandgap by NIST's Optical Technology Division.

In addition to these Si detectors, the Vacuum UV Transfer Standard Program issues other types of transfer standard detectors:

The fee sheet for all detector types is available as a PDF file.

Inquiries and orders should be directed to Rob Vest.

Photodiodes being returned to NIST for recalibration must be removed from user fixtures prior to shipment to NIST.

U.S. Orders: Fees are FOB destination (UPS ground). Terms are net 30.

Foreign Orders: It is NIST policy that orders originating from outside the U.S. be paid in advance. The NIST Calibration Program provides information about and makes arrangements for prepayment. Foreign orders will be shipped via air freight. Customs duties are the responsibility of the customer.
