Fee Schedule for Windowed CsTe Photodiodes
Cesium
Telluride (CsTe) photodiodes are available from
NIST as transfer standard detectors in the vacuum ultraviolet spectral region.
CsTe devices are calibrated in the wavelength range from 116 nm to
254 nm only. At shorter wavelengths, the window is opaque. There is no
significant photoemission yield at wavelengths longer than 300 nm or
400 nm. (The exact cutoff depends on the Cs and Te stochiometry and
varies among devices.) These devices can be calibrated at wavelengths between
254 nm and the photoemission cutoff by NIST's
Optical Technology Division.
In addition to these CsTe detectors, the
Vacuum UV
Transfer Standard Program issues other types of transfer standard detectors:
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.
