STEP-45 And STEP-49 Probes: Temperature Controlled Pyroelectric Radiometers
•Datasheet: STEP-45 And STEP-49 Probes Temperature Controlled Pyroelectric Radiometers
These innovative instruments represent the ultimate in radiometric measurement stability: temperature control to 0.05° C from 20° to 30° C yields a temperature coefficient of less than 0.01% over the same temperature range. In other words - the Voltage Responsivity (Rv) of the probe is stable to 0.01% when measuring from nW to mW. The STEP probe is calibrated against our unique, Optical TRAP Detector and is accurate to +/- 2.0%. It can also be calibrated with a 1000°K Black Body source for broadband applications. It is an ideal Calibration Standard for your Radiometric or Spectra-radiometric measurements: 0.25 to 15 µm.
The STEP probe is available with a 5 mm or 9 mm diameter detector element, that includes our OB black absorbing coating. Each probe is composed of a low noise detector hybrid, thermistor, TE cooler and heat sink. It has an SM1 threaded front bezel, for easy addition of IR filters, light cones, fiber optic connectors and more. Two ¼-20 threaded, in-line post holes ensure stable optical alignment.
The STEP-45 or STEP-49 includes the STEP-Controller module. The controller provides power and temperate control and the analog detector output.
