Need specific IR thermometer model for experimental physics lab

jpestana

I work in a nano-optics group, and need an IR thermometer with certain specifications. Online I have only come across cooking thermometers and industrial thermometers, so I need help finding one for a physics experimental lab setup.

Specifications:
- high accuracy, and pin-point surface temperature reading
- close-range (must be set-up close to sample, 15-30 cm (6-12 inches))
- compact (not too bulky)
- USB interface to computer for real-time data gathering
- compatible with LabView (as a VI, Virtual Instrument)
- price range: max of $10,000.00 USD

This IR thermometer will be used to measure the temperature of a sample about 1x1 cm^2, which will be imaged by an Apertureless Near-field Scanning Optical Microscope (ANSOM), which uses a tip like an AFM (atomic force microscope). We are using a heater to heat the sample, taking resistance measurements, and then will use the IR thermometer to take the surface temperature of the material (since there is a temperature gradient between the heater surface and the top surface of the material being imaged.

If you have done anything like this before (heating and imaging a sample), please let me know. We are having difficulties with the imaging/heating as well.

Thanks!

What is the temperature range?
What is the material (what is the emissivity in the IR)?
Why does it have to be non-contact (there are thermocouples that are quite small)?
What is your desired accuracy, and how do you plan to calibrate the IR thermometer?
