Need specific IR thermometer model for experimental physics lab

AI Thread Summary
A user in a nano-optics group is seeking an IR thermometer for a physics lab setup, emphasizing the need for high accuracy and compact size, with a close-range measurement capability of 15-30 cm. The device must feature a USB interface for real-time data collection and compatibility with LabView, with a budget of up to $10,000. The thermometer will be used to measure the surface temperature of a 1x1 cm^2 sample during imaging with an Apertureless Near-field Scanning Optical Microscope. The discussion raises questions about the temperature range, material emissivity, the necessity of non-contact measurement, desired accuracy, and calibration methods for the IR thermometer. The user is also experiencing challenges with the heating and imaging process of the sample.

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?
 
I need to calculate the amount of water condensed from a DX cooling coil per hour given the size of the expansion coil (the total condensing surface area), the incoming air temperature, the amount of air flow from the fan, the BTU capacity of the compressor and the incoming air humidity. There are lots of condenser calculators around but they all need the air flow and incoming and outgoing humidity and then give a total volume of condensed water but I need more than that. The size of the...
Thread 'Why work is PdV and not (P+dP)dV in an isothermal process?'
Let's say we have a cylinder of volume V1 with a frictionless movable piston and some gas trapped inside with pressure P1 and temperature T1. On top of the piston lay some small pebbles that add weight and essentially create the pressure P1. Also the system is inside a reservoir of water that keeps its temperature constant at T1. The system is in equilibrium at V1, P1, T1. Now let's say i put another very small pebble on top of the piston (0,00001kg) and after some seconds the system...
