Our Raytek®
inventory is gone - that's it - we have sold every Raytek Noncontact Thermometer
we had in stock! Although we no longer stock Raytek®
we still recommend Raytek® Temperature Guns!

Raytek®
Non Contact Thermometer Laser Sighting Guide
Understanding
the Laser Sighting System on your Raytek® Thermometer is very important!
The laser sighting capability is very different on the different models of
Raytek® IR thermometers! The higher the price the better laser sighting
distance and pattern – or in other words – you get what you pay
for! Please call us at 704-233-9222 or send
us an email if you have questions - thanks!

Sighting Type: Laser Point
Single point laser,
coaxial or offset
D:S = 6:1 on MT4
|
 |
| MT, KX, ST20 |
|
| Advantages: Easy to see. Aims the unit at the center of the target’s IR energy spot.
Limitations: No indication of target size or measured area. User must calculate or look up the target size.
MT 4 D:S = 6:1 For example: at a 36" Distance you are actually measuring a 6" spot not the center of the laser dot!
|
Sighting Type: Laser Guide
Circular laser,
offset, cone beam
D:S = 50:1 on ST80
|
 |
| ST30, ST60, ST80 |
|
| Advantages: Contains a large portion of the target energy within the circle while helping aim the unit using the center dot.
Limitations: Parallax, especially in the near field. Does not track the IR beam profile--apart from the focal point, the relationship of the IR circle to sighting is not constant.
ST80 D:S = 50:1 For example: at a 60" Distance you are actually measuring a 1.7" spot (per Raytek®)!
|
Sighting Type: True Spot
Circular laser,
coaxial, skew beam
D:S = 60:1 on MX
|
 |
| MX |
|
| Advantages: Highlights approximately 90% of measured IR spot at all distances – sighting reflects the actual target size. Especially useful in the near field and for close-focus.
Limitations: Largest investment.
MX D:S = 60:1 For example: at a 32.8 ' Distance you are actually measuring a 11" spot (per Raytek®)!

Use the chart above as a starting point for choosing a type of laser sighting. Other important factors in choosing the type of sighting for your application include: target distance, the thermometer’s optical resolution, target size and cost. A final key element in evaluating sighting systems is the temperature relation of your targets to their background.
