Here is how thermal imaging devices work...

A special lens focuses the infrared light emitted by all of the objects in view.

The focused light is scanned by a phased array of infrared-detector elements. The detector elements create a very detailed temperature pattern called a thermogram. It only takes about one-thirtieth of a second for the detector array to obtain the temperature information to make the thermogram. This information is obtained from several thousand points in the field of view of the detector array.

The thermogram created by the detector elements is translated into electric impulses.

The impulses are sent to a signal-processing unit, a circuit board with a dedicated chip that translates the information from the elements into data for the display.

The signal-processing unit sends the information to the display, where it appears as various colors depending on the intensity of the infrared emission. The combination of all the impulses from all of the elements creates the image.

There are a few key Manufacturers when it comes to thermal imaging.  

ATN: produce such well knows devies as ThOR-HD thermal scope, BINOX-THD thermal binoculars, and OTS-HD thermal monocular.  

FLIR/Armasight: the largest maker of consumer level thermal products is well knows for their full product line.  Zeus thermal scopes, Q14 and Scout monoculars, Helios and Scout binoculars and many more.

Pulsar: a very popular brand for digital night vision and thermal imaging.  Key products include Pulsar Trail and Apex thermal scopes and Pulsar Helion and Quantum thermal monoculars.

Seek: mobile device mounted thermal cameras are the main products of this brand.

Delivery Time and Manufacturing Process for FLIR Thermosight Pro 4-16x50 60Hz PTS536 Thermal Weapon Sight with Boson 320x256:

Most of our manufacturers do not keep products like FLIR Thermosight Pro 4-16x50 60Hz PTS536 Thermal Weapon Sight with Boson 320x256 assembled on the shelf. Night Vision tubes are kept separate from the body of the unit. When the order is placed, the manufacturer starts the order processing and assembly process which includes the following:

  • Order processing - we collect all the necessary information including address and phone numbers. We also make sure that our customer ordered the correct product for their needs and that the product can be exported by US law to the country of destination. In some cases a signed export compliance form is required.
  • QC - in this step the manufacturer will inspect all individual parts which will be used to assemble the night vision device for any defects.
  • Production & Assembly - during production, all the parts are put together. Night Vision tubes in inserted into the body of the unit and all the complex electronics for the device are connected. This process takes place in a special lab called the "clean room" as even a small speckle of dust can cause undesired optical effect.
  • QA - one the night vision device is assembled, it goes through a rigorous testing process to make sure it meets all the expected specifications and all parts function as expected. For this most manufacturers have a special "dark room" designed to allow testing of the units without causing incidental damage to the night vision tube by exposure to bright light.
  • Packaging - this is a key process as well. In most case your night vision device will be shipped to you directly from the manufacturer but sometimes needs to be sent to us first. In either case items need to be packaged securely to avoid any kind of damage during transportation.
  • Shipping - as described above items will most of the time ship from the manufacturer. For most domestic orders (unless shipping to POB or AFB) a premium shipper like FedEx or UPS will be used.

Only by following the above steps can we along with our manufacturers bring you - our customer - night vision products of highest quality, However as you can understand the above process can take several days to complete. For example if your device fails QA, the entire process restarts. Also at QC stage a manufacturer may realize that the tube they have in stock has a defect and a replacement tube needs to be ordered. Due to the complexity of this process, it is prudent to expect 3-4 business days for production and handling of the purchased device. Keep in mind that this process is designed to guarantee your satisfaction with the night vision device of your choice.  It occasionally possible to expedite the process for urgent orders but addional fees or other restrictions may apply.

Questions on FLIR Thermosight Pro 4-16x50 60Hz PTS536 Thermal Weapon Sight with Boson 320x256

From on

Q: Will the new thermosight scope. 4-16x50 with boson. 320x256 be comparable to the armasight. 640x520 17 micron scopes with the same. 50 mm. Lense..just wondering about the performance or should I wait for the 640 units to come out...

A: Hi Dee. I cannot tell you that a new core is going to make a 320 thermal scope perform the same as a 640 scope. You simply do not have as many pixels in that image. The real question is if you need the 640 resolution for what you will be trying to achieve with this unit. If you describe your hunting habits, we can tell you what parameters will be important.

From on

Q: With the above question in mind, would you expect better performance with the 12 micron core as compared to the current 336 in 17 micron or be about the same?

A: Hi Wayne. Smaller pixel size allows for a sharper image and clearer image.

From on

Q: I have been waiting on the Flir boson core 12m since June (the 50mm). When will it be available? In April Flir started saying June, here it is August. I would like to know when because if it is going to be much longer I will go with another scope. Thank you and am looking forward to your answer.

A: Hi Mike. I understand your frustration. Unfortunately this is typical of night vision manufacturers. Often products are marketed ahead of time and then production process takes longer than anticipated. At this point we are expecting another 3 - 6 months before this scopes is on the market. If you are looking for a scope for this hunting season, you will probably need to get a different unit. Please let us know if we can suggest something and potentially offer a special discount.

From on

Q: any idea of how much these are gonna cost?

A: Hi Weston. It is hard to be sure until the manufacturer releases them. It all depends on prices of other thermal scopes on the market at the time.

From on

Q: Is the front lens adjustable on the 533?

A: Hi Pookie. by adjustable, do you mean ability to zoom thermosight scope using the front lens?

From on

Q: Is the FLIR 30Hz or 60Hz?

A: hi Winston. All models of FLIR Thermosight Pro thermal scopes with Boson are 60hz. We had old data on the page and have corrected it now. Thank you for pointing this out.

From on

Q: Can you recommend a scope you have for sale now that’s comparable to the one in this thread? Thanks!

A: hi Steve. In terms of capabilities, this one is probably the closest:

From on

Q: Does this PTS536 record audio

A: Hi Kenneth. Thermosight Pro thermal scopes do not record audio. If this was important to you you would need to record audio on a standalone device and then match the streams in some video editor.

From on

Q: Does this scope have a built in range finder?

A: Hi Joe. FLIR Thermosight Pro thermal scopes do not have a built in rangefinder but do have a connector port for external optional Laser Range Finder Connections.

From on

Q: Is this thermal waterproof or is it just water resistant?

A: Hi Michael. Officially FLIR Thermosight Pro thermal scopes are rated as waterproof. Naturally this does not mean that you should soak it in water. However, it will be fine if exposed to heavy rain dropped into a puddle.

From on

Q: when is flir going to release the PTS536

A: Hi Kevin. We are expecting a shipment from FLIR of Thermosight PTS536 to be sent on Friday which means we will be able to ship towards the end of next week. That's based on what FLIR is telling us currently. With that shipment we will have enough to cover a couple of new orders if they are placed soon. So if you are in the market for this scope, I suggest to not delay.

From on

Q: Hello - I see it says there are "laser range finder connections". Can you explain more about that? What brand is compatible? Does Flir have a specific range finder in mind? Will my Sig Kilo1400 work with it? I'm strongly interested in this scope but integration with a range finder (or not) is a dealbreaker for me and if it's not easy to set up and clean to work with I'll go to a different product. Thanks!

A: Hi Brett. The laser rangefinder connections are for a FLIR unit which has not been released yet. If you need one, I would suggest a Zeus Pro unit which you can get the external rangefinder for. It is trivial to integrate them.
