Thermal Imaging

Please note that most thermal devices are built per order.  It may take 3-5 days or more for your order to ship.  If timely shipping is important to you, please, contact us to verify availability prior to ordering. 

Thermal devices can produce various types of images.  Some are color others are monochrome.  In either case change in shade or color indicates temperature differences.

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 Opgal Therm-App HZ 25hz Thermal Camera for Android Devices:

Most of our manufacturers do not keep products like Opgal Therm-App HZ 25hz Thermal Camera for Android Devices 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 Opgal Therm-App HZ 25hz Thermal Camera for Android Devices

From on

Q: What is the warranty provisions for this camera and how is it handled since this is an out of country product ?

A: Hi Kevin. ThermApp is covered by a standard 1 year warranty. Opgal has the policy described here: http://therm-app.com/end-user-license-agreement/ . If there is an issue with the unit you would need to obtain RMA and send it back to them for service. We also sell an extended 3 year warranty which covers you for 3 years and kicks in after the manufacturer warranty runs out. They will either pay for repair or replace the unit.

From on

Q: Question #1 Can you see a mouse/chipmunk/squirrel behind the walls or in the attic while looking from inside the room? Question #2 I am looking for a thermal scope that will see the rabbit's heat signature in the thicket or a squirrel's heat signature while they are running through the trees when the leaves are out. I'm not looking for some unidentifiable blob on the scope but something kinda clear from 10 to 75 yards so that I KNOW what I am looking at. I also have to after rats, raccoons and opossum at night. Dennis Varmint Eradicators http://www.varmint-eradicators.com/

A: Hi Dennis. Opgal thermal will not see through the walls and neither will any other device we sell unless the wall itself is heated up by the object behind it. For the scope question, can you clarify if you are looking for a weapon mountable device or a handheld monocular?

From on

Q: Do you have picatinny rifle mount accessory and does it keep the camera from rotatingon the tripod attachment screw? In other words, will the rifle adapter zero when detached and re-attached? Thank you

A: Hi David. We do not have any mounts which allow Therm-App to be mounted on a weapon. I don't think it is rated for recoil. Have you seen such a setup?
