Chapter 1: Introduction
Description:
The T-7 Thermal Goggle/Binocular is a rugged, lightweight and powerful Infrared optic that can be hand-held, helmet mounted, or mounted on a head harness. By using the 2X internal digital zoom and adding an optional afocal germanium optical lens, the T-7 pro­vides potent 6X long range thermal surveillance and acquisition.
The sensitive uncooled thermal detector and high resolution display provides crisp “white hot” or “black hot” images regard­less of ambient conditions. A colorized capability is available at user request. While night vision technology relies on amplica­tion of ambient light or assisting illumination, thermal devices are completely passive, sensing extremely minute temperature dif­ferentials. The T-7 Thermal Goggles therefore acquire targets in daylight and complete darkness while “seeing through” obscurants
such as smoke and haze which often hinder image intensication
devices.
Designed for law enforcement, military and commercial use, the T-7 is idea for reconnaissance and surveillance, perimeter secu­rity, wildlife observation and control, locating oil spills, and geo­thermal event monitoring in addition to a wide variety of other applications.
The T-7 combines a highly sensitive, unclooled, thermal detector with the new 640 X 480 LED display integrated into the familiar AN/PVS-7D housing, ensuring accurate images and compatibility with accessories such as the Mil Spec Head Harness and Helmet Mounts. The comfortable, light weight T-7 provides a powerful advantage during both day and night operations.
What is Infrared?
Infrared energy, often referred to as “infrared” or “IR”, is electro-
magnetic radiation that travels in a straight line through space, the same as visible light. Although infrared shares some of the prop­erties of visible light, its different wavelength has several unique characteristics. For instance, materials that are opaque to visible light may be transparent to infrared, and vice versa. An example
of this difference is the ability of light intensication devices to see
through glass and plastic while thermal detection devices can­not. Unlike visible light, given off by ordinary objects only at very high temperatures (e.g. light bulbs), long wavelength infrared (7-14 mm) is emitted by all objects at ordinary temperatures. This means infrared is all around us all the time, even in the dark. Dif­ferent objects give off varying amounts of infrared, depending on the temperature of the object. The T-7 is designed to sense differ­ing amounts of long-wavelength infrared and display the scene in real time for the user.
WARNING!
DO NOT POINT THE T7 THERMAL DEVICE AT EX-
TREMELY HOT OBJECTS OR THE SUN TO AVOID
DAMAGING THE UNIT!

Chapter 3: Operating Instructions
The T-7 is easy to operate. See below instructions for opera­tion. Contact SPI Corp. for additional information or assistance at (702)369-3966 or email sales@x20.org .
Power source:
The electronic circuit is powered by three (3) replaceable CR123 batteries. For installation in darkness, be aware that the positive
(+) end (nipple end) of each battery must be inserted rst into the
battery compartment.
Activation (IR/pull position):
To turn the unit on, pull the switch out (switch is partially spring­loaded) and rotate two clicks clockwise (CW) to the IR position. The circuit will energize, wait a few seconds, the thermal image will then be displayed. This time delay is used to cycle-start the sensor circuits.
Reset/Off-ON-IR/pull Power Switch:
When the switch is in the OFF position, the T-7 is not energized.
Focus adjustment:
First, carefully rotate objective lens clockwise or counterclockwise to sharpen focus. The user should be able to focus at a minimum
three feet (3 ft) to a maximum of innity. Typically, the innity

WARNING!
Ensure that the switch is in the OFF position before
installing or removing batteries!

setting covers all focus from 15 feet to innity. Next, focus each eyepiece, in accordance with your specic optical correction, from
-6 to +2 diopter. Look for the sharpest image you can achieve of the scene you can see on the screen. Rotate the eyepiece as necessary for sharpest image. Finally, slide either or both of the eyepieces towards or away from your nose so that one distinct im­age is viewed.
White-Hot/Black-Hot button switch:
The T-7 always starts in the white-hot mode. The T-7’s white hot/ black hot polarity is selected by using the bottom spring-loaded
momentary button on the front-right side of the unit. Briey press
the bottom button to switch between WHITE-HOT and BLACK­HOT polarities.
2X Digital Zoom:
The 2X switch is a digital zoom that switches the unit from 1X to 2X to 3X when the top button is depressed. When going from 1X to 2X to 3X the objective focus will need to be adjusted slightly for optimal performance. The unit starts in the 1X mode.
Head Mount Assembly with Brow Pads:
Adjustable head assembly that secures the T-7 to the operator’s head providing hands free operation.
CAUTION!
Do not touch the lens face
Chapter 4: Deactivating, cleaning and storing the system
Deactivation:
Turn off the system by rotating the switch two clicks counterclock­wise (CCW) to the OFF position. View through the eyepiece to
conrm the system is indeed off.
Battery removal:
Unscrew the battery compartment hatch, remove all three CR123 batteries, and store these in the carrying case or bag. Close the battery compartment. If disposal of the batteries is required, please follow your organization’s hazardous materiel disposal procedures.
Clean outer unit:
Use a moistened clean cloth to wipe the outside of the T-7, EX­CEPT FOR THE OPTICAL SURFACES. A very dilute detergent solution is permissible. Dry with a soft clean cloth, or allow unit to air-dry before storing it.
Clean optics:
Use a moistened lens tissue, if necessary, to wipe the optical sur­faces, using a light, circular motion. Discard each lens tissue after one use, to avoid transferring grit or foreign matter onto the lens surfaces. Dry with a clean, unused tissue.
CAUTION!
Ensure that you turn the knob two clicks, otherwise
the screen will be off but the T7 will still
be energized.
