Ti200, Ti300, Ti400,Ti450 Users Manual Focus The Imager uses the LaserSharp Auto Focus System and an advanced manual focus system. The Ti450 also uses MultiSharp Focus. See MultiSharp Focus for details. Correct focus is important in all imaging applications. Correct focus makes sure that the infrared energy is correctly directed onto the pixels of the detector. Without correct focus, the thermal image can be blurry and the radiometric data may be inaccurate. Out-of-focus infrared images are frequently unusable or of little value. The LaserSharp Auto Focus System, only from Fluke, uses a precisionadjusted and aligned laser pointer to indicate the area of focus. To focus with the LaserSharp Auto Focus System, depress the secondary (black) trigger on the Imager handle. Aim the laser pointer at the target. When satisfied with the location of the laser pointer, release the trigger. The system automatically, rapidly, and reliably focuses on the precise point where the laser was aimed. Note • The user can enable and disable the LaserSharp Auto Focus System. • The laser pointer is aligned parallel to the infrared lens. If using AutoBlend Mode, the laser pointer dot will always be positioned just above the center point marker on the LCD display. However, it is easier to use your eyes to locate the visible laser pointer on the object under inspection. To focus with the advanced manual focus system, place finger on the electronically-driven focus wheel control and rotate the control until the inspection object is in proper focus. Note The user is able to use the advanced manual focus as a manual override of the LaserSharp Auto Focus System. 18

Focus
The Imager uses the LaserSharp Auto Focus System and an advanced manual
focus system. The Ti450 also uses MultiSharp Focus. See
MultiSharp
Focus
for details. Correct focus is important in all imaging applications. Correct focus
makes sure that the infrared energy is correctly directed onto the pixels of the
detector. Without correct focus, the thermal image can be blurry and the
radiometric data may be inaccurate. Out-of-focus infrared images are frequently
unusable or of little value.
The LaserSharp Auto Focus System, only from Fluke, uses a precision-
adjusted and aligned laser pointer to indicate the area of focus. To focus with
the LaserSharp Auto Focus System, depress the secondary (black) trigger on
the Imager handle. Aim the laser pointer at the target. When satisfied with the
location of the laser pointer, release the trigger. The system automatically,
rapidly, and reliably focuses on the precise point where the laser was aimed.
Note
•
The user can enable and disable the LaserSharp Auto Focus
System.
•
The laser pointer is aligned parallel to the infrared lens. If using
AutoBlend Mode, the laser pointer dot will always be positioned
just above the center point marker on the LCD display. However,
it is easier to use your eyes to locate the visible laser pointer on
the object under inspection.
To focus with the advanced manual focus system, place finger on the
electronically-driven focus wheel control and rotate the control until the
inspection object is in proper focus.
Note
The user is able to use the advanced manual focus as a manual
override of the LaserSharp
Auto Focus System.
