Simple, Fast, Convenient
Fast and efficient refracting is a simple push-of-a-button with the AP250. Randomly select any of the 33 test charts or use the program feature to create two user-defined chart sequences. The masking controls allow you to isolate horizontal and vertical lines or individual characters. Additionally, you can apply the red/green filter or polarization filter to any chart.
The AP250's focusing controls are adjusted quickly and easily enabling you to sharply focus slides for projection distances of 10 to 26.5 feet.
Bright, high-contrast slide images are provided by the unit's 2000 hour long-life halogen bulb.
All Fields are required unless noted otherwise.
