The freely adjustable polarizer helps to reveal more detail or to enhance the contrast on the surface by reducing or eliminating the reflections. This model also includes the adaptable cap design, which is a detachable and interchangeable front cap design used in the Dino-Lite Edge series aimed at satisfying various applications. Different caps have been developed for better adaptability for more applications. Simply removing the cap would yield more working distance which brings added convenience in the higher magnification range, or have better accessibility to the full range of magnification. Measurement (MS) - Use simple tools to draw lines, shapes, and text annotations on the image. Calibrate and measure dimensions including lines, circles, and angles. Polarization (PZ) - Built-in adjustable polarizer greatly reduces glare on reflective surfaces. Interchangeable Cap (IC) - A selection of swappable end caps for different applications.
