2.0MP 50X to 600X zoom 8 ring LED patent design handheld USB digital measurement microscope

1. Zoom function: low magnification for wider field searching and high magnification for detailed message checking.
2. Capability of capturing image in high resolution:
Display resolution: 1600*1200
Picture resolution: 1600*1200
Video recording resolution: 1600*1200
3. Capture settings: Software allows you to adjust the gain, resolution, WB, contras, exposure time, and converting image direction.
4. Image amendment: RGB color and gray scale.
5. Make measurement and compare with the movable software reticle calibrated.

One set of conjugate lenses offers two different magnifications, which the low magnification is for wide field view and the high magnification is for detailed inspection; long working distance is suitable for assembly of fine equipment.

The combination of low optical magnification and high digital magnification has it be possible to run out of room without a stable platform; Big focus wheel is good for zooming and focusing easy and smoothly.

UVC design in use of Window XP, Vista and Windows 7; Power supply of LED coming from USB port; Wide dynamic range offers high quality images

To support operation model of capture and show images in top resolution of sensor; movable reticle is usefully for measurement and indication of target; 7 languages of software for selection.

With a 10mm/ 0.1mm glass micro ruler (Figure 1). to calibrate the movable reticle of the software (Figure 2).

At 40X, the 1mm length of ruler is covered by 13.75 units of reticle, so the division value of reticle is: 1 / 13.75 =0.072mm (Figure 3).
At 240X, the 1mm length of ruler is covered by 52.0 units of reticle, so the division value of reticle is: 1 / 52.0 =0.019mm (Figure 4).

To measure the narrow gap size with the reticle calibrated at the same setting of magnification 40X (The settings of image resolution and screen display resolution keep unchanged). By moving the microscope with your hand and to draw the position of reticle with your PC mouse you can have the vertical line of reticle cover the tiny gap, and read out the divisions, the width of gap = 4.0 *0.072=0.288mm (See E-area of Figure 5).

Figure 6: Close view of waviness of the metal part at 240X

Inspection in low power and high power: You can find the defect area in 3D viewing at 40X, (See A-area of Figure 5). By turning the focusing wheel to let the lens move down to the metal part, you can get a high magnification (240X) position to view the detail of surface roughness (See Figure 6：F-area of Figure 5 amplified). Of course, you can measure the interval of two adjacent waviness lines: the width of waviness =3.0 *0.019 =0.057mm,
