Field portable pocket measuring microscope
* Battery powered illumination, (Qty 2 AA Batteries not included) Magnification 40X.
* Optics has reticle in field of view to use for measuring.
Reticle Divisions for Measuring: 0.05mm (20 divisions per mm).
* Reticle has divisions across X direction for 4mm distance (80 divisions in X) and half of field on Y direction for 2mm (40 divisions in Y, half field).
* Microscope folds shut to close and turn off light. Open to turn on light.
* Has focusing adjustment knob that moves optical lens so object can be focused in the view.
* Tilts when open to allow light to shine at angle for optimal reflected illumination.
* Clear base shroud allows easy viewing of specimen being examined while microscope sits on top.
* Microscope sits on top of specimen during examination.
* Field of View, Diameter: 1/8" or about 4mm.
* Includes black leather storage case.
* Overall Size 1- 3/4" x 5-1/2" x 7/8".
* No need for instructions. Has arrow marked open for insertion/replacement of battery.
* Has one simple knob that is turned to focus.
Light turned on by simply unfolding and opening the microscope.
* Accuracy of Measurements: As any microscope is focused, the width of the field of view in the viewing eyepiece also changes.
* As this width changes, so does the effective magnification.
While a microscope has a nominal magnification, such as 40x, the precise magnification needs to be calculated.
* To obtain precise measurements with any microscope, the eyepiece reticle must be calibrated with a stage micrometer, and a mathematical calculation made to know precisely the distance represented by the graduation marks on the reticle.
* If you need to make precise measurements, you will need the stage micrometer that we can provide as an option.
* High Quality Construction!
* This stage micrometer is listed as a separate item on our other ads.
