What is µRuler?
µRuler is a micro-ruler to measure micro-objects, especially working with a magnifier or microscope.
For the ruler in daily life, usually the minimum scale is 1mm, in µRuler, 1mm will be divided into many small scales.
Two different µRulers were designed for dedicated purpose to meet multiple application: µRuler M and µRuler Q.
Why you need µRuler?
When we measure everyday items most of us will grab a ruler in order to make a measurement. When we observe the micro-objects using a loupe or microscope, it is extremely important to know their size because we lacks the sense of size in micro-world.
Therefore, like for the everyday items, we need a micro-ruler to measure the size in micro-world.
How to use µRuler?
- Direct measure
µRuler can be used directly under a microscope or loupe for speedy measuring of small parts, grooves, slots, line widths, holes, and chamfers.
- To calibrate the reticle
With the eyepiece reticle installed on microscope, put µRuler under the microscope, focus so that both scales are clear in focus and lined up at the "0" point to make calibration of the reticle.
- To calibrate the software scale bar
Dedicated software for microscope usually enable the embedding of a soft-scale bar on the micrograph, it need to be calibrated to ensure accuracy.
Why µRuler is such a low cost yet high quality?
Pilot test and quality validation
A small amount µRuler M was already made, the quality and accuracy were validated.
Calibration certificate
In addition to the internal quality verification by microscope, one μRuler was submitted to third party authority, National Center of Measurement and Test for East China to test the accuracy. Calibration certificate reported U=1.5μm, k=2. That means when coverage factor K=2, the expanded uncertainty U=1.5μm. In other words, with a probability of 95%, the value of the measurment is within the range of ±1.5μm. It is a very good accuracy for μRuler.

Why your support is so important?
We plan to start this project to build this small and low cost ruler to help more and more people in microscope community. Your support is highly appreciated and very important for the success of this project, as a minimum volume need to be reached for µRuler production in large scale with a low cost.
About us
We (Shanghai Qingying E&T LLC, www.mobile-scope.com) focus on the development and manufacture of micro-photography product. We started quite a few years ago and get several patents authorized on this field since April of 2012.
We built several products line to help our customer with the best smartphone based tools and instruments in different application:
- Industry– PCB, printing, fabrics, fine mechanics , abrasives
- Medical– in hospital dermography, parasite
- Garden– plants, insects
- R&D– failure analysis, material observation, defects observation
- Hobby– banknote, postage, vintage
- Daily life– education, office application
- Forensic – observation and records
Risks and challenges
Development of this product has gone through prototyping, evaluation and improve the concept cycle many times. a low volume has already been made and validated.
If the project is not successfully funded, though the products could be made by low volume, the cost will be relative high. So, your support is very important to make this product to be available to microscope community at affordable price.
