Stage Micrometers for Transmitted Light:

Crossed scales of 100 separate and distinct divisions (Style PS16)

Total length of micrometer scale: 1 mm

0.01 mm (10 µm) per division

The difference is the traceability: 

  1. No letter or T: Traceable (no certificate)
  2. G: Graticules Ltd. Certificate
  3. C: Certified UKAS
  4. N: Certified NPL

  
These high quality stage micrometers are used for routine calibration of a variety of optical measuring instruments, from light microscopes and eye pieces to x-y stages and optical benches. The stage micrometer is actually used as a "specimen" in order to calibrate for example, an eye piece reticle. For the professional light microscope user or researcher, these are the ultimate calibration standards for their light microscopes. This means that the stage micrometers are available "traceable" either with or without a Graticules (e.g. Pyser-SGI) certification, or with a certification through National Physical Laboratory (NPL) or UKAS (United Kingdom Accreditation Service).

Are all stage micrometers created equal?
Absolutely not! At the risk of sounding like we are making mountains out of mole hills, we want to make the following "sales pitch" as to why one should consider spending a bit more for their stage micrometer but at the same time, getting a far higher quality product and package:
All SPI Supplies stage micrometers come with an engraved serial number in the slide mount. If we did not incur the cost of this special unique engraving, we could sell the stage micrometer for a good 20-25% less. But we decided to not offer such an unmarked product because all calibration programs, including those based on ISO standards, require the use of uniquely marked standards. So if you think you are seeing a "better deal", ask if the slide mount is permanently engraved with a unique serial number. 


All SPI Supplies stage micrometers come in a stainless steel mount instead of a much more inherently less expensive aluminum mount. If you are comparing prices, make sure you are comparing apples to apples and that you are comparing another stainless steel mount and not aluminum. Most experienced users of stage micrometers prefer stainless steel for a variety of reasons, one being the heavier "feel" which makes them easier to handle. But those who are more economy minded, we can offer a line of lower cost stage micrometers in aluminum frames.


All SPI Supplies stage micrometers come in a polished wooden box with full cushioning in order to provide the highest level protection. Almost all stage micrometers featuring a lower price come either in a flimsy (in comparison) plastic box if indeed a box is furnished at all. 
The lines on the SPI stage micrometers have absolutely the smallest standard deviation in center-of-the-line positioning as well as the smallest standard deviation of the line width. With some of the lower priced stage micrometers, it is like comparing night to day, the differences are so obvious. Unfortunately, it is not all that easy, on a website to communicate such differences.


Beware of "all glass" stage micrometers. Why? Well, drop it once and your expensive stage micrometer is no more. You will instantly understand why SPI has a philosophy of "no all-glass". Now we are not going to guarantee that you cannot break one of the SPI stage micrometers in a stainless steel mount, but the SPI micrometers are infinitely more robust than the all-glass ones and will over time have a much longer useful life time.
