Graticules Ltd. Inspection (Portable) Microscopes

Use for quality control and other inspection requirements

Portable microscopes
This type of inspection microscope goes by different names in different parts of the world. In the far east, such instruments are called "stand" microscopes because they can independently "stand up". And those with a wider field of view are called "wide stand" microscopes.

In Europe, the tendency has been to call them "portable" microscopes. And in the USA the tendency has been to call them "inspection" microscopes. But no matter where you are and what you want to call it, these high precision made instruments with outstanding lens systems are made to do the very best up-close inspection of a wide range of different materials under different circumstances.

The manufacturer, Graticules Ltd., which is a part of Pyser-SGI in the UK, has a more than 75 year history for making the finest inspection microscopes in the world. They are bit more expensive than other inspection microscopes, but for those requiring the very finest in performance, then this is the microscope for you.

The Inspecta™ line of inspection microscope by Graticules is based on essentially the same body which then can be purchased either with or without illumination, with our without a superbly crafted wooden carrying case, and of course, with different magnifications. One even has the option of purchasing with an "erecting" prism, a feature not generally found on this type of inspection microscopes.

Specifics about the microscope line:

These highly robust instruments are designed for use both in the field and in the laboratory, to yield results as close as possible to those achieved by full size (and infinitely more expensive) light microscopes. They are particularly useful for analysis where standard microscopes can not be used. The results obtainable can relieve the pressure on the standard microscopes in a busy laboratory. In the field, the high portability of the microscope provides a vital tool to the field people, and engineers who have to make snap decisions while still on site.

The highest quality optical elements are fitted into the metal body. A rotary knurled sleeve focuses on the specimen, with 20mm adjustment possible. The whole instrument base allows adequate daylight to fall on the specimen for most viewing purposes. For working under more difficult lighting conditions, an adjustable clip-on light source can be selected.

Measurements are made using a reticle (sometimes called a graticule and sometimes also spelled reticule) scale incorporated into the focussing eyepiece. Reticles are calibrated either in metric or inch units and their readings refer directly to the specimen irrespective of size or position.

Typical applications:

Electron and light micrographs
Artworks
Negatives and transparencies
PCB tracks and holes
Material imperfections
Metal finish
Slits and apertures
Printing and packaging
Particles and droplets

Microscopes with "erecting prism":
The following three models have been built with an erecting prism so that an inverted image can be viewed "right side up". The prism rotates the image 180° which often times helps reduce confusion when viewing an image.

Magnification	Useful field of view	Calibration	SPI #	Each	In Stock
20x	6 mm	4 mm in 0.02 mm	09775-AB	$ 1004.73	No

Selection of the clip-on illuminator:
Not everyone needs an illuminator but for many it is indispensable when lighting conditions are not good and a good light box is not available.
