Crack Magnifiers  Manufacturers, Traders, Suppliers

The practical, well thought-out design of our high quality scale magnifier F+C provides you with a multitude of applications for the precise measuring of:

• scripts, line thicknesses, distances on plans and drawings, etc.
• drillings, hole spacing, profile gauges, facets, angles, etc.

The consistently further developed, tried and tested scale magnifier is placed directly onto the object to be measured, the length can then easily be read off the precision scale built in on the bottom. Focusing makes it possible to adapt to the user's individual vision.
The inclined position of the scale magnifier gives the visual field additional light providing you with an excellent view. Light falls through a special transparent glass, which at the same time protects the measuring scale. The excellent sharpness in the reading field is achieved with the triple-lens. The scale magnifier comes in a break-proof case.

The most important feature of the crack magnifier is the sloping stainless-steel plate in the base. A scale with increments in tenths of a millimetre is etched into this plate. This measuring instrument is focussed by means of its height adjustable lens system. The crack magnifier is particularly suitable for checking and inspecting cutting edges on drill bits and milling tools in the metal processing industry. Especially for applications in this field, the durable stainless-steel scale is far superior to a glass scale. The crack magnifier is available in 8x and 10x magnification

Sturdy and accurate: The crack magnifier with durable stainless steel scale.

A classic is the crack magnifier: a robust all-metal design with distortion-free (aplanatic) optics. The most important component of the crack magnifier is the 45° inclined stainless steel reticle in the base. It has an etched 0.1 mm pitch. This measuring instrument can be focused by its height-adjustable lens system (sliding focus). The crack magnifier is particularly suitable for checking cutting edges on drills and milling cutters in metalworking. Especially in this field of application the stainless steel graduation is superior to a glass scale, as the latter can scratch very quickly. Reading the scale is very easy, because the sloping structure allows light to enter the scale well, but does not reflect it when the light is very strong. The crack magnifier is shown in 6-fold, 8x and 10x magnification supplied. The crack magnifier is also often used by technicians in the construction industry to measure crack widths in concrete. The eyepiece can be removed from the holder for non-contact inspection. The scales are of course available individually as spare parts.
The optics of the 6x and 8x crack magnifiers RL-B consist of two aplanatically arranged plano-convex lenses made of optical glass. However, the RL-B-10 has shown an increase: It is made of an achromatic lens (two cemented lenses) and two single lenses. Therefore the 10x crack magnifier is an apochromatic lens. An apochromatic lens system combines the sharp-edged imaging of an aplanatic lens with the chromatic aberration correction of an achromatic lens and is therefore particularly suitable if, in addition to the very good and distortion-free imaging of an object, the color of the object is also to be displayed as 'true' as possible. This also results in a longer working distance and considerably improved lighting conditions. This higher quality optics also results in the price jump from the 8x to the 10x version. A special feature of the RL-B-6 and RL-B-8 is that the optics have an 8° oblique view to the pitch. The RL-B-10 on the other hand is provided with a vertical view. The interior of the stand of all three magnifiers is painted matt white to ensure even light distribution. The stable metal construction of the housing guarantees a long service life of the measuring magnifiers.
