The Peak Measuring Magnifier 7x is a handy and accurate optical measuring instrument. It consists of a combination of lens and scale and is very similar to our proven Peak measuring magnifiers with 7x and 10x magnification. Compared to conventional loupes, the Mini Comparater is smaller, easier to transport and cheaper in price. The achromatic doublet has great sharpness and clear resolution. Focusing is convenient via a multi-start screw. The measuring scale has a graduation of 0.1 mm and a measuring length of 20 mm. The contradiction between high resolution and wide field of view has been completely eliminated in this product, providing powerful, precise control. For higher transmission, the lenses are coated with an AR coating (anti-reflective coating). The loupe is supplied with the standard scale.
Field of view: 25 millimetres
Dimensions: 29Øx46 mm
Weight: 28 g
In optics, an achromat is a system of two lenses consisting of glasses with different Abbe numbers (different degrees of dispersion). The system contains a converging lens (usually made of crown glass) and a diverging lens with a smaller Abbe number and thus stronger dispersion than the converging lens (usually made of flint glass). This allows the longitudinal colour error that every simple lens has to be corrected for two wavelengths, i.e. the system has the same cut-off for these two colours.
