PEAK-Optics Telecentric Loupe 1999, 7x
PEAK 1999, telecentric loupe 7x
scale loupe with glas scale, aplanat, achromat, focussable
The PEAK measuring magnifier 1999, 7x is a "telecentric" system, meaning that a small opening is present at the focal point of the lens system, allowing in addition to measurement of the length and width of flat objects, measurement of three-dimensional objects such as spheres, cylinders, etc. without parallax errors. The telecentric PEAK measuring magnifier 1999 corresponds in principle to an expensive profile projector.
The system of lenses consisting of three elements in two groups, was designed specifically for this purpose.
To use this magnifier first set the distance between the scale and lens systems by turning a knurled outer tube until the scale is visible sharply through the opening with the largest diameter (3 mm), which can be adjusted with the rotating ring on the tip of the magnifier. Then position the magnifier on the object to be measured so that the measuring scale is in contact with it and read the length off on the scale.
The scale is subdivided into increments of 0.1 mm over a length of 20 mm, so that the length of objects can be read off with an error quota of less than 0.03 mm.
When measuring three-dimensional objects, the opening should be set to the smallest diameter (1 mm) or, even better, use the one with a 0.5 mm wide slot.
The slot should be perpendicular to the line, whose length is to be measured. Even in this case, parts of the object not in contact with the scale may not be sharp, because they are not properly focused. Errors cannot be made when measuring the length as long as the centre distance between the unfocus images is measured, because the minimum brightness of timages resulting from the small opening is compensated by higher illumination of the object resulting from the characteristics of the telecentric system.
We supply this scale loupe in standard with a metric scale, length 20 mm with 0.1 mm division in a synthetic leather bag
Optionally all other scales for the Loupe 1975 can be used for this telecentric loupe.
Replacement scales and accessories can be found here:
Of course we offer at extra cost a calibration certificate according to VDI / VDE / DGQ 2618 page 27 Ü.
