What
What criteria should we use to look for one? It must meet the points listed here: Excellent pictures, simple to operate, depth of focus, large zoom range, good lighting, efficient measuring software, XY measurement table suitable for the task of measuring, and: Really good value for money!
The three models in the KITOZOOM offer precisely these qualities
To minimize the difficulty of choosing, we first inform you of the technical characteristics and operation of the optical system. The following pages describe the three standard models plus the possible options. The demands on the optical system, lighting, stand and XY measurement table are a result of the inspection- or measuring job. We must take care here to use a magnification which is geared to the required measuring accuracy. If the following information is insufficient for you to choose the system or find the correct components, please call us. We will be glad to help you put the correct model together.
A zoom system consists of the following components: Zoom unit with 6.5x optical magnification, adapter, accessory lens and C-mount adapter. This is in addition to the appropriate USB camera. To be able to work accurately with the Metric measuring software, we need to be in a position to be able to adjust the individual zoom levels in a reproducible way. For this reason the zoom unit has six spherical recesses which a spring-loaded ball can engage when rotated. The levels, marked by numbers, are created as "lenses" in the Metric software and calibrated and saved using a reticle plate with certificate.
ne of the great advantages of the zoom system is that within the zoom range the working distance (end of lens to test subject) does not need to be changed. The distance is adjusted at the highest magnification level and then remains in force for the entire zoom range. The KITOZOOM's scope of delivery includes an 0.5x accessory lens. This way we obtain two zoom ranges, which will be entirely sufficient in 95% of all cases. Four additional accessory lenses (0.25x, 0.75x, 1.5x and 2.0x) are available for larger visual fields or higher magnifications.
The USB 2.0 camera used (two megapixels) with a 1/3" CMOS chip used offers a resolution of 1600 x 1200 pixels. As an option USB cameras can be supplied with a higher resolution and with CCD chips. However we do not often recommend this since hardly anybody uses the corresponding PC hardware to display pictures of 2048 x 1600 pixels or more on the PC monitor. Also the image transfer rate is lower. Below are the visual fields, magnifications and working distances (the magnification relates to a 24" monitor):
With attachment lens 0.25x:
Field of view: 56 mm - 8 mm
Working distance: 310 mm
Magnification: 8x to 54x (on 24" monitor)
With attachment lens 0.5x:
Field of view: 27 mm - 4 mm
Working distance: 170 mm
Magnification: 15x to 105x (on 24" monitor)
With attachment lens 0.75x:
Field of view: 18 mm - 2 mm
Working distance: 116 mm
Magnification: 25x to 160x (on 24" monitor)
Without attachment lens:
Field of view: 13 mm - 2 mm
Working distance: 85 mm
Magnification: 30x to 215x (on 24" monitor)
With attachment lens 1.5x:
Field of view: 9 mm - 1.54 mm
Working distance: 47 mm
Magnification: 50x to 330x (on 24" monitor)
With attachment lens 2.0x:
Field of view: 5 mm - 1 mm
Working distance: 27 mm
Magnification: 80x to 450x (on 24" monitor)
The KITO 10 model consists of the KITOZOOM zoom unit with USB camera, an LED ring light with dimmer, height adjustment using a rack and pinion system which offers quick- and fine adjustment, and the base plate. This 400 x 250 mm large plate is manufactured from 20 mm precision-milled and anodized aluminum. The base plate mounting feet can be individually adjusted in height and fixed. Weight: 10 kg, dimensions: 400 x 250 x 550 – 670 mm.

The KITO 30 model is a configuration with a 50 x 50 mm XY measurement table, with two digital measuring spindles (Mitutoyo Digimatic) and two data cables and an interface (Steinwald) for transmission of X and Y coordinates to the Metric MT measuring software. Why do we need an interface? Imagine you have to measure a test subject with a tolerance of ± 5 µm, but the diameter of the test subject is 30 mm. If we now use a low magnification in order to completely reproduce the part to be measured, we get however a pixel resolution at 30 mm of approximately 17 µm. In so doing the specified measuring accuracy can no longer be adhered to. Therefore we use a suitably high magnification with a low pixel resolution and using the XY measurement table process can transmit the coordinates to the measuring software and there measure with appropriate accuracy.
Of course we can supply the system without interface and data cable if these are not needed. Delivery with the Metric PE is also possible. The cross table can also be supplied for 12 mm diameter instead of 18 mm receptacles. Please note that this configuration has a precision of ± 5 µm via the 50 x 50 mm. Alternatively an XY measurement table with SCD system can be used which offers a precision of ± 2 µm.
Weight: 12 kg, dimensions: 580 x 400 x 550 – 670 mm.

The KITO 40 model is a complete configuration with a separate height-adjustable positioning table. The adjustment range is 80 x 60 mm. The fine adjustment for height is made via the cross table unit. The KITO 40 is the ideal solution for the quick and easy positioning of small parts. As an option we offer a rotation table for the KITO 40 which can simply be placed into the cross table opening. The glass insert plate of the cross table is then used for the rotation table. We would however like to point out that for very fine positioning jobs in the 0.01 mm range it makes more sense to use a KITO 10 model with an appropriate precision cross slide table. (see: EK-100 and EK-150 models). Weight: 13 kg, dimensions: 400 x 250 x 550 – 670 mm.
