QUICK SCOPE QS-L

Height measurement now available from one machine

High-speed image auto focus achieving height measurement now standard equipment. Measurements thus far performed separately using an optical measuring instrument and an indicator are now integrated into one machine.

Reliable small-parts measurement

High-speed 7X optical zoom with an interchangeable objective lens unit provides sharp and bright images. Measures details that cannot even be recognized when using digital zoom.

Highlights hard-to-see edges

High-intensity 4-quadrant LED ring light generates shadows to highlight edges that otherwise would be practically invisible.

Problems with simple dimensional measuring devices

Problems

QS-L solutions

Hard to measure reliably using regular microscope lighting

Some edges cannot be accurately detected and captured when using only the ring light as edge height and shape are so variable.

Indistinct image using ring light

Edge measurement using a combination of co-axial light, ring light and transmitted light

Positive edge detection with co-axial light

Cannot measure micro dimensions due to low magnification

Some micro forms cannot be measured with only a digital zoom.

Measurement of the width of microrecessed-forms cannot be accurately performed due to low magnification

7X optical zoom unit with interchangeable objective lenses enables measuring small parts

Edge capture with the ideal magnification is always available

Measurement of micro radii is easy with the correct magnification

Edge measurement of a stepped feature cannot be performed correctly

Some desired edge contrast cannot be obtained with a simple dimension measuring device that has generally low magnification due to deep focus depth

Edges can easily be captured with the interchangeable objective lens zoom unit

Measurement with optimized optical zoom is available

Height measurement results are not stable

Height measurement with a contact probe

Image auto focus function is equipped as standard

Image auto focus offers sure and highly accurate measurement of target height with the minimum clamping of a workpiece

Unsure about the integrity of measurement results to be submitted to customers

Mitutoyo provides inspection/calibration services using reference instruments that are traceable to the national standard

Generic technology realizes accurate measuremen

7X optical zoom unit with interchangeable objective lenses offers reliable small-parts measurement

Newly designed 7X optical zoom unit with interchangeable objective lenses securely captures measurement targets from wide-field to micro form. In addition, 4X digital zoom is available using software.

High-speed image auto focus enables highly accurate height measurement

Since non-contact measurement requires only the minimum clamping of the workpiece, height measurement can be performed efficiently. Also, in contrast with laser-equipped measuring devices, height measurement is less influenced by the surface roughness of the workpiece.

LED light unit offers a high degree of freedom for reliable edge measurement

The view may vary depending on the type of method used for lighting the workpiece. The QS-L can capture edges accurately by switching between transmitted lighting, co-axial lighting and ring lighting.

Lighting tool (Contrast and brightness)

The lighting tool offers automatic setting of the ideal light intensity so that constant brightness can be maintained. It also eliminates data dispersion caused by lighting conditions.
