What is an autocollimator?

An autocollimator is an optical measuring instrument that can measure angles without contact.

We have a lineup of products that meet various needs, such as those with higher accuracy, those that support higher speed measurement, and smaller ones for integration.

TM-2070

Ultra Compact Tilt Sensor

In order to meet the needs of integration into equipment and handlers devices, it is the world’s smallest model with as much size as possible. (As of October 2020, according to our research)
The image processing unit can measure angles at a processing speed of 60 fps and output data to higher-end equipment.
It is equipped with an APC (Auto Power Control) function, making it easier to use.
It starts up a few seconds after powering up.

Main specifications
Measuring range: φ2.33deg
Measurable distance: 0 to 110 mm φ2.33deg
: 0 to 170mm φ90min
: 0 to 250mm φ60min
Repeatability: 1sec
Number of measurements: 60 times/sec
Dimensions: W38×D42×H18mm

WT-7300 / WT-2600

High-speed, wide-angle models

The measurement range of φ20deg can be measured accurately and at high speed. This is the world’s first automatic collimator system. (As of December 2018, our research)
The measurement data is output in analog (±5V) and supports 10kHz sampling.
It is ideal for measuring and evaluating objects with a wide range of high-speed motion and tilting ranges, such as prism mirror measurement of MEMS mirrors and periscope cameras on smartphones, and tilt OIS actuator measurement of camera modules.

AT – 2060

High-speed tilt sensor

It is suitable for measuring high-speed moving objects, such as measuring the runout of high-speed motors, dynamic measurement of camera module actuators such as smartphones, and evaluation of high-speed vibrating VCM for laser projectors.
The measurement data is output in analog (±5V), allowing sampling at 10 kHz.

AT-2060
Main specifications
Measuring range: φ2deg

Measurable distance: 150±10mm
Repeatability: 1.44sec
Dimensions: W100×D150×H56mm

KT-1530

Screen tilt sensor

It is a model that a screen with a scale is mounted on the front of the main body.
Reflection spots are projected directly onto the screen, so the measured values can be visually seen.
Since peripherals do not need to be connected in addition to the power adapter for LD, space-saving and low-cost deployment is possible.

Main specifications
Measuring range: ±30min
Measurable distance: 0 to 100 mm
Display scale: 2min

Dimensions: W50×D210×H54mm

KW -0001

Parallelism tilt sensor

It can be used to check the angle of facing surfaces.
Handlers devices such as chip mounters must be parallel to the reference plane (stage plane).
There are also methods of adjusting using dial gauges and pressure-sensitive paper, but our parallelism tilt sensors can significantly reduce work time.
It’s easy to use. Since the beam is emitted in two directions up and down, parallelism can be measured simply by inserting this sensor into the gap between the stage and the handler device.
You can easily manage the numerical value of parallelism.

Main specifications
Measuring range: ±30min
Measurable distance (top to bottom distance): within 50mm

Dimensions: W115×D50×H20mm
