Development Background
Is it possible to measure the OIS lens actuator of a smartphone camera with a single unit? We developed this system based on such a customer’s request.
The conventional method was to measure X, Y, and Z with three laser displacement meters each and tilt with one autocollimator, but this method required space for four sensors, alignment between sensors, and management of the sensors. We have solved this problem by developing a product that combines the autocollimator method (tilt), the triangulation method (height), and a vision sensor (position).
Features
1. Combines triangulation, position measurement, and angle measurement in a single sensor
2. Excellent repeatability and highly accurate linearity
3. Wide working distance range for easy setup and operation

*1. Only reflected light from the target mirror is received by the sensor, so there must be no reflection from the φ7mm area aroundthe target mirror. FH-2304 (reflectance 80% or higher, size φ2.9 mm, thickness 0.3 mm ±0.05 mm, parallelism within 30 arcsec).
*2. Circular range.
