Quality Management
To meet the demand for “high-mix, low-volume” products, we will outsource the manufacturing section based on cell production.
We will establish a comprehensive operation and management system, and conduct our own quality inspections in line with the application.
Various optical evaluation and testing equipment will be fully equipped to ensure higher quality control.

Shock resistance and vibration resistance test
The lens is tested for shock and vibration resistance by subjecting it to impact and vibration as shown in the image below.
Images are verified prior to and after the inspection to confirm that they meet our standards.
Shockproof
Vibration resistance
For problems with strong vibration/shock
Inspection is available for vibration and shock resistance in an environment that matches the customer’s usage conditions.
We can also perform inspections under conditions other than those specified in our standards, so please feel free to contact us.
Proposal of vibration and impact resistance
We understand that there are various concerns depending on the use conditions of our customers.
Based on our experience and expertise, we will make a proposal tailored to your needs to maximize the performance of our products under typically difficult operating conditions.
