Quality assurance 
Laser diodes (semiconductor lasers) have a much longer life than other lasers such as gas or solid-state lasers. The 
components of our lasers have optimum characteristic ranges.  
1.Quality assurance system 
(1) After the wafers have been manufactured, electrical and optical characteristics are measured to verify that 
characteristics can be achieved as the manufacturing process progresses. 
(2) In-process inspections are conducted at various manufacturing points to ensure the stability of our assembly 
operations.
(3) All products are burned-in to minimize initial and random failures. 
(4) Characteristics of all products are tested before shipping. 
(5) Products are managed by wafer lot.  
(6) Reliability tests are performed on randomly selected samples.

Quality assurance measures
(1) Materials, manufacturing conditions, and inspection are controlled and maintained based on company set 
standards. Temperature, dust, humidity and other environmental conditions are also controlled based on company 
standards. 
(2) Measurement instruments used during the manufacturing process are regularly inspected and calibrated based on 
company measurement control standards. 
Safety 
The laser beam emitted from a laser diode is almost invisible to both the human eye and the animal eye, however, it 
will injure the eye and sufficient caution must be exercised to avoid direct exposure or exposure through a fiber to the 
beam when a laser diode is in operation. 
To adjust the optical axis or perform other similar work, we recommend using an infrared-sensitive ITV camera. 
We also recommend that protective glasses be worn.
