7.3.3 Use anti-static containers for transport and storage.

7.3.4 Laser deterioration and damage can occur due to excessive current spikes when the power is

turned on or off. Design circuits to avoid the generation of excessive current spikes.

7.3.5 Inductive surges near equipment that emits high frequency EMI can damage or destroy lasers.

Avoid using lasers near fluorescent lamps or other sources of EMI emissions.

7.4 Soldering

Use a grounded soldering iron to solder laser leads. Solder at a temperature of no more than 250

℃

for a maximum of 3 seconds, at a point at least 2 mm from the base of the leads .

7.5 Handling laser diodes

Never touch the glass window of the laser. A damaged or dirtied window will impair the performance of

the laser.

7.6 Handling packages

Due to the glass window in each device, packages must not be dropped or subjected to excessive

pressure.

7.7 Safety

It is extremely dangerous to look, either directly or through a lens, at the laser beam emitted from a

laser diode. Use a TV camera or other similar device to adjust the optical axis.

8. Quality assurance

8.1

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. To ensure these

characteristics and product life, we manufacture our laser diodes based on comprehensive data

control using our own custom manufacturing, measuring, and inspection equipment.

8.2

Quality assurance system

8.2.1

After the wafers have been manufactured, electrical and optical characteristics are measured

to verify that characteristics can be achieved as the manufacturing process progresses.

8.2.2

In-process inspections are conducted at various manufacturing points to ensure the stability of

our assembly operations.

8.2.3

All products are burned-in to minimize initial and random failures.

8.2.4

Characteristics of all products are tested before shipping.

8.2.5

Products are managed by wafer lot.

8.2.6

Reliability tests are performed on randomly selected samples.

8.3

Quality assurance measures

8.3.1

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.

8.3.2

Measurement instruments used during the manufacturing process are regularly inspected and

calibrated based on company measurement control standards.

Security

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
